So, it seems we are going to be build 3 Prusa I3 printers sometime in the future.

This page is an attempt to document it all, our own little BOM. (bill of materials)

Partslog

FINALLY TOMORROW we are going to order moar parts :D

Belts & Pulleys;

Bearings;


And maybe 5 moar motors for TallOak? :) Oh! and a load of plastic :D

So I've started printing parts, first 3 sets, but now maybe 4...

Also, i've bought the spare motorstock from the0, 10 pieces of Wantai motors for 100. We still need 5 extra (Dupe doesn't need motors)

And we got a 4pi from Kliment (and some 624 bearings) for 100 euro. This is ment for the Fablab.

Regarding smooth rods, it seems profzon could still deliver them but is way too busy to do so now, so we will have to look elsewhere. He _is_ able to provide the M5 threaded rod and M8 nuts&bults and will do so ~quickly

Participants and Printer Plans

We have 4 participants in total.

Fablabwag

Stretched i3! 21x27x30cm printarea.

  • Smooth 8mm rods; 2x 48 2x 54 2x 56
  • M5 threaded rod; 2x 54
  • Jhead 0.4mm 3mm filament

4pi electronics, and a raspi with octoprint. <-- already ordered

Laafwerpen

Special remix with foldable Y axis

  • Smooth 8mm rods; 2x 47 2x 57 2x 56
  • M5 threaded rod; 2x 54
  • 2x Jhead 0.4mm 3mm filament
  • Arduino + shield

Tall0ak

Totally stock i3, using the Arduino 2560 that Tall0ak already has.

  • Smooth 8mm rods; 4x 47 2x 41
  • M5 threaded rod; 2x 39

Dupe

Single framed i3

  • PSU
  • smooth & threaded ... Length??
  • nuts & bolts
  • bearings (LM8UU + rest?)
  • belts & pulleys
  • endstops
  • fans

Needed

power supply

Currently i am using a 12V supply for everything, but it is quite possible to heat the bed on 24V and run the motors on 12V. Maybe

40 euro

hotend

I don't see any reason to not use a J-Head.. 0.5 is fast but i might follow ID and profzon and go for 0.4..

60 euro

hobbed bolt

Arcol's hyena is awesome :)

15 euro

electronics

No idea yet.. Maybe go for 4pi?

Or this thingy for cheapness?

stepper drivers

Provided we are _not_ going for 4pi, we need some. Stepsticks should be fine.

stepper motors

They cut us a deal earlier, maybe we can try it again?

55 euro

smooth rods

Not sure, maybe profzon has an idea about this?

Stainless: http://www.fnf-metaal.nl/roestvaststaal/leveringsprogramma/rvs-staf http://www.rvsland.nl/Webwinkel-Product-5856865/Staf-RVS304-%C3%98-8-mm-H9.html

Typically ~3 EUR per metre. ~3m per printer (not including inefficiencies etc.) ~10-15 EUR. TallOak (talk) 15:09, 29 January 2013 (CET)

20 euro

threaded rods

We have a shitload of M8 threaded rod on the space already, we _will_ probably need to get ~5 meter of M5 rod.

10 euro

nuts & bolts

Again, not sure... profzon?

10 euro

bed heating

I would like to maybe experiment with a different sized bed, seeing as this is available for not much more money.

30 euro

build surface

Piece of glass from the neighbours? Or maybe finally use that piece of scanner glass i've been saving.. hmmm

5 euro

bearings

10 LM8UU style and a couple of 608 and maybe a 624?

We have some 608 floating around in the space ...

6 euro

printed parts

Yes yes

belts & pulleys

T2.5! So ...

Or;

25 euro

endstops

2 euro

fan

2 euro

frame

Right, choices are to be made. Which wood, if wood at all? Boxed version? Single plate?

Boxed version;

  • Some wood

20 euros?

Single frame;

  • milled/waterjet piece of alu?

80 euros?

Total

280 euros , missing electronics 300 euros for boxed version, missing electronics
360 euros for single frame version, missing electronics

Wow, really 280? This can't be right :P Ah, missing the frame.
