Multi Jet Fusion

MJF works by rolling a thin layer of nylon beads across the build surface. Next a printhead releases agents over the nylon surface defining geometry to be fused by the fusing lamp.

Advantages / Applications:

  • Best overall form of 3D printing mixing very high quality resolution with incredible durability and overall strength

  • Often used for final production runs

  • Great heat resistance

  • Accepts paints and dyes very well

  • 12 times faster than SLS 

Conclusion:

MJF is the most advanced form of polymer 3D printing comercially avaiable to date. Layer resolution combined with nylon's durability creates the perfect mix for final product prints. MJF has officially brought 3D printing to the level of final production.

Stereolithography

A Stereolithography apparatus works by curing a photopolymer resin with a laser building the part upside down layer by layer.

Advantages / Applications:

  • Highest Resolution form of 3D printing available on the market today (Up to 25 Microns)

  • Clear resin can be made optically clear

  • Most versatile material selection with over 20 different resins to choose from

Conclusion:

SLA is best suitable for individuals / companies looking to make very high quality prototypes with a glass like finish and no visable layer lines.

Fused Deposition Modeling

Fused Deposition Modeling works by melting and extruding thermoplastic filament to build a part up a layer at a time.

Advantages / Applications:

  • Low cost per part

  • Excellent for basic proof of concept and prototypes

  • Long list of potential materials for certain applications (PLA, ABS, TPU, PETG, Carbon Fiber, etc.)

  • Large build volume (12x12x15 inches)

Conclusion:

FDM is best suitable for those looking to make very low cost prototypes / models, where visible layer lines will not have an effect.
