Plastic-on-plastic non-adhesion for pre-assembly - 14 years ago
Another line of thought that seems worth exploring is the idea of 3D creation of assembled plastic parts that are not bonded together. Since it is all made with hot-melt plastic, the question is how to separate layers so that they don't bond. Two options come to mind: - powdered graphite - powdered talc The process would be to apply a coating of powder between surfaces that should not bond.by Dale Mahalko - General
Dual-head, plastic/wax printer, for voids and support? - 14 years ago
Has anyone tried using wax as a temporary supporting material for complex 3D plastics printing? A forum search doesn't turn up any mention of wax. As far as I know, wax melts at a lower temperature than most plastics, so wax could be used for structural support when building complex 3D shapes with voids or overhangs. Once the part has been completed, it would be gently warmed until the wax runsby Dale Mahalko - General
