Support materials are as essential to the 3D printing process as the actual base materials. Without support during the build there would not be a successful outcome.

These materials offer a better solution than the old physical support structures of the past.

Once printing is complete, the user simply removes any support substance from the finished part. Some 3D technologies use support materials that dissolve when placed into a chemical bath.

Others will use the surrounding powder as a way to keep everything in place. And there are those which use a squidgy, gel-like substance.

You will read about which printing process uses what kind of support materials in this guide. Those who use this technology are serious about accuracy and precision.

It can produce objects from 3D CAD data computer-generated files in just a few hours. Machines that use this technology produce unique models, patterns, prototypes, and various production parts. They do this by converting liquid photopolymers a special type of plastic into solid 3D objects, one layer at a time. The plastic is first heated to turn it into a semi-liquid form, and then it hardens on contact. The printer constructs each of these layers using an ultra violet laser, directed by X and Y scanning mirrors.

Just before each print cycle, a recoater blade moves across the surface to ensure each thin layer of resin spreads evenly across the object.

The print cycle continues in this way, building 3D objects from the bottom up. Once completed, someone takes the 3D object from the printer and detaches it carefully from the platform. The 3D part will usually have a chemical bath to remove any excess resin. What this does is render the finished item stronger and more stable. Depending on the part, it may then go through a hand sanding process and have some professional painting done.

SLA printing has become a favored economical choice for a wide variety of industries. Some of these include automotive, medical, aerospace, entertainment, and also to create various consumer products. The liquid plastic resin used by the printer goes into a translucent resin container. There is, however, one major difference between the two, which is the source of light. This process results in pretty impressive printing speeds.

With SLA printing, a laser has to draw out each of these layers, and this takes time. Another plus point for DLP printing technology is that it is robust and produces high resolution models every time.

This is something that not only reduces waste, but also keeps printing costs low. It uses production grade thermal plastic materials to print its 3D objects.

The sliced CAD data goes to the printer which then builds the object layer at a time on the build platform. It does this simply by heating and then extruding the thermoplastic filament through the nozzle and onto the base. The printer can also extrude various support materials as well as the thermoplastic.

For example, as a way to support upper layers, the printer can add special support material underneath, which then dissolves after the printing process. As with all 3D printers, the time it takes to print all depends on the objects size and its complexity. Like many other 3D technologies, the finished object needs cleaning.

About this book

Raw FDM parts can show fairly visible layer-lines on some objects. These will obviously need hand sanding and finishing after printing. Results: Of the search results, 36 articles were identified and included in this review. The articles spanned the various subspecialties of the field including cerebrovascular, neuro-oncologic, spinal, functional, and endoscopic neurosurgery.

Conclusions: We conclude that 3D printing techniques are practical and anatomically accurate methods of producing patient-specific models for surgical planning, simulation and training, tissue-engineered implants, and secondary devices. Expansion of this technology may, therefore, contribute to advancing the neurosurgical field from several standpoints.

This technique has enabled the fabrication of physical, 3D models from computer-aided designs through additive manufacturing, in which successive layers of material are deposited onto underlying layers to construct 3D objects. Several methods of printing have been developed that leverage unique material properties to selectively cure or fix specific areas on an individual layer.

3D Printing

Most notably, fused deposition modeling utilizes a thermoplastic material that hardens after being heated during extrusion, whereas stereolithography SLA employs a low-power ultraviolet UV laser to solidify a liquid photosensitive polymer. Within the last decade, applications for 3D printing technology have expanded greatly in the manufacturing industry as a result of numerous innovations that have markedly reduced production and technology costs, improved the level of accuracy of printed objects, and increased the range of printable materials.

These improvements have provided the capabilities to create a variety of products and even make this technology available to consumers for in-home use. Applications within clinical medicine are also emerging due to 3D printing's ability to produce individualized models, devices, and implants that can potentially improve patient care.

The field of neurosurgery, in particular, has experienced substantial progress as a result of the usage of 3D printing. Because most of the surgical procedures and corresponding pathology that neurosurgeons encounter involve intricate, minute anatomical structures that cannot be outwardly observed, neuroimaging has become an integral component of clinical practice.

Some of these include automotive, medical, aerospace, entertainment, and also to create various consumer products. The SLM approach above uses high-powered laser in a chamber of noble, or inert gas.

Wax casting has been a traditional process where the user produces high-quality, customizable jewelry. Since then, the evolution of the 3D printing technology has seen developments such as printed blood vessels, development of Do-It-Yourself kits allowing users to build their own 3D printers, a printed robotic aircraft, a printed prototype car, silver and gold materials used in printing, and the implantation of a 3D-printed prosthetic jaw into a 83 year-old woman suffering from a chronic bone infection.

Platform with completed layer moves down out of the way. As in many modern societies since the Industrial Revolution, the relations between workers, the proletarians, and the employers, the bourgeois, are often fragile and potential sites of conflict. These are typically those which focus on precise, durable, lightweight parts. They speed products to market and reduce costly mistakes — all while keeping your intellectual property onsite.
