[3D Printing Applications] The Secrets of 3D Printing to Casting: PolyCast

SanDima has shared many success stories about metal casting . Besides the finished products, are you curious about the production process? The following video goes straight to the factory to show you how lost-wax casting produces perfect metal parts!



Novel form of lost-wax casting

Traditional lost-wax casting requires a two-dimensional schematic diagram, with a craftsman manually sculpting a wax model, repeatedly communicating and refining it before proceeding to the casting process. If structural replacements are needed, even more time and steps are required. Nowadays, more and more people are using 3D printing for prototyping, which can be completed in a day or even a few hours within the company. The 3D-printed prototype can even be compared and tested with other assembly parts beforehand. If modifications are needed, only adjustments to the 3D file are required for reprinting, allowing direct entry into the metal casting process.



3D printing filaments designed specifically for casting.

This special filament, PolyCast, is categorized under Polymaker 's Specialty series and is designed specifically for lost-wax casting , offering a more economical and faster application mode. Using PolyCast filament with a 3D printer can significantly reduce complex processing steps and costs, and greatly accelerate product delivery cycles.



Two technologies, like adding wings to a tiger: Layer-Free and Ash-Free.

Layer-Free technology:
PolyCast 's 3D printed products are placed in an environment of atomized alcohol vapor, and the entire process is completed automatically within the Polysher alcohol polisher . The principle behind this is that the rapidly vibrating " atomizer " inside the polisher generates alcohol vapor. When the surface texture of the 3D printed product absorbs alcohol particles, a chemical change occurs, resulting in a smooth, glossy appearance with a polished effect (further reading: 3D printing polishing time-lapse video ).



Ash-Free technology:
PolyCast 's filaments, when used in lost-wax casting, can melt cleanly without leaving any residue. These clean cavities allow for the creation of complete, unbroken metal parts. This technology is leading to the increasing application of 3D printing in lost-wax casting and significantly reducing the high costs and production time previously required for producing small quantities of metal parts using CNC machining or mold making.



Use PolyCast to create your 3D printed parts

The good news is that while Sandima previously only offered casting services through partnerships, it is now available for online purchase! In addition to commissioning us for casting services , those with 3D printers can also purchase PolyCast filaments from the online store to create anything they want.
Using PolyCast's special filaments with the Ultimaker 3D printer to create cast parts yields cost-effective, high-quality industrial-grade results. Best of all, this allows for rapid adjustments and prototype replacements within the office. We appreciate the contributions of 3D printing technology to industrial processes.
