Use Filament in your Cube 3D Printer and SAVE HUGE!

Cube 3D Printer bulk filament Usage

The 3DSystems Cubify Cube is a solid little printer. It is very simple to use. There are barely any “knobs” to tweak. It’s good for someone that just wants to reliably print things without babysitting the printer. The ABS does have warping issues even with the heated bed. The big problem is the filament “razor blade” model. The printer is not that expensive, but they charge $49/0.7lbs of filament! (compared to $35/2.2lbs of 1.75mm filament). That’s 5X the price!
I created an adapter which allows you to connect the plastic filament tube and then connect to a spool of generic filament. It was printed on the cube (version 1)

I made a spool holder out of some 1/2 in. cpvc tubing:
  • three pieces of 6"
  • four pieces of 1"
  • two pieces of 3"
  • six T fittings
  • two 90 degree fittings

Using Spool instead of Cartridge

It turns out that you can by-pass/defeat the Dallas Semiconductor 1-wire chip which is located in each cartridge. The chip stores the filament color, remaining amount, etc. 
Put a full cartridge of the same color into the printer. Thread the spool filament thru the adapter and the plastic tube. Follow the instructions to load the filament.
Navigate to the file that you want to print. Then remove the FULL cartridge and replace it with an EMPTY cartridge.

You will get a message that there is NOT ENOUGH FILAMENT. Hit the CHECKMARK to continue
The system will go ahead an warm up the table and then start printing


I tested a roll of 1.75mm white filament ($35) and compared it to the Cube White (ABS) [350166] ($49)
The box on the left was printed with the cube cartridge and the one on the right was with the Octave filament. Other than a slight color difference (The 1.75 Filament is a bit whiter), I didn't see any difference.


  1. Which version of firmware are you running on your Cube? I have 1.09 and I get an error telling me that the cartridge has been changed after I put in the empty one. It forces me to replace the empty one with the full one before it lets me print. Am I missing something?

  2. Have you tried printing with bulk PLA? I have seen a lot of missed steps from the extruder motor with bulk 1.75mm PLA. . .

Happy Monday to you... hope you are doing great today; wanted to share something that was on my heart this morning about MakerGeeks and what’s going on and what the next steps are for us.

Almost 3 years ago we started selling 3D Printer filament(all of it from China) and over the next 2 years saw a booming business come out of those items; reselling filaments from China, Germany and the Netherlands. About a year and a half ago we started with a single extruder and a dream to start making 3D printer filament in bulk scale here on US soil… back then I thought that 1 extruder and me working part time would make more filament than I could sell in a life-time. Well, within just a few months we had bought another extrusion line and hired our first full time operator just to keep up with demand.

Now, surly we would have enough filament to last a life-time; NOPE… in just a few more months we added another extrusion line and lots and lots of overtime and weekends. Now we…
