3D Printing Processes
By way of the developments of mannequin 3D printing formulation, there was additional analysis into manipulating the properties 3D printing supplies present. A brand new white paper by Dymax incorporates a research that targets superior impression and temperature resistance properties in photopolymer-based 3D printing resins. The aim is to create resins that meet or exceed the capabilities of thermoplastic supplies. Enhancements in impression energy whereas sustaining a excessive Warmth Deflection Temperature (HDT) can present perception about replicate thermoplastic properties in 3D-printed supplies. The information gathered on this white paper allowed for brand new developments in light-curing 3D printing processes. This info proves that it’s attainable to enhance each HDT and impression resistance concurrently, reasonably than sacrificing one for the opposite.
Printability was a big a part of this white paper research, as there are numerous limitations to the 3D printing course of. Limitations embody low formulation viscosities, restricted gentle supply intensities, and treatment dynamics of the 3D printing course of. To determine the most effective choices for 3D printing oligomer improvement, the research explored enhancing impression resistance by modifying arduous, extremely crosslinked networks with versatile impact-modifying resins. A number of experimental arduous resins had been examined each alone and along with a number of impression modifying supplies in a mannequin system. These supplies had been categorized by performance and molecular weight and included a variety of spine chemistries. The arduous resin and impression modifier formulations with the most effective stability of HDT and impression resistant properties had been subjected to further testing to determine potential relationships to tensile energy and elongation.
The outcomes have allowed Dymax to broaden their information of light-curing 3D printing processes and achieve highly effective perception into enhancing each HDT and impression resistance concurrently.
