New! 3-D printed molds
Make a small part mold for
less than $800.
This part is a star that fits onto Christmas tree
lights. Two identical pieces snap onto each other to form the star. The snaps
are too fragile to be made with 3-D printing, but the molded parts work
perfectly. We have made over 1000 parts with this mold in polyethelyne without
any noticable degradation of the mold.
Because of the low thermal
conductivity of the SLA material it takes a minute cool-down between shots, so
it isn't suitable for low-cost production.
The parts show the stepped digitization of the SLA
printing process, but adequately show that the parts work as designed, and has
produced a fully functional part using injection molded polymer that cannot be
