In Short: The 3D Printing Process

3D printing process is not a very complex process. In fact, all the different components and tools have already existed in the current manufacturing sector before.

3D printable models can be created using a CAD software bundle implementing a 3D scanner, or by a plain advanced camera and photogrammetry programming. 3D printed models made with CAD result in lessened mistakes and these can be corrected before printing and fine-tuned before it is ready for implementation.

Computer Aided Design for 3D Printing

The manual displaying procedure of get ready geometric information for 3D PC illustrations is like plastic expressions, for example, chiseling. 3D checking is a procedure of gathering computerized information on the shape and appearance of a genuine protest, making an advanced model in view of it.


Before printing a 3D show from a STL record, it should first be inspected for mistakes. Most CAD applications create mistakes in yield STL files gaps, confronts normal, self-convergences, clamor shells or complex errors. A stage in the STL era known as “repair” fixes such issues in the first model. Generally, STLs that have been delivered from a model acquired through 3D checking regularly have a greater amount of these errors. This is because of how 3D examining functions as it is frequently by indicate point obtaining, remaking will incorporate blunders in generally cases.

Once finished, the STL document should be prepared by a bit of programming called a “slicer,” which changes over the model into a progression of thin layers and creates a G-code record containing guidelines custom-made to a particular kind of 3D printer (FDM printers). This G-code document can then be printed with 3D printing customer programming (which stacks the G-code, and uses it to teach the 3D printer amid the 3D printing process).

Microelectronic gadget creation techniques can be utilized to play out the 3D printing of nano scale-size articles. Such printed items are regularly developed on a strong substrate, e.g. silicon wafer, to which they follow in the wake of printing as they are too little and delicate to be controlled post-development. In one procedure, 3D nanostructures can be printed by physically moving a dynamic stencil veil amid the material testimony prepare, fairly practically equivalent to the expulsion technique for conventional 3D printers. Programmable-tallness nanostructures with resolutions as little as 10 nm have been created in this mould, by metallic physical vapor affidavit mechanical piezo-actuator controlled stencil veil having a processed nano pore in a silicon nitride layer.

Just to Sum It Up

The whole technology and the concepts have given birth to different process in the world of 3D printing. The following are some of the processes to name a few.

  1. Stereo lithography(SLA)
  2. Digital Light Processing(DLP)
  3. Fused deposition modelling (FDM)
  4. Selective Laser Sintering (SLS)
  5. Selective laser melting (SLM)
  6. Electronic Beam Melting (EBM)

With the world-wide interest shown in the process and funds being poured in to research and development for the refinement of the whole technology, we are soon to witness new horizons being conquered in the very new future.

3D Printing Basics for Beginners

We all have been hearing about the amazing world of 3D printing and the storm in the form of revolutionizing the manufacturing sector. This very concept will turn the current manufacturing process of machining, fabrication, casting and stamping a thing of past. So, what is it? Broadly speaking a process to manufacture 3D objects of any geometrical dimension by using digital model data derived from a 3D model.

There are two aspects of 3D object printing. The first, all the data of the object to be printed in digital format and second, and a machine that reads the digital data and pours in layer after layer of the manufacturing materials to create the final product. Example: you have a tube of toothpaste and you start squeezing it while drawing different shapes. But in real life scenario the deposition of materials to form the final object is controlled by a computer’s 3D images and the digital dimensional data provided by it.

A New Approach

The current process of manufacturing is a subtracting one and the new technology of 3D printing is additive one. If we have to make a pulley, today we cast it first and then using machining process slice away parts until you have the final product of the right dimensions. Something likes stone sculpting. You chisel out unwanted stone to get the final carving. 3D printing on the other hand is the exact reverse. You keep adding material in the exact proportion until you get the final shape as guided by a digital data feed. So, there is no material waste. There are quite a lot of that go into making a 3D printer. The important being the computer system that controls the movements to the exact nano dimension, the modelling and finishing.

New avenues in development

The official term used by the United States of America and the ISO technical standards committee is Additive Manufacturing (AM) to broadly define the process. Today this technology can be applied to almost anything. It is used in the making of Pizza, chocolates and other food items. It has been so fascinating that NASA has their eyes set on using this technology to print food in space. This technology has found its way into 3D printing of dresses, automobiles, aerospace and medical science with joint replacement and craniomaxillofacial reconstructions. Soon you would probably have a 3D printer at home that would be good enough to prepare you breakfast, lunch and dinner. That makes you thing if one day you could have a printer that could make a gun or a customized mobile phone for you. Well, that is a possibility. All we can say right now is that the process, standards and the laws governing them are in its infancy. With clear thinking and refinement everything would be put into place and we would have the right system in place.

With worldwide interest generated in this new concept, funds are being poured into research and development to refine the process. Today we can have a 3D printer for around $1000 though a very basic printer device.

Development of 3D Printing Technology

When we think about the 3D printing technology, most of us think of it as a recent development. Not many are aware of the fact that seeds of the technology were sown way back in the 1980’s. Then known as Rapid Prototyping technologies it developed into the amazing world of 3D printing. Broadly speaking a process to manufacture 3D objects of any geometrical dimension by using digital model data derived from a 3D model. This process has the entire ingredient that triggered the industrial revolution. This is because the procedures were initially considered as a quick, cost effective and more practical technique for making models for developing product in industry. The fascinating side of the story is that the main patent application for RP innovation was recorded by a Dr. Kodama, in Japan, in May 1980. Dr. Kodama did not apply for the full patent specification before the one year due date after the application, which was disastrous as he himself was patent lawyer. It was in the year 1984 when Charles “Chuck” Hull came up with the process of stereo lithography and claimed the patent rights for it. One of the biggest corporations operational in the field of 3D printing was then co-founded by him – The 3D Systems Corporation.

Old vs. New technology

At a time when casting, stamping, machining and fabrication were the in thing in manufacturing process of 3D printing technology (also called AM – Additive Manufacturing) using successive layers of materials to synthesize a 3D object by computers digital model data revolutionized manufacturing. Late 1980’s say the first Rapid Prototyping commercial system. The SLA – 1 developed and sold by 3D Systems. Simultaneously in the year 1987, Carl Deckard form University of Texas developed a parallel RP technology called the SLS (Selective Laser Sintering). He filed for the patent and issued on in the year 1989. With the whole idea catching up, new technologies and research to refine the concept began to take roots. Another process implemented by basic 3D printing machines RepRap model based on Fused Deposition Modelling patented by Scott Crump in the year 1992.

Europe was not to be left behind. In 1989 the German company EOS GmbH put its money on Laser Sintering process to carve a name for them in the world of 3D printing. The refinement continued with 3DP by Emanuel Sachs, LOM (Laminated Object Manufacturing) by Michael Feygin, Itzchak Pomerantz patenting “Solid Ground Curing Technology,” and William Masters patenting “Ballistic Particle Manufacturing.”


The simple but ground breaking implementation of inkjet printer technology has grown tremendously in the 1990s and 2000s. Today, we find 3D printing technology implemented to various industries like medical, jewelry, aviation sector, manufacturing and automotive. The year 2002 saw a fully functional miniature kidney developed using this technology that was to filter blood in animals. The year 2008 saw the very first self-replicating printer capable of printing a major portion of its own parts and components. The same year produced the first 3D printed prosthetic leg.

The potential of 3D printing technology is enormous. The technology is set to revolutionize the industries with research and developments into the existing technology being funded on large scale.

The Variety of 3D Printing Materials

The 3D printing technology has grown a lot, thanks to the global awakening to this new technology. Today when we talk about the possible materials that can be used to manufacture objects using this technology, almost all materials known to humans seems to a prospective candidate. Polyamide, aluminum, cobalt derivatives, gold, silver, bronze, materials used in Ceramics, meat and sugar everything and more can used in 3D printing technology. Metal 3D printing permits you to make practical models and mechanical parts from different metals and combinations.

Mechanical metals are laser sintered from metal powder. Accessible materials incorporate aluminum, stainless steel, bronze and cobalt chromium.

Let us take Aluminum

Aluminum is the main metal we offer that is combined and liquefied utilizing a laser from a bed of metallic powder. The 3D printing procedure is called specific laser dissolving. Creation happens on an assemble stage with backings to grapple the part. A bed of aluminum powder sits over an assemble stage. One layer at any given moment, the powder is liquefied by a powerful laser. The softened powder is immediately cooled to harden the metal. To shape the following layer, the fabricate stage is brought down and another layer of powder is dispersed with a coater. This procedure is rehashed layer by layer until the part is finished. Level ranges and edges print with a naturally created bolster structure to keep the component from drooping into free powder. The support is then expelled and cleaned far from the part amid post-preparing.

Specific laser dissolving is exceptional in light of the fact that the powerful laser gives enough vitality to warm the aluminum powder over the liquefying point. This procedure completely liquefies the powder as opposed to simply sintering it, making strong, homogenous aluminum composite. Aluminum has a matte dim wrap up. There is an inconspicuous shimmer brought about by the silicon particles in this material. Since this material is printed with bolster structures that are expelled amid post preparing, certain surfaces (where the structures were) can be marginally rougher, while the others are smoother.

The backings are required keeping in mind the end goal to abstain from listing into the free powder underneath that can bring about distorting or defects in your model. At times, these backings are hard to expel and desert a defective surface. The generation organizers do their best to arrange your models ideally to limit the measure of bolster structures required.

Plastic and Rubber

With Rubber-Like Plastic (Tango), you can recreate elastic with different levels of elastomer attributes including Shore Scale A hardness, extension at break, tear resistance and rigidity.

This material empowers you to recreate a wide assortment of completed items, for example, non-slip or delicate surfaces on buyer gadgets, medicinal gadgets and car insides.

The above text just studies a partial list of materials that can be used in the 3D printing technology. The list is endless. With the ever-growing funding for research and development for the AM technology new materials are bound to be added to the list.

3D Scan and Printing for Recreation of Old Paintings

We are all familiar with a number of the more famous paintings. We hear their names and immediately are aware of the artist that created the magic. Many of us have had to sit back and admire these works from a distance as touching these works simply was out of the question. As with many other fields, the world of art is coming into the modern age and thanks to the world of 3D scanning. A new group of people is able to enjoy art like never. These people are able to take a hands-on approach to these works of art, something that in the past was just unheard of.

Reasons Why Art Can’t be Touched

There are several reasons why the public is not allowed to get up close to the works of art. The main reason is the risk of damage to the painting itself. If people are allowed to walk up and touch these works of art, then there is a damage that is done to the oils used to make the painting. This over time will break the oil down and as a result, a priceless piece of art will be destroyed.

Another reason for this is due to the fact that having access that close to the painting does in a lot of ways lead to a security risk. This makes theft of the artwork that much easier and therefore will lead to there being a higher risk that someone will try to run off with it. While these have been good reasons in the past to limit access to these paintings, the advancement of 3D scanning makes it now possible to touch and feel the paintings in a whole new way.

3D Scanning for New Art Lovers

There is a whole new generation of people that are falling love with art and thus, they are able to through the advances that have been made in technology are able to touch art that had never before been able to have hands placed on it. This allows these people to be able to get closer to the art than they ever had in the past.

Thanks to advances in 3D scanning, priceless art pieces can be scanned and a 3D version of the painting can be made since it is being printed with materials that can stand up to people touching them, there is little to no concern that this would lead to the art deteriorating over time. This advancement is giving a new generation the chance to experience art in a way that has never been possible.

As time continues to go by, there will be more and more advances that will allow people to experience art like they never had before and bring a new experience to the art lover. No matter the artist, these works of art will live on forever in our hearts and in our minds.

3D Scanning for Museums and Archaeology

There are a great number of museums that are beginning to use 3D scanning for their exhibits to help and give visitors to their museums a better glimpse into the past. This is a new tool that in the hands of archaeologists as well as museum curators allow them to see details and create images like they had never been able to in the past. There are a lot of advantages to being seen using this technology and why it will be leading the way for the future.

Advantages of 3D Scans

One of the biggest advantages to using this technology is the ability to capture more details than what the human eye is able to catch. This is a lot better in most ways than having to rely on a 2D model that will just not be able to give the level of detail that a 3D model will.

Using 3D scanning can actually help to preserve history. There are certain areas where parts of the area are being destroyed via several methods from cultural battles and other things like erosion. With 3D scanning, the area can be mapped out and preserved at least in a digital form.

3D scanning also allows a new generation of visitors to visit museums via a virtual method. With 3D scanning, virtual exhibits can be created and allow people the chance to go and visit all while never having to leave their own home.

The ability to scan and replicate artifacts from an era long gone. Thanks to the advancements made in 3D scanning, we are now able to scan and print out replicas of dinosaurs and other artifacts that have long since been lost to time and the elements. Once the scan is complete, the archaeologist can print out the replica piece using any type of material that is compatible.

Ways That 3D Scanning Can Be Useful to Archaeologist

There are many ways that this technology can be very useful for an archaeologist. Things from replicating a piece that was thought to be long gone to repairing a broken artifact. These ways will be very useful in helping an archaeologist to bring the past alive for a new generation of visitors.

Let’s take for example an ancient pot is discovered from the Ming Dynasty. There is a piece of it missing, with the use of 3D scanning, an archaeologist can scan and print out a piece that will fit perfectly to fix the broken piece.

Another example is this 11.000 year old ox skull. Thanks to 3d Scanning it can be used for educational and research purposes, without fear of damaging the artifact.

Not only that, but the ability to repair pieces that are damaged helps to reduce the number of exhibits that will have to be removed from display. This is a huge advancement from the days when an exhibit had to be closed due to a piece being damaged. As advancements are made on this front, there will be more and more uses for 3D scanning in museums as well as out in the field with archaeologists. This is one of the tools that will lead the next generation of archaeologist as well as bring history like never before to a new generation of visitors to museums.

3D Scan for Making Replicas of Sculptures

Scanning sculptures is something new that we are seeing over the last few years. It has caught on in popularity for the mere fact that is cannot only help to repair damaged pieces of art, but it can also be used to expose more people to these magnificent pieces of art that might not otherwise be seen by new people on a regular basis. This article will discuss the process of 3D scanning and create replicas of sculptures as well as other pieces of art.

3D Scanning to Repair Damaged Sculptures

Taking the time to repair some of the damage that is created by time on a sculpture can salvage the piece and allow it to remain on display. This is a far cry from the old days where people had to take a sculpture off display simply in order to preserve it for future generations. With the new advances, this leads to more and more people to be able to see these sculptures and enjoy them as they were meant to be. If a sculpture does become damaged, there can be a simple 3D scan done on it to map out the damaged area and then simply print out a piece that will fit perfectly.

One example of this could be the Liberty Bell, we are all used to the crack that is in the side of it. Technology has come far enough that this crack could be fixed and for the first time in years, the Liberty Bell could be whole again. This is just one of the many examples of how this technology is able to be used to take something that was originally damaged or has become damaged and help to restore it to its perfect state.

3D Scanning to Make Replicas

Pieces of art that are home to one museum may not be seen by anyone unless they come to the museum, even in a virtual tour, these pieces may not be included in order to entice you to come in and see it in person. With the advancements made in 3D scanning, you are now able to see these sculptures in person at your local museum. This is all in part to being able to scan the original and then creating a replica out of many different printable materials.

One such example is a piece that was part of the Metropolitan Museum of Art. It was recently scanned and a 3D model of it was made and put on tour going to several museums around the country. The replica was so close to the original, that curators at the museum had to be careful not to send the actual sculpture by accident.

This process will be getting more and more advanced as the years go by and eventually this will lead to a new chance for people to see these works of art that might not otherwise have ever been seen by anyone else. 3D scanning to make replicas is going to in the end lead to a new experience for those that love art and those whose job is to bring that art to the public.

Protected Against Destruction

Those that ignore the decaying historic places and cities are bound to wake up one day to them being gone. This is a harsh reality that many of us are having to face as war and time have destroyed and chipped away at the historic significance that these places have. This is not just a problem in war-torn areas or places that have been abandoned. Places like Mount Rushmore are suffering from erosion and without the use of 3D scanning, they may never be saved and we will lose all records of them even existing. Unlike with scanning to fix broken pieces or to imitate a work of art, this type of scanning is used to preserve a digital version of these places.

Efforts to Save War-Torn Areas

There is an immense amount of effort being made to help and save a lot of the areas that have been war torn over the last several years. Before certain parts of the Middle East were attacked by ISIS, researchers went in and took 3D scans of the area to have a digital record of these places in case they were destroyed. One of these areas hit was Aleppo.

Here there were photos taken as well as 3D scans to preserve every detail of the area. Looking at these today as compared to the images we see coming out of the city have proven that the area was hard hit and had those scans not been in place, we would have lost the glory that Aleppo once represented. This is just one example of how 3D scanning has made sure that generations that come after us, are not put into a situation that they forget the history that once stood in these war-torn areas.

Fighting the Effects of Erosion

There is a strong effort being made to help and fight back the damage that is being done by erosion. Natural monuments and landmarks are showing the scars that have been part of the erosion process. Mount Rushmore is one of these areas that after decades of being exposed to the elements, are not hold up well and beginning to show signs of wear and tear. Scanning has been used in an effort to help and save in a digital form this landmark seeing as though it is not possible to do anything major to help reverse the damage.

This is something that was never possible many years ago, and thus, places that could have been scanned, have to live solely in the form of pictures and some areas are just lost forever due to never being photographed. This history that has been lost will never be salvaged again.

Going out of the way to capture history is still a very vital tool that researchers have in helping to preserve history for those generations that come later down the road. One day kids will be able to study and learn Mount Rushmore even if it is not in the glory of days’ past.

3D Printing Applications in Health and Food Industry

This technology envelops almost all areas of industry. 3D printing finds its application in the field of medicine, aerospace, shipping, chemical and food industry. With the on-going refinement in the existing technology it is capable of finding its application in almost anything we can think of.

Food Industry

This industry is one of key elements of life which is at the base of the pyramid of human needs. Conveying the sustenance business to the advanced age is one of the fundamental and progressive utilizations of 3D printing. Applying this innovation empowers quick computerized and repeatable procedures, flexibility in configuration, and additionally permitting huge and simple fluctuation of the cooking procedure which can be tweaked for every area or person. Utilizing mechanical layer based sustenance printing frameworks permits the formula of the nourishment to be digitized and spared keeping in mind the end goal to get ready extremely repeatable and fantastic dishes with no edge for administrator blunder. Likewise, the shape and improvement of the nourishment can be individualized in light of the client or the event.


Medical and health care is another sector where we find this application will be of enormous benefit. Across the world there is a growing need for organ transplantation and organ donations needs. Organ transplants have been effectively led for as far back as century; in any case, there has dependably been a lack of contributors or a failure to discover a match between the benefactor and beneficiary in time. 3D printing is a propelled late innovation in this field which can be a progressive option with an assortment of uses in the transplant and medicinal services industry when all is said in done. 3D printing examination is explored in different fields inside the social insurance industry; some of which are talked about in this area.

Specialists have demonstrated that 3D printed parts can be utilized as bone swap for individuals whom lost some portion of their skull or jaw in a mishap.

Dental industry has been utilizing counterfeit material for dentures, orthodontics, embed, crown, and extensions for a long time. As these parts are uniquely designed for every individual, the procedure is both tedious and costly. Immediate and aberrant 3D printing, to be specific printing the real part or a form, has been appeared to be a less expensive and quicker other option to traditional systems. 3D printing of human tissue and organs can upset the social insurance industry by augmenting the normal future and incredibly enhancing the personal satisfaction for a huge number of individuals. Organ beneficiaries will no longer need to sit tight months or years for a contributor with the right blood classification, organ transplant dismissal will be canceled, unlawful human trafficking for organ gathering can be limited, and war and mishap amputees can by and by increase full versatility. 3D bio-printing may have phenomenal outcomes on regenerative prescription and personal satisfaction while limiting moral and religious issues which presently encompass human developing life procedures.

These are just a few examples of the immense potential this technology holds. The amount of funds put into research and fine tuning the technology will help in many more areas of human life finding its application.

Bird’s Eye View of Cities

This may sound like a concept from another time, but the truth of the matter is that 3D mapping of a city has a lot of real advantages that you might not normally think about. Things like trying to determine what a house will look like when it is built were things that once were just left to chance and you hoped the outcome was decent. As time has progressed, the advances have been fast and great in this area and have allowed experts to map out a city area and give potential home builders a perspective as to what the view will be for a home or even an office building that is being planned.

3D Scanning for Home Builders

There are a lot of people that are looking to build their dream home in a city. In the old days, this would have been difficult to accomplish as you would not really have a shot at knowing what the view from your home. Thanks to the advancements made in 3D scanning, this is more able to deliver a more comprehensive idea of what things will look like when you wake up in the morning to have your coffee, or in the evening after a long day of working.

Having this information will be helpful in determining if a certain area that you are planning on building in will be right for you or not. Taking a little time to look at this in depth will give you a much better perspective as opposed to the old days of having to take an educated guess. This will give perspective builders a chance to pick the right view for their home.

3D Scanning for Buildings

In regards to buildings, there are a lot of people that will see the many advantages that come from this technology. It is an old saying in real estate and that is location, location, location. This is true in the fact that when a building is constructed, if the view is not what it should be, you can’t just pick the building up and move it, you have to live with the decision that you have made. As the technology gets to be more advanced, there is an increased amount of precision that can come from picking the right location. This was something that was almost unheard back in the early days.

Today, you can know how well will the current be in and around your building or where the sun will hit at the right time in the right place. All of these facts can be crucial in the locating of a building to help and get the ideal location. Many of the bigger companies these days are using this technology to plan out where they are going to build their headquarters. If even one detail is off, the whole experience will not be as great as it had been hoped for. With a little planning and a little money, you can work with an expert that will scan the area and give you as close to a real estimate on things as possible.
