3D Printing News Unpeeled: Multimaterial DLP Through Centrifugal Force

Jianxiang Cheng at the Shenzhen Key Laboratory of Soft Mechanics & Smart Manufacturing of the Southern University of Science and Technology in Shenzhen has shown a process of using centrifugal force to rid a model of excess uncured resin. This enables multimaterial 3D printing using several different resins in one model. The idea was inspired by dogs shaking water off their fur. This lead to the the team to spin the build platform in between material switching to reduce contamination. True multimaterial DLP is a significant step forward towards making complex integrated devices in one print job. Sidne Fanucci and Earl Prinsloo have managed to make a $1008 bioprinter. Using an Anycubic Kossel with an Adrian Bowyer designed paste extruder they've made an enclosed hydrogel micro extrusion system called the SidneV1.
