Title: Thinking about building a 3d printer, Prusa, check the links. Updated 12/14/14
Post by: Jeff Nading on February 27th, 2012, 02:38 PM
You will find good pricing on many of the items here, or search eBay to find them.
First thing to think about, I would suggest not buying kits without the use of linear bearings, the reason, you will not see the desired resolution on the 8" = 200mm x 8" = 200mm print bed.

I would also buy from these people.
http://www.tridprinting.com/

1. Electronics:
Here's what you will need :
Arduino-mega-2560, Ramps 1.4 with 5 stepper driver boards, Display board with cables and adapter board, wiring, fan, heated bed, thermistors, sd card and sd card reader, GT2 pulleys and belts and end stops.

2. Ramps 1.4 adapter board, plugs into the Arduino Mega 2560 board
included in electronics kit from above.


3. For the Pololu A4988 stepper drivers, you will need four for the Prusa, Rostock and Kossel Delta, need to make sure you also get the heat sinks and heat dissipation tape for the drivers,

4. SD card and adapter, most are built into the display.

5. Thermistor 100K for temperature sensing, buy at least four.

6. GT2 pulleys and belts:
Do not buy plastic pulley's, as they will crack and break, make sure the belts are long enough for your build.

7. Stepper motors:
You will need 5 for the Prusa and Mendel Max printers, 4 for the Rostock and Kossel Delta 3d printers.

These Dual shaft stepper motors are the ones I bought.
http://www.alltronics.com/cgi-bin/item/N1728D63/55/OSM-NEMA17-Dual-Shaft-2A-83oz-in-Stepper-Motor

8. Hotend , I built my own completely, I did not buy a kit, although I did buy peek and ptfe rods [expensive], I made all of the parts with the use of my lathe.

You can buy them here, J Head style
http://www.ebay.com/itm/like/321454746057?lpid=82

you can buy the element here
http://www.ebay.com/itm/261178943188?ss ... 1423.l2649

9. Endstops your choice of mechanical or hall effect, you'll need three,

10. Motor shaft Z axis couplings, buy one for each side of the Z axis, total of two for the Prusa and Mendel only.
http://myworld.ebay.com/nrg24seven/

11. Bearings: Buy 10, 608 Skate, sealed if possible and 12, LM8uu linear bearings, for the Prusa, I did grease the linear bearings.

12. Heated bed plate

13. Power supply:
I have found a power supply that will run the printer completely, heated bed, hotend, all electronics and steppers.
Google this, Power Edge 2850:
Specs:
Dell NPS- 700 ABA
Input 110 V AC
12 volts @ 57.3 amps
3.3 volts @ 5.2 amps

You can find them on ebay

Here is how to wire it to make it run:

http://www.rcgroups.com/forums/showpost ... tcount=450

You could also install a potentiometer, scroll down to post #461 here,
http://www.rcgroups.com/forums/showthre ... 09&page=31


14. Other items such as screws, nuts, bolts, 7.98 mm diameter, 8 mm smooth cold rolled steel or equivalent drill rod and 8 mm althread rod, you can purchase locality and will need to know lengths and size of each.

I recommend not using SAE 5/16" x 18 althreaded rods for the lead screws
Here is why:

16. http://www.kaptontape.com/1_Mil_Kapton_Tapes.php

17. I bought four 25' spools of red, black, green and blue 22 gauge wire to splice into the stepper motors to lengthen their wire, but all wiring except for the power supply is included in electronics kit from above.
I also ran all the stepper motor, and opto wiring in heat shrink tubing, separately of course.

Software needed:
https://github.com/kliment/Printrun
http://arduino.cc/en/Main/Software
1. Arduino
2. Marlin
3. Pronterface
4. Slic3r

 Then if you want to design parts you could use Google sketchup, Blender or what is used here http://www.thingiverse.com/popular/page:2

I just found this hall effect end stop called hall-o:

http://reprap.org/wiki/Hall-%CE%98

I like the idea of adjusting via potentiometer for the Z axis.  Time to make a parts order.:)
Slic3r 0.7.0    http://slic3r.org/

Major new features:

   * a new rock-solid slicing algorithm, based on a topological approach, able to   process efficiently a wide range of STL files without any warning
   * generation of support material (optionally, with a second extruder)
   * cooling and fan control
   * ability to read the AMF format


Looks like Slic3r can do supports with dual extruders.:cool:  I'm going to have to look into that.

That looks very promising Nate, I added the hall effect endstops to the parts list up above, they carry them @

I didn't think to look there, 13 bucks is pretty cheap.  I'd probably pay that in shipping for components from china.  Just put a order in.  You see that they raised PLA prices?  Kinda sucks.

Yes, I saw the prices, there is such a demand for pla and abs, I think I am going to build a machine to extrude filament. I am mostly using abs now, works well.

Might be worth a try, but I have no problem with adhesion, using the kapton tape, gears are the hardest parts to release off of the glass with the kapton tape on it :D.

It looks like a good price for an assembled board.  Ultimachine sells them at the same price:

I saved 20 dollars by going with the DIY kit with pre soldered SMT components:

You will also need a minimum of 4 stepper drivers, 5 if you will be using 2 extruders in the future.

Haha well crap! Lol Jeff, you may want to ad that on the first post! Lol much eazer! ( geting over whelmed here lol)

is there a hard were kit also? With SS rods?

Looks like the slide berings come in a 12 pack? Or is that 1 each? That eBay post is confusing.

Thanks guys! Want to build this thing!

Thanks to Jeff for the huge jump start!!!

Can I not just add hot wires to the AL plate you made Jeff?

~Russ
It looks like a good price for an assembled board.  Ultimachine sells them at the same price:
http://www.ultimachine.com/content/ramps-pre-assembled-kit

I saved 20 dollars by going with the DIY kit with pre soldered SMT components:
http://www.ultimachine.com/content/ramps-diy-kit

You will also need a minimum of 4 stepper drivers, 5 if you will be using 2 extruders in the future.

If you haven't already bought the Mega board this kit comes with everything:

Haha well crap! Lol Jeff, you may want to ad that on the first post! Lol much eazer! ( geting over whelmed here lol)

is there a hard were kit also? With SS rods?

Looks like the slide berings come in a 12 pack? Or is that 1 each? That eBay post is confusing.

Thanks guys! Want to build this thing!

Thanks to Jeff for the huge jump start!!!

Can I not just add hot wires to the AL plate you made Jeff?
~Russ
Russ I'll email you some photos of what I did to make heaters for the aluminum plate.

Ok, or just post them on a new thred? "heater plate" or you may allready have a thred on them?

I'll need to look over that SS rod thing as I know you had mentiond that before.

I just hate getting the wrong stuff!!! Lol

Thanks!!  ~Russ

That is an excellent looking machine Tinman!  It looks like he was building a cnc router.  It should be fairly easy to convert it to a "Repstrap".  I would gut out all the old electronics and replace them with an arduino with a RAMPS sheild.  Im pretty sure the stepper motors can be used, just have to sort out which wires are needed.  The smaller motor looks like it would work for a geared extruder too.  Then you just need a bracket for the extruder and a way to heat the bed.  It has all the limit switches for the Y axis, I couldnt see if there is for the X and Z.  
That would be a monster reprap. :cool:  It would print a little slow but it could print your next printer.:D  Once it is running on RepRap firmware, I would also set it up for PCB milling which it would work extreamley well for.

we can do 400 steps instead of 200.

thoughts?

and is there a setting for 400 steps in the software?

also found these for 12.99 ? same thing? will they work?

Russ, I would really stick with what I know will work. This is what I have used on my last two builds and they work fine, you can also see the specs on them.
http://www.alltronics.com/cgi-bin/item/N1728D63/55/OSM-NEMA17-Dual-Shaft-Stepper-Motor  
I'm not sure the driver boards will work at 400 steps per revolution, there made for 200 @ 1.8 degrees per step. Also the shaft length is important, longer the better. The one on ebay I think would work. You'll just have to cut a flat on the shaft, to lock the gear in place.

Hi Geert, I knew you taught and knew it had to do with 3d graphic's and software of some kind, but did not know what exactly.:D Also, the meaning of what I was trying to say was, [and said it very poorly:blush:],  with me seeing your build of the 3d printer, just added to my realization that this and all that you do for us here at the forum and everyone else that you help, the good that you do,  was and is a very a good thing. Giving is better than receiving. Didn't mean anything else but the fact that you are a great and kind person and enjoy having you here on the forum. :D There are many other's here, who I could say this about as well.
I have not been to Keshe's forum in about two weeks and didn't know there was a work group there now. Thanks for telling me, I will check it out, let me know If I can help with your 3d printer build, your friend, Jeff.:D:P

Maybe a dumb question here but  Can a 3d printer handle a square feedstock?  The round shape forces the use of extrusion process.  Just thinking out loud  but maybe a square shaped stock could be molded into lengths then joined together.  Also What types of plastic items would be best to collect for those doing the recycle?

Square stock filament could be used, but the problem I see right off the bat is you would have to modify the extruder. Another would be one of storage, it's so convenient to have long lengths the filament on a spool, 2.2 lb's worth of filament, doesn't take up much space either.
Would also take time to splice lengths of filament together, say if you were in the middle of a print, it would not be a good thing, when one has to splice filament to continue a print.
The plastic most commonly used for 3d printing is ABS plastic.
Most old tv's, computer monitors, stereos, paper printers and so on are built with ABS plastic, could be recycled into useable plastic for 3d printing.
Hope this helps Blazer.:D

Thanks Jeff but my thought was to mold it into a sheet then run it through a slitter.  The sheet could be made as long as we want?  The sheets would be say 6" wide and coiled like steel coils prior to the slitting process, then put on to the 2.2 lb spools.  I also believe quality in regaurds to thickness would be simpler.  Thanks Dave

Thanks Jeff   For 3mm my math indicates .1047" x .1047" thick and width.  Since I have 0 experience with abs or pla and still unsure of its properties when heated anything will be a best guess.  Most of my experience is with expandable urathane products.  I am thinking pouring melted abs (600 F) onto 6" wide solid base mold, add a top piece then compress with a series of rollers to the .1047" spec. +/- .004.  Cool down, then coil onto a roll or possibly move it to a slitter process while still on the base.  Length would be dependent on space and resources of course. A  6" wide may yield up to 50+ lengths of filiment. The ultimate goal of course to provide a low cost simpler process to produce a good quality filliment.  Any thoughts or input are appreciated.  Toxicity? Demolding?

I measured my 3mm filament, it comes out to be .1125" dia.. The print temperature of ABS is 230 degrees C., Don' really know what it would be to melt a batch the size we're talking here.
I can pretty much stay in the same room while I am printing something, but again a batch this size, I don't know about the toxicity level.
What do you think about a teflon coated mold for demolding agent, you could use the same mold over and over this way. We use this in aircraft, you can buy it in liquid form and spray it on like paint. Don't know the cost of it though, I would imagine it's pricey.
Anyway it sounds like a plan :cool::D:P.

Been a long time since I've been around but... My co-worker purchased a 3d printer (foreign knock off of maker bot, I think he said CDC brand?) and has gotten me thinkinking about them again. I remembered there was a few of you on here that had them. I was looking at doing something with the "replicape" if any of you have heard of it. It takes the Beagle Bone Black and instead of using shields like you do with arduino and raspberry pi, it uses capes. This cape comes with drivers for 32 micro stepping and pwm for heaters, inputs for end stops etc. Anyway, the price of the replicape isn't cheap but since you're able to easily integrate it with a beagle bone black, this makes it so your printer has a full fledged GUI. This makes it easier to design slice and print from one machine. Thoughts?

I would like to build a Rostock 3D printer. Can some one tell me if these would work?

http://m.ebay.com/itm/291184578609?nav=SEARCH

http://m.ebay.com/itm/300987383770?nav=SEARCH

Are there any drawbacks to any of these parts? Also, how hard is it to remove the print head on these? I would like to make a sharpie adaptor to print pcbs for etching. And is there a way to turn off the hot bed for the purpose of printing pcbs? Any help is very much appreciated.
Thanks.
Title: Re: Thinking about building a 3d printer, Prusa, check out the links. Updated
Post by: Jeff Nading on July 14th, 2014, 04:35 PM
Hi Jamie, the second option is just way to expensive for the Rostock, the first is much better, but I don't see the hotend included. The Rostock only uses four stepper motors so you will only need four stepper drivers as well. The SS rods look a little short as to the one I am building right now, but will work with the length of belt they are offering with the kit, just depends on how tall you want to print an object or part.

You will need wire and connectors, Arduino board, ramps board, four stepper driver boards, heated bed, four stepper motors, three endstops, six linear bearings, seven 608 bearings, six SS rods, six yoke rods, belts GT2 type three GT2 pulleys, hobbed tube for the extruder, teflon tubing, Power supply, zip ties, LCD, SD card and reader, hardware and just a few other things. I really don't see any other drawbacks to the first kit, just know upfront there will be a cost to all of this but prices have come down. To give you an example, two years ago I bought a ramps board for just under $200.00 and I had to put it all together, I can now find it for $20.00 already to go, so these items are coming down in price. I just uploaded this video to show the progress I have made.

https://www.youtube.com/watch?v=u1Qi93Lf46M#ws

The part you are talking about to print PCB to etch them is found on thingiverse and it's very easy to remove the hotend to install this printed part to hold a sharpie, I have printed these myself. On the heated bed all you do there is not turn it on, or you can install a switch to turn it off.
Jamie if you would like I can send you all the updated links to buy parts cheaply for your Rostock build, just PM me your email and I'll shoot them to you, Jeff.

With all of the links you have sent, i can compile a parts check list and start ordering in little bits. I can see from some of the older links above to the newer links that a lot of this stuff has come down in price considerably which really helps me out too. Those new links you sent will help me figure out the most economic way to order parts. I really appreciate you going out of your way to help me out here. I hope one day i can return the favor.

Well I really don't have a recommendation on any books, I'm sure there are some available. Most every thing you will need is on this very thread as far as parts go, any knowledge you seek, questions you might have, can be answered here as well. If you in fact do see yourself building a 3d printer one day, might I suggest the Kossel Mini, you can build it from a complete kit or build it from scratch. The build instructions can be downloaded in PDF format here

and here's more information on the wiki

That pdf was very detailed!
was exited just reading thru. :excited:

The build itself looks like something I can manage as long as I stick to the instructions.
The arduino im assuming the programing would be open source and just copy and paste?

Maybe the mayor hurdle for me would be the actual design interface. going from drawing to print.
last timeI I worked on computer drafting was back in high school many moons ago!

I must say this is a very powerfull tool for anyone in these forums.
bieng able to build your own parts thats just pricless!

Thanks again :thumbsup2:

What you could do is, just buy the ABS plastic parts kit on eBay then go from there with the parts listings I have posted in the beginning of this thread, if your not sure about an item just ask and I'll answer.
Another place I have found very useful is the Google delta forum here
https://groups.google.com/forum/#!forum/deltabot
I also recommend using carbon fiber magnetic diagonal rods and ball studs from Haydn Huntley here

Look at his first post in the thread you can view photos of them.
Most people use Google Sketch up to design with.
Yes building your own parts for vic coil spools and the fuel cell would be well worth it.
