  Many product designers, manufacturers, and engineers will want to cut costs when creating a prototype, but that can be challenging as there’s the risk of compromising the quality and performance.  Vacuum mold casting  can be an excellent option to avoid those issues as it produces quality parts without the lead time and costs required in production tooling. The process is similar to duplication with a silicone mold.   Vacuum casting works on products of any size, making it possible to build anything from car bumpers to headphones. Reputable manufacturers offer a range of materials to suit every requirement so that you can get the most from the service.   How does it work?   Vacuum casting or urethane casting involves three stages:   1. Master model creation – The master model is 3D printed using SLS (selective laser sintering), stereolithography (SLA), or CNC machined.   2. Crafting the silicone tool – When the master model is ready, liquid silicone is poured arou

Additive manufacturing  or  3D printing  is a growing and continuously thriving technology. Today, it is not merely used in research, development, and prototyping, as many industries and enterprises find it useful for their production lines. 3D printing makes it possible for them to create, develop, and introduce concepts that were previously impossible, challenging, or costly to attain.   Many OEMs and large, successful organizations embrace additive manufacturing to fulfill their strictest performance requirements and standards. New applications continue to enter the scene as more organizations use 3D printing in product design and to supplement conventional manufacturing practices.   Additive manufacturing  or  3D printing  is widely used to build robust end-use parts and rapid prototypes. Some technologies make it useful for crafting functional models, aesthetic prototypes, master patterns or models, and low-volume production parts with complex geometries. We can understand
