Produce sand-casting tools and moulds for low-run part production, saving time and costs.
The mould is 3D printed using SL technology and then mounted into a box or board. Sand, the moulding medium, is mixed with a binder then packed around the mould which is filled up and packed tightly.
When the mould is removed from the board it is left with a negative. Molten metal is then poured into the negative and then once set, metal parts are produced.
3D printing patterns compared to traditional CNC machining allows manufacturers to design intricate and detailed parts due to SL technology printing patterns with greater accuracy and detail. Designs can be quickly iterated and reprinted in hours or overnight offering manufacturers greater flexibility.
Lead time is significantly reduced, waiting days rather than weeks to produce the final part. There is also an estimated average 70% cost savings with 3D printing patterns compared to traditional methods of CNC machining to create functional moulds.
