      has anyone contacted buck town, i call the number on the website and it just asks for an extension. i am very interested in high speed fast cure strong resins and can deal with 'smell'.  i wanted to contact some there to get some resin fro them so if anyone has a better number or name let me know.

      If you work in a Chem lab you should have no problem working with the resins they used to offer the DIY crowd that are tougher than ABS. You have to be careful using the -V420 resins in printers like the B9 or Form1 since they cure so fast they can easily melt their vat materials. DIYers would complain about the odor and weren't interested in chemical resistance, tensile strength (>60MPa) or the flexural modulus (>9GPa)of some cured resins, only cost and odor. They have hundreds of formulas that target manufacturing vs hobby applications.
