3D Printed Molds and Cores
3D printed sand molds and cores were once an idea for the future but are now available to the foundry industry. These molds and cores are made without the cost of an expensive pattern. They are especially beneficial for small-run jobs or prototypes. Both furan and phenolic binders are available. Phenolic, however, offers higher tensile strengths at lower binder levels and yields a finer surface finish. Once a 3D STP File has been generated, the molds or cores can be 3D printed from those files and shipped to customers.
For 3D printed investment casting patterns, a PMMA (polymethyl methacrylate) binder generates the mirror of the part to be cast. This PMMA pattern is then coated in a shell as the foundry’s typical wax pattern would be. However, instead of baking out the wax in an autoclave, the PMMA pattern is flashed out, leaving little or no ash residue. The shell is then poured as usual. Again, the foundry yields a pattern without tooling.
The printer machines are also available for purchase. Contact Carpenter Brothers to discuss your project.

About Us
Carpenter Brothers, Inc. is the leading supplier of equipment, consumables, and technical expertise for the metal casting industry. Founded in 1917, by Everett and Milton Carpenter, the brothers were able to use their unique foundry experiences to solve the problem of the day: a reliable sand source. They got their foot in the door by selling natural bonded molding sand, which was mined by hand, loaded into horse-drawn carts, and then delivered to customers. Not only did they sell the sand, but their technical expertise was readily available for all customers, big or small, to help manufacture the best castings. After surviving The Great Depression, Carpenter Brothers, Inc. slowly increased the number of products it distributed and expanded its sales territory into what it is today.
Carpenter Brothers, Inc. has committed itself to its customer's success by providing exceptional service to go along with the superior products and equipment they supply. With multiple warehouses around the United States we can get you the products you need when you need them. Our logistics team can handle getting your order to you by truck, plane, or train. Our technical sales and engineering staff all have experience in the industry, so when you buy from Carpenter Brothers you gain access to all of our knowledge.
