The meaning is still the same. For me, I am saying I am going to revisit my attempts with Resin based high-definition 3D printing for making master models for casting metal jewelry items.
Using wax master models (in lost wax casting) remains the ultimate choice for me in high quality models and excellent burn-out in the casting process. The attraction of 3D prints is for making detailed models that cannot be hand carved or 3 and 4 axis machine-milled in wax.
The very best surface finish quality 3D prints are made using photosensitive resins and extremely small (0.035mm) layering. My previous attempts with 3D printed masters resulted in inconsistent burnout of the resins from the mold investment.
The solution is to use only the very best (and expensive) casting resins specifically designed for clean burn-out. Those resins required a printer of sufficient power to completely cure the resin on exposure.
My WanHao D7 shown elsewhere on this website is/was not quite up to the job on slow cure resins. The casting resins I could use with the D7 gave me inconsistent results as mentioned above. I abandoned my attempts, and much time passes.
My residence suffered a direct lighting strike last year. I just now discovered the Wanhao D7 must have suffered some damage from the EMP of the strike. The electromechanical parts, the cooling fans, start but the printer is unresponsive to computer inputs. I never thoroughly tested the printer after the strike as it wasn’t being used.
It’s a mixed blessing and curse. Total replacement of the electronics is about $200. But newer and far better 3D printers of this type now exist. The hardware is so improved, it is much better to upgrade than repair.
I have replaced the Wanhao D7 with the Anycubic Photon Mono SE.
The physical size/print capacity are nearly the same with both. The mechanical and hardware difference is a giant leap improvement in the Photon Mono SE. Prime improvements are dual Z axis linear bearings, anti-backlash z axis drive, huge UV exposure improvement in Light unit and 2K mono video screen.
Enough improvements in hardware that I am willing to re-visit 3D prints for use in metal casting masters.
I will cover the casting results in my KautzCraft Studio Blog. The new resin 3D printer shown here will from this point be the AnyCubic Photo Mono SE. The Wanhao D7 Rhino is now a goner. It was fun and useful while it lasted.
