Stratasys, a company from Minneapolis, Minnesota, has recently developed a thermoplastic that can replace handmade metal parts used in production and manufacturing.
3D printed molds using thermoplastics can replace hand crafted metal molds previously used in the production process. But replacing these parts are not the only type of metal parts that are being replaced in production by 3d printed thermoplastics.

A solution from Stratasys, Minneapolis, Minn. was recently unveiled when the company announced that Dutch 3D service bureau Visual First is using the company’s FDM Nylon 12 CF carbon-filled thermoplastic—containing 35% chopped carbon fiber—to replace those hook-shaped metal parts. The ability to 3D print machinery replacement parts on-demand, in this case using the Stratasys Fortus 450mc Production 3D Printer, has significantly reduced machine downtime, ensuring production line continuity for the company.
According to Visual First’s business owner Carl van de Rijzen, the company can 3D print and deliver production parts to The Chocolate Factory in under a week and its client is impressed with the high stiffness-to-weight ratio of the FDM Nylon 12CF, that result in parts of extreme rigidity. “The material is impossible to bend…the part withstood all tests on the machine and multiple runs were completed without incident. The factory is now enjoying increased production throughput by replacing the metal machine part with our 3D printed version.”
In follow-up to this success, The Chocolate Factory has now turned to Visual First to solve other design challenges; most notably, to develop a prototype casting mold to test acceptance of its products. Traditionally, this is made from plastic, which is both time consuming and expensive. “With 3D printed molds created in the Fortus 450mc, the company will be able to further accelerate its production processes,” said van de Rijzen.
Added Nadav Sella, head of Stratasys’ Emerging Solutions Business Unit, “We’re witnessing a growing demand for 3D printed production parts and replacement parts for industrial machinery, especially for packaging machines….These machines require high-level customization due to a large variety of products that are packaged. In many cases, the use of additive manufacturing can not only save time and cost during the manufacture of such machinery, it can also make them more efficient by reducing weight, simplifying the design and increasing functionality.”
