Manufacturing Process

The Fused Deposition Modeling (FDM) manufacturing process

Fused Deposition Modeling uses industrial Stratasys and Bambu Lab 3D printers with heated extruders and enclosed build chambers to melt and deposit thermoplastic filament layer by layer, creating strong, durable parts with excellent material properties. Controlled chamber heat minimizes warping on large parts and improves layer adhesion in engineering thermoplastics. Support material is removed after printing, leaving parts ready for post-processing.

Post-Processing

Material Surface Finishes

FDM parts have a distinct layer-by-layer texture with visible striations, resulting in a slightly rough, ribbed surface finish. While the natural finish is durable and functional for most applications, post-processing techniques can significantly enhance appearance and performance. Vapor smoothing chemically melts the outer surface, creating a glossy, sealed finish with improved strength. Performance painting provides a professional, polished look with custom color matching capabilities.

Standard Finish FDM Finish
Natural Finish

Standard Finish

FDM 3D printed parts have a visible layer-by-layer texture with slight ridges and striations, resulting in a rougher surface finish compared to other 3D printing technologies like SLS or SLA. Soluble supports are dissolved in an ultrasonic cleaning tank, while physical supports on high-temperature materials are removed by hand if required.
