Drip Tray for 4-Serving GRP 1060 George Foreman Grill

thingiverse

Somehow lost the drip tray/catch pan for my 4-serving George Foreman Grill. Designed a replacement using Morphi. I printed a version in Monoprice PLA and in Proto Pasta HTPLA , and then annealled the part in an electric oven for 15 minutes. I wanted to be able to run this part through a dishwasher, and be able to collect hot grease without warping. Annealing PLA should allow this PLA part to hold up at temperatures in the 70C (158F) range (not many dishwashers go above this temp). The HTPLA should do a little better, from what I've read. I anneal the PLA at 90C (194F) and the HPLA at 107C (225F) in an electric oven for 15 minutes. I set the parts on a piece of parchment paper on flat pan in a preheated oven for ~ 15 minutes, then let the parts cool in place for more than an hour after turning off the heat. Slow cooling is reported to be better than fast cooling. During heat treating, the parts changed dimensions a little, the width dropped by about 6 mm (1/4") in my case, from 286 to 280 mm. If the pan you use is not perfectly flat, the part will deform slightly during annealing, approaching the shape of pan. I've not done much with annealing PLA, but based on reading I think it will help improve the mechanical strength and temperature resistance of the final part and be an acceptable material for this application. I printed on a Prusa I3 MK3S and used 100% infill to improve mechanical strength and temperature resistance. I used PLA, but PETG or ABS should be at least as good, with better temperature resistance. This part is 11.25" wide. You could probably get by with as low at 10.5" You'd need to more careful about the drip tray placement. This is nearly the maximum width part I could make on my Prusa I3 MK3S, if I oriented the part diagonally on the print bed. The cooking area on this grill is 9.5" wide, while the overall width of the grill is 10.5" According to PrusaSlicer, this part uses 67 gms filament (PLA), and takes 5 hours to print in 0.2mm quality mode. In 0.3mm draft mode, which I used, the print time is < 3 hours. This part doesn't cost much, but shows out of stock when I check the vendor's website.
