DIY Desktop Filament Extruder #6 [ENG] Bonus: Wood Drill vs. ( Plastic Screw / Compression Screw )

[@jameswiz]

Several things I'd like to say and add.. 1) Great video. Im going to take a lot of ideas for my DIY extruder. 2) A lot of wood bore bits measure hole diameter at the tip of the bit, where they are usually a hair wider, to allow clearance for the auger portion of the bit to remove chips. As for the flex, I don't think that would be a problem and potentially would help to scrape any leftover pieces that get here to the side of the barrel as it flexes more. 3) Plastic augurs are very expensive. I went with a Masonry Hammer Drill Bit, and cut off the cutting tip. This makes a large very heavy duty augur. 4) I went with tapered roller bearings in the rear instead of thrust bearings as tapers ares cheaper, and also offer direction load support and centering.

[@saddlepiggy]

Is the masonry bit’s angle shallow enough to work?

[@glennedward2201]

If you have a lathe you can modify or make your own screw.

[@choiwonseok8371]

Thanks for your video. It is great to choose the screw for making filament extruder. I have some questions 1) how can buy plastic screw? I want to try to use commercial one. 2) if i want to extrude tough materials, what type of screw is good to me? (High frequent pitch or Low frequent pitch?)

[@muhammadsiraj3403]

[@Dougwoz1]

It is so important when demonstrating a particular Device, you should always provide a list of materials, and a link to purchase them. (By being an affiliate to that business you would also collect commission). But in this case the drill is no problem to obtain but the plastic screw is a little harder to find? please provide more information as to where I can obtain one?

[@Werbewunder]

This is a great idea

[@hussainal-sarraf5679]

Good explanation man, After 5 years of your finding.. Do you have any suggestions to improve the Drill wood screw to change its disadvantage to advantage?

[@Werbewunder]

I have tried various drill bits from wood drill bits to masonry drill bits and special drill bits. All have the same problem the geometry is not 100% developed for extrusion. so if you want to make good filament you have to spend money and buy a real screw

[@joemulkerins5250]

Thank you for the excellent video. Yes, screw design is very important for plastic extrusion. There are even a few variations similar to that plastic screw depending on the specific type of polymer that is being used 🙂 Keep up the good work 👌

Hello Ron, where someone can buy compression screw in Europe? Where you got yours from? Thank you

[@en2oh]

Great video. Any suggestions on (less) expensive compression screws?

[@gabrielmonteiro923]

Incredible, i made one in my college.

[@glennedward2201]

Btw if anyone wants an idea thats cheap you can buy yourself a pellet extruder for a Traeger Grill. This would work for a 3d printer sized extruder or a small injection mold machine. Keep in mind many augers need to be reversed to work properly so they would require some type of modifying. A drill walks chips toward you on a right hand move so you’d have to turn it around to optimize the use of the push designed in the blade.

[@glennedward2201]

I personally like the Dewalt DW1687 1”x17” drill auger. Far as wood vs plastic tolerance this is a given. One is considered a precision machine part the other is meant to drill semi accurate holes in wood. Couple considerations. You would probably want to find as close a tight fitting tube as you could. You may also be able to modify the wood drill toward the end by using a high temp epoxy or carefully brazing fillers. All depends how mechanical you are. For example if the tube were to get narrow or more conical, and you ground down the drill to taper it might amplify the compressive push.

[@aaronwright2238]

What heater element did you use and where can I get some?

[@jaimezuleta8125]

Excellent video. Greetings from Venezuela.

[@robbyg3989]

Great explanation! Superb

[@ericstratten6974]

May I suggest that you also share the files for machined parts as STEP files. The STL file format is great for 3D printing, but is a poor format to use as a basis for accurate machining. Thanks

[@JeffDM]

It's best to minimize the amount of "dead space" between the tip of the screw and the die (nozzle). I think you want enough to make sure the plastic can flow to the extrusion die and not much more. Maybe leave room for a "breaker plate" but 2.5cm is far more than needed for a breaker plate.

[@Tamesi1]

Nice explanation, Plastic Screw is much better , One thing is the type of steel and alloy , its better since wood screw would be of carbon steel or less resistance to withstand ware and pressure which at the end may end damaging the barrel if piece is broken while in process. As you mention tolerance in plastic screw is much better, the design is made for non Newtonian liquids flow. Other important thing you mentioned is about the air , some big exturders for other applications have vents to allow air to escape (vented barrel... some have vacuum system to extract air or vapor) , the problem of leaving bubbles in the extrudate is that it may lower quality of filament or may cause burnt material or end product with lower mechanical properties. I really liked your step by step explanation. Congrats!

Hello, did you build the barrel or bought it?

I have a question about the extruding screw is it right as ron declares with the drill bit i always have air inside the filament ? And as next question, how much filament per hour did you think i get whith an auger dimensions 20 x 370mm ?

[@Werbewunder]

If you use a drill that has no compression zone, it will push the air forward. If you have a good drill, it may be that you get little air forward and your filament has few air inclusions. A professional screw has 3 zones and therefore always take them if your financial framework allows it.

[@bearsfromspace]

The wood screw is less than 20mm because that's the size hole it drills, not the promised diameter of the tool. You can see the step near the tip where it becomes larger; this is where the cutting happens, and the rest of the drill is just there to transport swarf out of the hole.

[@Werbewunder]

You're right, that's why she's not as good as a screw, she hardly builds up any pressure. But for testing it is enough later if you want to get better you can replace it

Very good job dear 👍👍👍

[@Skydiverjoe2871]

The wood drill diameter is at the cutting tip and gets smaller so there is some clearance when drilling.

[@Werbewunder]

@Deputy Dawg thanks for your constructive comment! In one point you are right, means the frontend of the drill is wider then the other end. But what i maybe wasnt more clear to show was that their is a curve inside the long distance. This would ruin the whole barrel after a while. Means in the mid on the wood drill was a point which connects to the barrel while the other end was without any contact. The main thing is what i wrote in the conclusion point 1 and point 2 that you have to find first a good wood drill without curve, and then optimize the barrel to this wood drill, so that they fit perfectly together. And because this i wrote in another point that i cant guarantee that they will fit for a platic-screw after it, so that a change from Wood Drill to Plastic-Screw will be without problems. I will try to answer in one of the next videos to it and make a screenshot of your comment to make it clear again. Do you have other questions which can answer in the next videos? Greetings Ron

hi, first of all video really helpful. I want to learn thats; 1) Everything is ready, I will use SDS max drill bit. 35mm diameter, 450mm usable length, and 120mm drill bit back end and back end diameter 18mm. (socket part). reducer output is also 18 mm. Both are the same diameter. What would you recommend me to do? I am just lacking on this subject, and I just cannot make interconnections with AC motor. Its mean i can not coupled with reducer (18mm output) drill bit of back(18mm) 2) I want to learn that; How do I couple a drill bit with a diameter of 18mm the back with the motor? What kind of intermediate apparatus should I use? You know the drill bit is designed for the drill. thats two have different entrances.

[@moretimethanmoney8611]

I'm having a giant urge to build an extruder. I have time, tools and raw materials in the form of scrap metals that I can cast and shape. I have two questions. 1) Is Aluminum too soft to use to make the shaft and plastic screw? 2) Can a couple cartridge heaters fitted in custom barrel collars with a pid controller produce as good a result as the clamp heaters you show?

[@d.t.4523]

Aluminum will not hold the size tolerance needed as the temperature changes. As long as the heat is constant, any heat source would work. Good luck.

For a wood drill it does not have to be long because it does not compact. Try to build in a 3 zone screw instead, you will save yourself a lot of frustration. The nozzle diameter depends on the material you want to use.
