Hello, I am new here and have spent some time looking at the RepRap project. While looking at what parts are required, I was wondering how people procure the parts for the extruder as most people don't have a lathe. Is there somebody here that makes these parts? Since I am very interested in the RepRap project, wouldn't mind having a RepRap, and have a machine shop, I am willing to make the extruder parts...if there is some interest. I already spec'd out most of the materials and figure I could make the parts kit (barrel, nozzle, bearings, feed screw, etc.) for some cash or some sort of trade. (i.e. Somebody sends me some RepRap parts I need and I send them the nozzle kit...at least until I have all the parts to build my own RepRap.) What does everyone think? If there is some interest, I'll build 8 kits and see where it goes from there.

I am still here making parts and have a small inventory of them. Here is my latest thread: [dev.forums.reprap.org]

The new design takes fewer machined parts and uses a pinch-wheel design. However, If you really want the old kit (as this thread was for) I still have some parts for it. I would highly recommend the new kit, though. (The thread for the new kit is at: [dev.forums.reprap.org])

Brian

Unfortunately, I don't have any darwin printed parts available. I have been thinking about making some parts out of acrylic, plastic, etc.; but, I haven't had a chance to look closely at the files.

Sorry about the late reply.

I still have some extruder parts kits and, if there is enough interest, can make as many as required.

The parts kit, that is available, is for the direct-drive version of the extruder 1.1 (http://reprap.org/bin/view/Main/RepRapOneDarwinThermoplastExtruder).

However, I can make parts for the newer version, if there is interest.

Are you still building the parts kits? I just recently came across the RepRap and have become quite interested in building one.
As I live in Australia I would have to buy the kit as it seems a long way for a 2 way transfer.

If you're still active, how much to send a kit to Aust and how soon.

Cheers

Hello,

If you would like to go the geared route, I do have those bearings as I made almost 30 of them by following the directions for the cable-drive extruder.

However, unless there is a big advantage to using the geared system, I would avoid any unnecessary complexity and use the system Wade and Nophead are using...at least until somebody builds a better extruder.

Brian]]> reifsnyderb For Sale Mon, 12 Jan 2009 16:34:59 -0500 https://reprap.org/forum/read.php?94,18969,20293#msg-20293 https://reprap.org/forum/read.php?94,18969,20293#msg-20293
You can see it here:
[objects.reprap.org]

and here with Brian's parts inside:
[builders.reprap.org]

So far so good! If you want to go the geared route, be aware that it covers up the second output shaft on the motor, so you'll have to come up with another way to measure the shaft speed, or just go open loop.

In order to make it easier to figure out exactly what is in the parts kit, I have posted the parts kit information in it's own for-sale posting and linked to this post.

Here is the new post:

I just discovered that an extruder requires 2 half-bearings instead of the 4 that I have been sending out. Therefore, I am now sending the kits out with 2 half-bearings and reducing the price to $31.00. I'll send out 4 half-bearings, for the old price of $34.00, upon request.

All new drive screws will also have an extended lower bearing journal in order to allow for a looser tolerance in the plastic extruder housings.

The parts you describe are almost identical to what I am selling in my kits. I did notice that there was a note to chamfer the PTFE...I will see if I can do that to the next batch as it appears to be a good idea.

I am using brass rod stock to make the nozzles...not M6 dome nuts. My nozzles have a 0.4mm hole, are slightly less than 8mm in diameter, and appear to have less brass than the dome nuts. They may heat up faster. I really don't know as I don't have any feedback yet.

The brass heater barrels, I am selling, are 45mm long and have a milled notch at 36mm, for a thermistor. If you don't need the milled notch, it shouldn't make any difference. You could put the notch on the side of the PTFE, for example. I also run a die down the threads, as a final step to clean-up the threads, as the threads do get slightly damaged from holding them in the collets. You shouldn't have to worry about filing them flat as they are cut-off in the lathe.

Here is the individual price list in US dollars:

M5 Drive screw: $8.00
PTFE Holder: $5.00
Nozzle: $6.00
M6 Brass Heater Barrel: $8.00
Half Bearings for Drive Screw: $8.00
M5 Nuts: $0.10 each.

Shipping and Handling is $10.00 for anything up to 5 kits. If over 5 kits, I'll make up an individual quote.

M6 threaded brass rod is available at McMaster-Carr (http://www.mcmaster.com) for around $17.00 for 1 meter.

If you would like to order the parts from me, please send me a private message, including your address, and I'll send you payment information.

Regards,

Brian
