I have a few notes: The lead-in and lead-out angles on the pattern should be more shallow, they look a little abrupt. When grinding, it's best to start at the shallow end and work to the deep end, I think you will find that starting with a lighter load will give better results and grinding disk life. On a lathe, what you call the X axis is referred to as the Z axis and what you call the Y axis is referred to as the X axis. When you decide to CNC this thing, that is the nomenclature you will find used in that domain.
I've downloaded the paper - unfortunately, all the links listed are now "404". Hopefully the authors will make the 3d printed parts files available. I think with some changes, this design will easily create multi zone extruder screws (using different profiles) of sufficient length to produce vastly improved DIY filament extruders. The paper mentions a limit to the diameter of the screw stock of 16mm dictated by the jacobs chuck holding the material - a simple bit of lathe work on the end of much larger diameter rods will make a 25mm rod fit into a 16mm chuck! :)
awesome video! Have been struggling for weeks with making an extrusion/compression screw, CAM programs are not friendly to extrusion screws being made on a CNC machine with a 4th axis! We will definitely be in touch
Hi! If such a screw were used for a filament extruder, how many cubic centimeters per second would it squeeze out plastic? Is there a relationship of melt volume to screw diameter and groove depth?
Hello and greetings from Istanbul. For a while , I have been trying to find an affordable way to produce extruder screws without a lathe, as I can not afford to buy a lathe or hire by hourly use. Your system is just for me. I need to know one thing: What is the formula to determine the rpm of screw and the sliding speed of the set up that grinds the screw. Thanks
if you build this, you actually WILL have an affordable lathe and the skills to use it! I think that if you can afford it, there are some obvious upgrades to make. The Z-axis bed could be lengthened but would need more structurally rigid rods to run on (drill rod perhaps?) As well, the profile can be changed at will by simply changing the profile template. Good luck! Istanbul is a lovely city - dodgy taxi drivers, but a lovely city with nice people! :)
Hello Joshua, I'm having problem to understand the freecad parameters, could you provide the 3d model of the chuck and threaded rod pulley and belt, please?
Hello Marco, What problem are you having with the freecad parameters? The chuck I used did not have a manufacture provided cad model. I can do a rough model of the chuck if you need it. The threaded rod pulley and belt are both in OSF as OpenSCAD files named accordingly.
Hello Brett, All files are located in the OSF repository (osf.io/ev6ta/). Just a reminder the grinder mount may need to be redesigned if using a different angle grinder.
@@jacobfranz9372 i found it in a jumble of items iv made a step file. Where did you get the pully gears from as I can only find the scad for cnc driver file
@@jacobfranz9372 i designed a jig for the size screw i need. Just been looking for the pulls so I can finish of off the file so I can start printing companies
Currently in the process of making an improved machine that could make a screw for larger systems. Once finished my company would be able to manufacture drop-in replacements at a fraction of the cost.

Impressive!
Hey Stefan! I expect to see a video about making your own compression screw & filament recycling extruder eventually 😉
This is the next step in diy 3d printing. Being able to create small scale extrusion screws will enable diy plastic recycling into new filament.
A homemade screw lathe with a copy carver attachment, this opens up so many possibilities for the home shop :)
this is BRILLIANT! One thousand subscribers? damn, youtube is a tough audience!

Nice work Joshua. And really nice design.
wauw. impressive
What is the leaning angle for the cut ?
Very impressive design. Thank you.
Have you considered a sintered diamond cutting wheel?
Hello, I have a question,
do you have the stl files for this project somewhere ?
Thank you in advance for the answer
That's genial. I've a question, manual speedness of grinding slide does not affect deepness or distance from spires? Thanks
This is good stuff, thanks man
Hi! If such a screw were used for a filament extruder, how many cubic centimeters per second would it squeeze out plastic? Is there a relationship of melt volume to screw diameter and groove depth?
the project works fine. I want to make this machine. I could not access the part file as STL. can you help me?
Thanks so much for this, mind opener for me, ps. How do I get in touch
Nice build
How did you figure out the teeth ratio between the 2 gears?
Awesome idea dude! thx for sharing ...
Great work! Keep it up!

GENIUS
Bro you are awesome
Excellent!
Brilliant work
Brilliant!!!
Well done!!
Awesome!! 🙏🏻

All CAD here osf.io/ev6ta/
cool, making a hand made auger bit :)
this is a terrific project - unfortunately, the design files link is "404"
pls shar the file for 3d printing parts
Brilliant
Where's the link to the files???
BOM, CAD, Full source code, instruction see : www.appropedia.org/Open-Source_Grinding_Machine_for_Compression_Screw_Manufacturing
anyone out there want to crank out some screws that are drop in replacements for the auger bit in a Filastruder? There's a market for it. ;-)

@@screwwaste9485 SWEET!
@@ggaub what price are you looking for?
@@AS-ug2vq Ideally, less than $100
mat that's some serious shit
great work , but stl files pls
Hi. Nice one. What’s the ration between the two movements???
