Current practice-oriented understanding of how a material destined for 3D printing processing interacts with printers is inadequate. The thermo-mechanical processes which materials must endure during 3D printing processing are very influential. For high temperature thermoplastics and reinforced polymer matrix materials it can be a technical challenge to bring printed parts to fully conform to design tolerances. This presentation will focus on the development of a printing process control tool for high temperature polymers. The role of temperature, printing speed and fundamental material properties will be highlighted.

Supramolecular polymers, based on hydrogen bonding are eminently suitable for FDM 3D-printing. The thermo-reversible nature of hydrogen bonding favors the interplay between the intrinsic processability and the mechanical properties of the polymer and is therefore lowering its printing-temperature while retaining its mechanical performance. Furthermore, the specific rheological profiles of supramolecular polymers may lead to unique dynamical properties like self-healing behavior.
By using our SupraB™ hydrogen bonding technology, we have developed various polymers for 3D-printing ranging from strong biocompatible elastomers, to elastomers with self-healing behavior, to soft hydrogel materials with shape-memory properties.

Colored 3D prints are the coolest, but they’re often not the most resistant over time. We’re launching a new grey plastic to take care of that. Thanks to some science and a lot of tests, we’re now able to offer you a 3D printed plastic that is grey throughout the material. Continue reading “Sculpteo Introduces New Grey Plastic Material”
Cornell researchers have developed a new lightweight and stretchable material with the consistency of memory foam that has potential for use in prosthetic body parts, artificial organs and soft robotics. The foam is unique because it can be formed and has connected pores that allow fluids to be pumped through it.

Researchers at the University of Groningen in the Netherlands have created a process that can manufacture 3D-printed teeth and braces which are actually good for your other teeth, and dental health in general.
3D-Printable Antimicrobial Composite Resins [paid PDF access] outlines the development of the new plastic resin used in the process, which involves embedding antimicrobial quaternary ammonium salts inside extant dental resin polymers. Because the salts are positively charged, these disrupt negatively charged bacterial membranes, resulting in them bursting and dying. The mixture was then hardened with ultraviolet light. Continue reading “New Antimicrobial Composite Resins Make Possible 3D-Printed Teeth that Kill 99% of Bacteria”
Gone are the days of 3D Printing being synonymous with Rapid Prototyping; the days of Additive Manufacturing are here.
Since the 1980s, when 3D Printing was first commercialised, it has grown reasonably slowly, being adopted mostly for small scale prototyping. Continue reading “3D Printing Materials Market to Overtake 3D Printer Market in 2023, Projected to Reach $8.3bn by 2025”
While several companies have developed 3D printing materials and processes with similar properties capable of simulating silicone, so far 3D printing with actual silicone materials hasn’t been possible. However, 100 year old chemical manufacturing giant WACKER CHEMIE revealed in their recently released Q2 Report that their WACKER SILICONES division has developed new technology making it possible to use silicone 3D printing materials with additive manufacturing technology. Continue reading “Chemical Manufacturer Wacker Reveals New Silicone 3D Printing Technology”
Macadamia shells are already used as a biofuel. Australian researchers are now proposing to use the nut’s extraordinary properties as a basic element in a new Microtimber, made using pioneering 3D-printing technology. Until now, this technology has been primarily used for small-scale, industrial design products. Continue reading “Development of new microtimber using 3D printing”
Of all of the things in the natural world, spider webs have consistently been one of the more fascinating biological structures known to man. Between its high-strength properties (ounce for ounce it’s stronger than steel) to its complex mathematical patterns, the spider’s web is nothing short of one of nature’s most impressive structures. Continue reading “MIT Researchers 3D print synthetic spider webs to help design materials with high strength & low density”
Aerospace engineers at the Technicon-Israel Institute of Technology have used 3D-printing to experiment with the design of new materials inspired by fish scales. Assistant professor Stephan Rudykh, head of mechanics at the soft materials lab, set out to design a new material that mimicking fish scales … Continue reading “3D Printing And Biomimicry Combined In New Material Design”
