The Nanotool ceramic-like SL resin is extremely accurate and is the only SL resin capable of withstanding temperatures in excess of 250C.
Stereolithography (SL) and laser sintering (LS) technologies have not changed significantly since their inception some 20 years ago.
In the case of SL, it still boils down to a liquid photopolymer in a vat initiated layer by layer by a high-powered laser.
For LS, it's still the basic process of sweeping layers of powdered plastic across a build chamber and sintering it layer by layer, again with a high power laser.
Other, less costly, processes such as FDM (fused deposition modelling) or 3D printing offered by Z- Corporation, have been brought to market in recent years, but generally at the expense of either quality, tolerances, speed, or post process part properties.
Materials are now available which offer crystal clear clarity (WaterClear Ultra 10122), extreme impact strength (DMX-SLT 100), heat deflection temperatures of up to 250C (NanoTool) and silicone-like flexibility.
DSM Somos has developed the Nanotool ceramic-like SL resin.
This resin opens up new applications for the rapid prototyping community.
It is ceramic-like and its current applications include rapid tooling moulds, prototype moulds for vacuum forming and complex tooling inserts.
It is extremely accurate and is the only SL resin capable of withstanding temperatures in excess of 250C.
In addition, because of its stiffness, accuracy and low water absorption, it is an excellent choice for metal plating, taking SL into areas of metal prototyping.
