FFF / FDM Filament printing

Fused filament fabrication is the most prevalent type of consumer and prosumer 3D printing. Utilizing thermoplastic filament, the material is melted down at a small extrusion tip, and a laid down in a thin line. Building up the object line by line, and layer by layer until completed. One of the most versatile printing methods, FFF printing offers a massive library of materials to choose from at a very affordable cost. When you’re unsure of which process to go with, FFF printing is likely the way to go.

Usually the most cost effective way of printing, producing good results, and offering a large build volume.

Cons

• Visible lines in the surface finish

• Relatively slow process

• Non-isotropic parts (part strength not the same across all axis)

• Minimum size/detail = 0.4mm

Pros

• Large build volumes (up to 1’ x 1’ x 2’)

• Huge material selection

• Lowest cost

• Dual extrusion (soluble supports, two color, or soft/hard in a single print)

• Adaptive resolution, can optimize for print speed, or high quality

Common uses for this process:

• Engineering prototypes

• End use parts

• Props / Cosplay

• Fixtures / Jigs

• Prosthetics & Inserts

• Robotics

• Enclosures

• General parts / repair

Special properties only available on FFF printing

• Carbon fiber filled materials

• Stainless 316L steel

• Dual materials (hard soft, two color, soluble support)

• Largest build volume for single object
