3D-Print Powder of Used-Coffee Ground

Material category:

Plant / Plant based

Identification number:

22-7359-323-a

Sample produced by:

WEI Gongqi William

Sample date:

29 Nov 2022 (Produced)

Sample condition:

Damaged

Process-driven material

This sample is composed of a 1:1 ratio of used coffee grounds and plaster. This mixture was 3D printed into a form through the method of non-supported cantilever that was achieved by traditional Selective Laser Sintering processes. The powder is agglomerated by rubber emulsion as the major bonding actant that was injected into each layer of the powder manually as an experimental trial.
