There are multiple metal materials available for DMLS, including aluminum, cobalt chrome, maraging steel, nickel alloy 625, nickel alloy 718, stainless steel, and titanium. Similar to Selective Laser Sintering (SLS), metal layers are repeatedly laser sintered, creating the desired three-dimensional piece based on a 3D CAD model or STL file. In DMLS, 3D metal parts are created by fusing, or sintering, powdered metals with the heat from an infrared laser beam. This process is typically used for highly complex, intricate parts that would be difficult or impossible to produce with traditional methods. Although DMLS typically costs more than other rapid prototyping techniques, no special tooling is required, allowing for turnaround times of 2-4 weeks. Projects that require a higher level of surface finish and accuracy than sand casting can achieve.ĭirect metal laser sintering (DMLS) is an ideal rapid prototyping solution for customers that need high-quality 3D metal parts or metal prototypes quickly.The key difference is that the molding material is plaster of paris, rather than sand. Plaster mold casting is extremely similar to sand casting. Rapid prototype turnaround, with metal parts being created in 2-4 weeks or less, depending on foundry capacity.Smaller-budget projects sand casting is the least expensive way to create short-run metal-cast prototypes and products.Mold sands that are used in sand casting include silica sand, olivine sand, chromite sand, zircon sand, and chamotte sand. Sand casting, also called sand-molded casting, is a metal casting process that uses sand as the tooling material. Highly accurate, high-quality projects parts require little post-casting machining and processing to remove flashing and surface preparation, and ProtoCAM’s proprietary investment casting methods allow for walls as thin as.Rapid prototype turnaround, with metal parts being created in 2-4 weeks or less, depending on method and foundry capacity.Fast creation of multiple metal parts without the expense of conventional tooling.Parts can be created from steel, Everdur (bronze mix), aluminum, and ferrous and non-ferrous metals. Investment casting, also called lost wax casting, uses a 3D-printed wax pattern, a cast wax pattern, or an SLA QuickCast pattern. This process is ideal for the rapid creation of short-run metal parts with a high degree of accuracy, durability, and quality. These methods are far faster than conventional tooling and machining methods. Metal casting techniques at ProtoCAM include investment casting, sand casting, and plaster mold casting. accelerated business development and helped reduce risk as we approached tooling." - Michael DiCanzio, independent Aesthetics were crucial, and unless told otherwise, no one was able to identify the product was 3D-printed. "The Carbon 3D printing process was the perfect half step between late-stage functional prototyping and production. Their knowledge of stereolithography and CAD, and their application of these technologies has helped us reshape our ideas to reality in the shortest possible time frame." - Kenneth Raines, B. "ProtoCAM has been most helpful in responding to our needs. "As an emerging 3D modeling student at DeSales University, it was an incredibly valuable opportunity to learn more about the new innovations in 3D printing technology and how ProtoCAM couples its technical expertise with artistic value such as custom finishing to deliver a final product that exceeds the client's expectations." - Austin Kaplan, Desales University ![]() There's a lot more value added in working with ProtoCAM.” - Matthew Bellenoit, B. “ProtoCAM's turnaround times are exceptional, and their prices compared to others are always better. ![]() ![]() ![]() Their willingness and desire to keep in touch with me is impressive, and physical walkthroughs ensure quality standards are being met.” - Todd Frick, Versatek “ProtoCAM's best attribute is their attention to detail and customer service. You guys knocked it out of the park!" - Chris Davenport, RPC Quoting was prompt, engineering emailed and we spoke on the phone about a potential issue with the geometry of the parts so there were no surprises, the service was fast and delivery quick, the printed parts were of excellent quality, and all of the staff I dealt with were courteous and professional. "Our first experience with ProtoCAM last month was excellent.
