Unfold.be (founded by Claire Warnier and Dries Verbruggen) is a high tech and high style design firm in Antwerpen.   They are not new to 3D printing (and in fact we’ve written about them several times).    They share our passion for “frostruding” or in their case 3DP clay-extrusion.      Over the past year they have been busy creating new ideas and exploring clay-extrusion concepts.

Check out their recent post on http://unfoldfab.blogspot.com/.   They are showing several concepts that we have played with too.   The idea of a 3way solenoid valve or a 3/2 way solenoid valve which replaces the two traditional valves (as in MB’s frostruder).     We’ve shown that this works well and can be found on internet auction sites at a very reasonable price (look closely to make sure the pressure flow is directed from inlet -> outlet A on energize and outlet A -> outlet B off energize).   We’ve had a few misdirected efforts.  We also are exploring screw drive extruders as well as multi-extruders.

Looks like Unfold.be is producing clay-extrusion magic.

The most interesting idea that they’ve been working on is object design at a layer-by-layer level (Unfold calls it G-code level design).    While it sounds like a crazy idea to engineers (perhaps a step backwards), it makes real sense for cutting edge design (it’s about control).   The current crop of G-code generator systems (including commercial code) don’t provide much in the way of graphical G-code editing tools.  Further, G-code generators really don’t like objects which are one extrusion band thick.   Thus the idea has some real merit!   Combine, this idea with some point morphing tricks and magic starts to happen (imagine, that each layer has the same number of points then one can apply some point morphing to make amazing shapes).   Further, the layer-by-layer description might even allow self-intersection at the layer level (solid modeling systems are going to frown on any self intersection requests).

Please keep up the refreshing work!

    ben als keramiek student (academie mechelen) gefascineerd door 3d printing. Geven jullie presentaties in Antwerpen?

    What do you mean by “one extrusion band thick”? Thanks!
