Fused Deposition Modelling

• Pre-processing: Build-preparation software slices and positions a 3D CAD file and calculates a path to extrude thermoplastic and any necessary support material.
• Production: The 3D printer heats the thermoplastic to a semi-liquid state and deposits it in ultra-fine beads along the extrusion path. Where support or buffering is needed, the 3D printer deposits a removable material that acts as scaffolding.
• Post-processing: The user breaks away support material or dissolves it in detergent and water, and the part is ready to use

Advantages: Fast, Low (Tooling) Costs, lots of different materials to be used.

Cons: Low-Mid accuracy, postprocessing.

Acylonitrile Butadiene Styrene

ABS offers a wide range of colors including ivory, white, black, dark gray, red, blue, olive green, nectarine and fluorescent yellow – plus the option for custom colors. Parts 3D printed in this material are mechanically strong and stable over time. Because ABSplus works with soluble support materials, support removal is hands-free, and complex shapes and deep cavities require no extra effort.
