Application and audience
For slab-building potters making cups with a body wider than the rim opening.
Espresso 80 is a reusable tool for slab-built pottery. The digital file produces the forming mold; clay is worked around it to create a ceramic piece. Its target fired internal geometry was developed around a nominal 80 mL capacity.
Operation and assembly
- Insert the segments into the removable central pull-lock, alternating the four wide and four narrow segments. With the core installed, the assembly forms the working surface.
- Prepare and form the clay slab following the user manual.
- Once the clay has firmed, remove the central pull-lock. Move the narrow key segments inward to create clearance, then remove the remaining sections.
Dimensions and variants
- System
- 4 wide segments + 4 narrow segments + 1 removable central pull-lock
- Nominal fired capacity
- 80 mL
- Target fired inner rim
- Ø48 mm
- Target fired maximum inner diameter
- Ø54 mm
- Target fired inner height
- 41 mm
- Target fired flat inner floor
- Ø24 mm
- Reference compensation
- 12% linear shrinkage
Printing information
- Start with the print profile and consult the manual for clearances and tolerances.
- Do not scale the STL manually: scaling also changes interfaces, clearances and pull-lock operation.
Care and use
Clay shrinkage and the firing schedule affect final capacity and dimensions. Use the 12% reference as a starting point for your process.

Project questions
Does the file print the ceramic cup?
No. It prints the tool used to form clay. Drying and firing are part of the pottery process.
Can I change capacity by scaling the file?
Manual scaling is discouraged because it also changes the segmented system interfaces.
