for the past few months, I’ve been designing a new 3D printer digital fabricator for the studio and (finally…) I think it’s time you get to see a little peak at how things are going.
originally, I intended to design a cleaner, more accessible 3D printer for students and artists – but as I was beginning the design, it occurred to me that the primary function of this thing was to move around in x/y/z coordinates.  I quickly I realized that instead of restricting it just 3D printing, there were a lot more possibilities available for studio making if I expanded the capabilities to include multiple kinds of digital fabrication (…hence the name: studio.FAB)  some of the functions I’m including in the design:

  • 3D printing
  • CNC/milling
  • thin material cutting (fabric, vinyl, paper, cardboard, etc)
  • plotter for inks, paints, graphite

now I know a lot of the all-in-one devices fall victim to the “jack-of-all-trades-but-master-of-none” syndrome (I’m looking at the bloated printerscannercopier that’s sitting on Robin’s desk…).  that’s why the studio.FAB isn’t exactly an all-in-one machine – instead, it’s more of a modular design that allows you to quickly and easily (…and I’m emphasizing that quick and easy part) switch the appropriate parts for the kind of making you want the machine to do. for example, if you want to move from 3D printing to CNC milling, it shouldn’t take you more than 10min. to swap out the belts and pulleys for a lead screw.

the studio.FAB is based on the open source RepRap platform.  I’m using 25mm extruded aluminum (t-slot) for the structural framework because it’s more stable and rigid than using threaded rod.  also, I’m designing it with an inverted-T structure (shared by other machines like the Aluminum Mendel, Rook, and Brian Blanton’s unnamed printer) – I think this makes it much easier to upgrade and swap out components when moving from one fabrication method to another (also: easier access to all the parts for repairs.)
one key difference b/w studio.FAB and most of the other machines I’ve seen is how linear motion is handled.  the majority standard is to use a combination of smooth rods and bearings to get smooth motion, but (esp. on longer rods) smooth rods can flex, bend, and get out of alignment. I’ve designed the studio.FAB to use the much less flexible t-slot as the linear bearing.  this is less critical when printing plastic, but can be an issue in subtractive processes like milling.

I’ve been making steady progress, and right now I’m close to having all the core structural elements designed and built.  I’ve had to design all the parts from scratch; even when I’ve had to reverse-engineer some derivative designs that use a different size t-slot, I found different solutions that seem to work better in this design.
once things are in a publishable state, I plan on writing up a pretty extensive overview of studio.FAB – followed by detailed instructions and a bill of materials so you can build your own.  right now though, I just wanted to make sure you got a small glimpse at what’s been happening in the studio for the past few months.

 

definitely more to come…
