3D Printing Small Printers

Everyone loves going large, expanding their D-Bot or HyperCube or Voron or whatever to big print volumes like 300mm, 500mm, or even larger. I'm not really interested in that, I like the idea of small printers! I'm going to call anything with a build volume under a 180mm cube small, and collect some designs here.

FunBot i1

http://reprap.org/wiki/Funbot_i1

Monoprice Select Mini v1/v2

https://www.monoprice.com/product?p_id=21711

  • Build Volume: 120 x 120 x 120
  • v1 is a straight rebrand of the Malyan M200: http://malyansys.com/en/product/m200/
  • v2 apparently has some Monoprice-specific improvements
  • 32-bit control board. Runs G-Code but is closed source so no hacking. Apparently easy to brick while flashing official updates
  • Uses odd stepper (probably 28BYJ-48) for Z so ideal layer heights are weird
  • Many improvements on Thingiverse. Common are filament guide, X axis support, controller fan
  • Active community and wiki

Fabrikator Mini v1

Clever belt arrangement.

Fabrikator Mini v2

Seems like a fail.

MicroCube by Stargrove 1

https://www.thingiverse.com/thing:1938877

  • Build Volume: 120 x 115 x 95
  • Tube frame with H-Bot kinematics
  • Uses 28BYJ-48 steppers but you can upgrade XY to NEMA17

Now this is cool. I'd love to remake this slightly bigger (250mm frame rods) with CoreXY and keep everything inside the frame (except the top Bowden tube) so it can be enclosed and carried, a laptop charger or a 12V 10A power brick would be enough (no heated bed).

DICE by purehektic

http://www.instructables.com/id/DICE-a-Tiny-Rigid-and-Superfast-3D-printer/

  • Build volume: 90 x 75 x 80
  • Laser cut metal frame exactly 20cm cubed
  • MGN linear rails for motion axes
  • Genuine E3D V6 hotend
  • AZSMZ 32-bit Smoothieware board
  • TMC2100 stepper drivers

Pretty incredible no-expense-spared build, though I don't think I'd go this far.

Bukito by Deezmaker

http://bukito3d.com/

  • Build volume: 125 x 150 x 125
  • A Kickstarter which actually delivered.
  • Claims very fast print speed of 100mm/sec!

Proton by Atom3D

http://www.thingiverse.com/thing:2149685

  • Build Volume: 170 x 160 x 130
  • Cantilever arm based around 12mm Z rod and 8mm other rods
  • Open source design

Look at the "distant" direct-drive with the motor on one end, joined by a rod to the filament gear on the other end!

However, after the other Atom3D Neuron delta was such a misrepresented design, I no longer trust this either.

3DR Delta by RichRap

http://richrap.github.io/3DR-Delta-Printer/

  • Build Volume not set, but Richard's is: 65D x 187
  • Delta with 6mm rods and 2020 extrusion towers
  • Open source

Richard has a good video about it here: https://www.youtube.com/watch?v=11PVy4AUbeQ

xxs Delta by Hatsyflatsy

https://www.thingiverse.com/thing:2508671

  • Delta with printed base, doable on 220mm bed
  • Build volume: 80D x 126

Remix of the Sculptr MK1 which I tried to build and failed.

TW Mini Cube by TezDesign

https://www.thingiverse.com/thing:1060267

  • Build Volume: 130 x 130 x 100
  • Proper corexy cube frame on 2020 extrusion

Cranestyle Mini

https://github.com/whosawhatsis/cranestyle-mini

Original is not yet well documented. Walter Hsiao built a modified one here: http://thrinter.com/cranestyle-mini-guideways-version/

nanoCUBE by varykap

https://www.thingiverse.com/thing:555606

  • Build Volume: 130 x 140 x 140
  • 2020 extrusion corexy
  • Outer dimensions 280mm cube

Not that well documented but seems okay.
