FDM – Fused Deposition Modeling
When there are specific requirements in terms of materials FDM-technique can often be the best AM-method to choose. The wide range of thermoplastic materials enables applications like a single prototype, manufacturing of small series, fixtures and jiggs and more. Properties that stands out are V0-rated, antistatic, UV-stable and FDA-approved. Accuracy in shape and dimensions are good, strength in Z is reduced compared to X & Y. Compared to SLA the FDM-technology results in reduced part resolution, the surface finish has got a different appearance, it is a bit rougher. Build time for a single part can be fairly short, manufacturing a larger number of parts will however increase build time substantially. One single FDM-part can be fairly cheap, SLS-technology will however give better value-for-money if more parts are required. Build orientation severely impacts the end result of the parts, when specific reqirements aply a dialogue is always preferable before quoting.
