Abstract

A refurbishment kit for a multi-material membrane for a three-dimensional printing system includes a supply of coating material and an applicator for applying the coating material to a layer of silicone rubber of the multi-material membrane. The coating material is configured to reduce the surface energy of the layer of silicone rubber.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A refurbishment kit for a multi-material membrane for a three-dimensional printing system, the refurbishment kit comprising a supply of coating material, the coating material configured to reduce surface energy of a layer of silicone rubber of the multi-material membrane, and an applicator for applying the coating material to the layer of silicone rubber. 
     
     
         2 . The refurbishment kit of  claim 1 , wherein the applicator comprises one of a spray bottle, brush, roller, or vat for dipping. 
     
     
         3 . The refurbishment kit of  claim 1 , wherein the refurbishment kit further comprises a drying rack for the multi-material membrane for use after the coating material is applied. 
     
     
         4 . The refurbishment kit of  claim 1 , wherein the refurbishment kit further comprises cleaning solvent for the membrane. 
     
     
         5 . The refurbishment kit of  claim 1 , wherein the supply of coating material comprises a silicone elastomer. 
     
     
         6 . The refurbishment kit of  claim 1 , wherein the supply of coating material comprises a polytetrafluoroethylene (PTFE)-based material. 
     
     
         7 . The refurbishment kit of  claim 1 , wherein the supply of coating material comprises a solvent. 
     
     
         8 . The refurbishment kit of  claim 1 , wherein the layer of silicone rubber has a thickness of 0.03-0.1 mm. 
     
     
         9 . The refurbishment kit of  claim 1 , wherein the multi-material membrane comprises a fluorinated ethylene propylene (FEP) or polyolefin polymer film bonded to the layer of silicone rubber. 
     
     
         10 . The refurbishment kit of  claim 9 , wherein the FEP or polyolefin polymer film has a thickness of 0.03-0.1 mm.
