HOW MSLA RESIN 3D PRINTING SERVICE WORKS?

 MSLA resin 3D printing service offers the cleanest possible surface finish out of all the 3D printing services we offer.

In order to understand how MSLA 3D printing works in detail, let us 3D print a model kit together.

First, a 3D model from Thingiverse was downloaded & then hollowed out to 2mm thickness with drainage holes. This was necessary in order to make the model printable and also cost-effective (save materials).

Then supports were auto-generated at a 50% density for all overhangs steeper than 55 degrees.

Since auto-generated supports are never quite perfect, manual supports were added layer by layer. This is a painstaking process that can take tens of minutes to maybe even an hour long.

After that, the model could be 3D printed by cross-linking a tub of photosensitive monomers layer by layer hundreds or even thousands of times using the 405th nanometer light.

This was best done outdoor in a workshed with carbon filter, respirator, and nitrile gloves.

Often times, the model doesn't come out perfectly the first time. Each time there was a failed print, the model needs to be re-supported and reprinted (in addition to all the cleanup necessary to remove the failed print).

If the print was successful, the object needs to be cleaned in ultrapure lab grade IPA to remove all the resin sludges.

Then, the print was UV-cured underwater for a whole day to make sure all the corners and crevices were fully cross-linked.

Here was the model all finished!

All resin 3D prints could be painted & finished just like any other plastic model kit! Here was one of our favorite models that we painted using miniature paint.
