We thank you for your business!!


Filastruder Enclosure V2


We have finished revamping our filastruder enclosure. Here is what we have changed:

One of the biggest changes is the guide assembly. It is now a single printed part that mounts to the front support. It uses a 50mm fan instead of a 80mm fan. It also uses a single guide. At 4ft and using ABS, we got great results and holding tolerences of +-.05mm.

We added a spine to the enclosure. That makes the overall enclosure more rigid. This will help with the newer motors additional torque and allows for operation without the back panel.

The supports went from 1/2 ply to 3/4 ply. This prevents de-lamination of the plywood from the threaded inserts.

We have added two T-nuts to the spine. This allows for the machine to be wall mounted using two 1/4-20 bolts.

FilaWinder only $179.99
We have started selling the FilaWinder. A fully automated filament winder that utilized a feedback loop to maintain high filament tolerances. This is great for people who want their filament operation to take up less space or don’t want filament coiling on the ground.

Vapor Print Finisher
The Vapor Print Finisher(VPF) is a hotplate that can be used to perform acetone vapor baths. An acetone vapor bath uses acetone vapors to smooth out a 3D printed ABS part. Giving your prints a smooth glossy finish. The VPF is small and compact and gives you the freedom to perform vapor baths in well ventilated areas.

Masterbatch Ratios for the Filastruder

Great work by David Smith using our plastic and colorant.

Bits Into Atoms

I’ve been mixing up different colors and running them through the Filastruder. I’ve kept the Filastruder going 100% of the time. I’m trying to do them in an order so that the colors are similar and that one batch can quickly transition to the next. Here is what I’ve done so far.

Lemon/Lime (1:64 master batch ratio) – The color came out very close to a nice lemon lime color. The color varied back and forth between green and yellow as it would hit one of the master batch granules.

  • 2 cups ABS Natural from OSPrinting
  • 1.25 tsp yellow master batch
  • 0.25 tsp blue master batch

Yellow (1:32 master batch ratio) – I wanted a color that could be used to print a Pikachu for my daughter. For a true Pikachu yellow, I probably should have added a tiny bit of red to it. The yellow came out nice although…

Fully Assembled Manual V1.2 Released

The newest version of the manual is out. We have changed out a few parts and how we assembled the fan assembly. The 3D printed bars have been changed with laser cut ones. Also, the fan is placed under the fan mount. This allows better adjustment of the fan assembly and prevents the fan from blowing on the nozzle. If you have the printed guide bars, here is Manual V1.1.
