Recently, FDM desktop 3D printers have high safety factor and strong maneuverability due to their security, which can directly see the whole operation process.
This is the most common polishing method, and it is also the most commonly used 3D printing post polishing.It can be polished by hand or by professional equipment (abrasive belt polisher).It should be noted that because it relies on manual or mechanical back and forth friction movement, sandpaper may have some problems when polishing relatively small models, so when polishing, it should remember not to over-polish, calculate in advance how much material to polish, in order to avoid excessive polishing and resulting in model scrap.
Of course, there are various types of sandpaper, mainly to distinguish by the thickness of the surface particles, the lower the sandpaper particles, the more rough the surface.There are 400 eyes, 600 eyes, 800 eyes, 1000 eyes, 1200 eyes, 1500 eyes, 2000 eyes…
The sanding order starts from the low mark, starts with 400 mesh, passes through 600 mesh, 800 mesh, 1000 mesh, 1200 mesh, 1500 mesh, finally grinds to 2000 mesh above to spray paint.
However, the surface of the printed object varies in flatness, or it can be printed directly from 400 to 800 eyes without having to follow a fixed order.Also need not go up again after 2000 eye spray paint coloring, of course, to 2000 eye effect can be relatively better.It still depends on the actual situation at that time.
There are many kinds of file, no specific mark, small volume, semicircle, straight plate, shape, etc., generally used to file hard parts.
It is usually used when the foundation is polished. After polishing with a file, there will be file marks on the surface of the print. If it is painted at this time, the file marks will be more obvious.

Of course, when buying suits, the more kinds of polishing heads, the higher the price will be. Large area printers can be polished by this kind of machines, but the details still need manual sandpaper to be polished carefully.
