Multi Jet Fusion or MJF 3D printing and Selective Laser Sintering or SLS are rapid prototyping printing methods. Both have pros and cons and use thermoplastic polymers as a primary ingredient. But multi-jet 3D printing process involves heating the polymer, whereas SLS uses a laser. So, it is clear they both have differences in working methods and other aspects. Thus to know the differences, this article will assist you by offering all the principal variations between them.
Strength
MJF and SLS are both incomparable in the matter of strength, but MJF is slightly in a better position than SLS. The manufacturer rated multi-jet fusion 3D printing at 48Mpa on paper and, on the contrary, SLS at 42Mpa.
Accuracy
Both technologies offer high accuracy. But SLS is more accurate than MJF. According to some research, the accuracy figure of MJF is +-0.25/100mm and +-0.3/100mm for SLS printers.
Material Properties
There is a principal difference between them in the materials used, as MJF offers Nylon 12 for parts manufacturing. But a user can get several options like nylons and TPU for printing and prototyping in SLS.
Color Variation
SLS manufactured parts are mainly white-colored, but SLS can dye to whatever color you like. But you will not get this advantage in MJF, as it only uses grey and black for its manufacturing parts.
The Crispness And Tiny Features
MJF is crispier than SLS for tiny details. If you want to make a hole to any parts using a metal casting service, you can get small round holes in MJF with perfection, but in SLS, the shape will be slightly elliptical.
Cost
SLS uses a laser for manufacturing and has more waste. But MJF utilizes a fusing agent for making parts, and waste is also nominal, making it cost-effective.
Part Size And Quantities
MJF build parts are small, and their dimension is 14.9X14.9X11.1 inch. But SLS is different compared to MJF as it is dimensioned as 19X19X17 inch. Besides, MJF is a quick process and can make multiple parts shortly. But SLS rapid prototyping services are not as fast as the previous one.
Conclusion
Hence, both can produce complicated and tiny parts accurately and are budget-friendly. But MJF is slightly better than the other. Besides, SLS supports multiple materials, but MJF cannot provide this benefit. So, if you want to deal with them, select any process carefully.
