Nylon with SLS print

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 start themselves. DIY
