Fused Deposition Modeling (FDM) is changing the rules of design by offering a cost-effective production-grade method for complex builds. By building prototypes one layer at a time, you can do short run iterative testing and maintain design complexity to achieve functionality. Before FDM, engineers worried about design structures that were difficult to replicate. Now you can create functional prototypes, concept models, or production parts that - depending on part geometry - can withstand exposure to heat, chemicals, and mechanical stress for a fraction of previous cost.
All support material is removed before shipping. ABS and PC-ABS have a dissolvable support structure. Ultem supports are manually removed.
Fused Deposition Modeling (FDM) builds parts by heating material that gets fed through a print head after reaching a semi liquid state. It builds each part layer by layer adding support material where needed. Each layer is determined during setup where a program creates a path to build the part. Once a layer is complete the base moves down so the next layer can be added. Each layer is added until the program is complete and parts are ready to be removed from the machine. Support material is removed by breaking away the tiny pieces or placing the part in a water/detergent mix that dissolves the support material.
