I have now printed several litres of the UHT (Ultra Hard and Tough) material. I am VERY impressed by that, even without the tank heater and wiper and having to use “open” mode its vastly superior to ANY of the Formlabs materials as a general engineering material. The surface finish and print ability is fantastic using “Clear Version 2” as the setting in Preform.
I bought a l litre of their ENG1 material two weeks ago, and I am even more impressed. I checked sample printed test bars and before any further post cure UV exposure have got results for the UTS of around 80mpa. I never thought that a non reinforced 3d printed material would achieve anything like that. Surface finish and printability is excellent (equal to UHT) - Its not quite as flexible but still has flex and shows very little brittleness
I intend to try it again today after post cure treatment. They (3Dresyns) have suggested 395nm at 20mw/cm2 at 40c for 1 hour)
Again, I AM VERY IMPRESSED the material properties are fantastic. Have Formlabs anything similar in the pipeline (a new resin from them?) which will allow me (the person who paid good money to own the printer) the same functionality during printing as one of their other resins (Cartridge, wiper, heater). It would be good to use all the features of MY printer.
Just wish that I did not have the limitations of “open” mode…
