VisiJet® (MJP)
Very finely detailed, smooth plastic parts printed with melt-away wax support.
What is VisiJet® (MJP)?
MultiJet Printing (MJP) jets photopolymer as droplets and cures it with UV, while supports are printed in wax that is melted away with heat. Since no support marks remain, very fine details, smooth surfaces and internal channels are achieved. Some grades (e.g. VisiJet M3 Crystal) are USP Class VI biocompatible.
- Fine detail
- Transparent
