Extruded Resin FDM Printing (With Lasers!)

At this level, 3D printers are practically in every single place. Faculties, hackerspaces, house workshops, you title it. Most of those machines are of the extruded-filament selection, higher often known as FDM or Fused Deposition Modelling. Over the previous couple of years, low-cost LCD printers have introduced resin printing to many retailers as nicely. LCD printers, like their DLP and SLA counterparts, use ultraviolet gentle to treatment liquid resin. These machines are sometimes praised for the super-high element they will obtain, however are realllly sluggish. And messy —  liquid resin will get in every single place and sticks to every part.

We’re not precisely what [Jón Schone] of Correct Printing was considering when he got down to convert a basic printer to make use of resin as an alternative of filament, but it surely needed to be one thing alongside the traces of “Are you able to make FDM printing simply as messy as LCD printing?”

It seems you’ll be able to. His extraordinarily well-documented analysis course of is proven within the video beneath, and reveals his design course of, from preliminary thought to almost-kinda-working prototype. As chances are you’ll anticipate, extruding a high-viscosity liquid at a managed price and laser-curing it’s not a straightforward activity, however [Jón] made a unbelievable try. From designing and constructing his personal peristaltic pump, to sending a UV laser by means of fiber-optic cables, he explored a ton of various approaches to creating the printer work. Whereas he might not have been 100% profitable, the video is a superb reminder that not all tasks must go the way in which we hope they are going to.

Even so, he’s optimistic, and mentioned that he has a couple of concepts to refine the design (and welcomes any enter from the neighborhood). This isn’t even the one new and attention-grabbing method to resin printing we’ve seen in the previous couple of weeks, so we share [Jón]’s optimism that the FDM Resin Printer will work (sometime, not less than).

Due to [Baldpower] and [electronoob] for the tip!
