Typically, this is part of our normal review during our quoting process. Injection molding with 3D printed molds may be a good option for businesses with access to an SLA or material jetting 3D printer. You may also post-cure this resin and make it harder in order to polish it before taking RTV liquid mold… Resins typically have a shorter “pot-life” than silicone meaning they will cure faster. To ensure the best results the designer smoothens the printed mold boxes internal surface. Ink doesn't transfer well to printed parts when the layer lines are vertical, so we'll need to use casting putty to create our stamp molds. 32 vendus. I already tested and got a nice result. The solution: use 3D printing to make a mold. Much like Sylatech, Siemens uses 3D printers to print prototypes, which are eventually used to create molds for casting steel. The quality of the silicone mold negatives affects directly casted objects. Nowadays, technology developments in printer accuracy, surface finish and materials allow 3D printers to also directly manufacture the molds. In many parts, a support material can be printed into the open space and can allow for significant undercuts, as shown with the part below. Once both halves of your mold have cured you are ready to remove them from the mold box and begin using them to recreate parts.
