Printing the mug model and casting it in plaster
This picture has its own page with more detail, click here to see it.
I 3D printed it using PLA and poured it full of plaster. When the plaster set I peeled the printed shell off. The plaster part is the drape-mold around which the mugs can be formed (according to how the cookie cutter works I will change the size or either this to that). The surface roughness on the plaster was easy to remove using a metal scraper, then sand paper. I normally name 3D prints of this like this: TopDia-BottomDia-Height (making this one 94-66-110). But in this case, I want to maintain the same draft angle (8 degrees), so this is named 66-8-110 (BottomDia-Angle-Height). On first use with my 45-25-108 cutter it was evident that this form is too small. It needs 10mm more of height and 4mm more diameter (so I adjusted it to 70-8-120).
