RepRapMicron Makes use of Fibre Optics To Print Tiny Benchy In Resin

The RepRapMicron (additionally µRepRap) is just about the microscopic tackle what RepRap did for extra macroscale manufacturing, with the newest innovation being a UV print head, known as the PIKA UV Head. What this does is use off-the-shelf optical fiber and UV LED modules to create 3D buildings in-situ in a UV resin, permitting for fairly small buildings to be printed, all the way down to a decision of about 9 µm.

More photographs of prints might be discovered on the blog page with hyperlinks to YouTube movies. It’s naturally considerably difficult to get clear images of a 3D print that’s sufficiently small to lose perpetually for those who a lot as sneeze or breathe too loudly.

For the UV head meeting a single mode fiber optical cable was used within the type of a daily patch wire that acquired trimmed a bit with a hacksaw. This was utilized in mixture with a “3W” UV LED module, which can or is probably not its true score, but it surely was undoubtedly capable of remedy the SLA resin. The used resin was common eSun Standard Resin.

Afterwards it’s a must to do the standard SLA post-processing, together with cleansing off of liquid resin – each the half and fiber – and curing the half. So far outcomes are fairly first rate, with overhangs nonetheless being a weak spot that will likely be addressed in future revisions.
