Nylon with SLS print

Metal 3D printing allows unparallel opportunities in all manner of industries including automotive, aerospace and medical.

In all 3D printing technologies, SLA can be considered the gold standard:

1) It is the earliest 3D printing technology with high maturity;

2) Good surface quality and high precision (around 0.1mm);

3) The diversity of printed materials, with a wide range of functional materials, can be selected according to their needs;

4) Prototype generated directly from CAD data, fast processing speed, short production cycle, and no secondary processing of cutting tools.

But the shortcomings of the same SLA technology are also obvious:

1) The system is expensive and the maintenance cost is high;

2) High environmental requirements, toxicity, and odor, and need to be enclosed;

3) The operation of the software is complicated and requires a certain degree of professionalism.

Of course, the above are all for professional 3D printers. With more and more people knowing and using 3D printing, more desktop-level printers are beginning to appear in the hands of makers, and even more people are starting themselves.
