Filastruder: lets start assemblying!

Finally the filastruder kit arrived, and we are really curious to build it and see if it's th solution to our recycling problems. It comes with a sticker with the serial number to attach to it, a nice touch I have to say.

 

Extruder version 1.3 instructions version 1.3

The pieces are in various bags but determining what is what is not that simple.

You must print some pieces with a 3d printer but obviously if you want a filament extruder you already have a 3d printer, otherwise what would you need an extruder for? We chose to print a different version of the hopper, found on thingiverse

The instructions come with very nice diagrams instead of photos, and being a naturalist I'm partial to diagrams because they usually are much clearer than photos. You can really show the pieces better in a diagram, but in this case there are too few illustrations and some of them leave doubts.

The instructions are fairly clear, but I always have problems with some of the “big words” so here are some pictures of the various steps to help you out through the process.

1) Collar on feed screw, we are moving it near the black coated part

On the other side the collar we used a vice to screw it and a Dremel to grind the lips of the barrel

2) the instructions say you have a bearing, but we had to assemble it from 3 pieces in 3 different bags

We also found out some steps after that the bearing was off center so we added some kapton tape to have a better fit, though on the website it states it's not a problem even if it's a little bit loose.q

5) now you should add the hopper body but we printed out a different version in 2 pieces so you can add it aftewards

7)the heating band in the following diagrams is a little more clear, we installed it with the cables pointing backwards

8) and then the brass nozzle

9-11)time to add some more wooden pieces and the spacers on the bolts

12) tightening by hand the screws on the wooden piece

13) now this step is interesting: you use a dowel pin to connect the motor to the auger, but you need to add a couple of small metal tubes to make it fit nicely. In the diagram you only see one so here you have more pictures.

Check now if the setscrew in the shaftcollar is too tight preventing the auger from turning, we had to loosen it and tighten it again after this part.

15) attach the motor to the wooden piece, the piece is not simmetrical but placing it next to the rest of the assembled pieces we think this is the right orientation, with the largest piece of wood underneath

16) wrap hot end in provided insulation (note!!! Wait for this step, it will be easier to do it after placing the sensor, otherwise you will have to open it up again)

17) get your wooden base (not included) and start drilling!!

21) now you have to attach the angle brackets, the instructions don't state it but it's useful to add a washer otherwise the bolt will ruin the bracket.

22) line up everything and again add some washers

26) filament guide: uses washer, nuts and bolts around a copper piece but the provided screw is too short.

 

And that's the end of the mechanical assembly, not bad you can also have a look at these videos on youtube.
