Battling the Dreaded Injector Bobbin Prints

So this is like my 4th style attempt at the 13 Cavity injector Bobbins.  The dual filament model is basically untested, do to some kind of Slic3r glitch, and not having the right printer completed.:s:P
The side prints don't turn out very well, if they do at all.  I have another model I need to post that has glueable fins, but is difficult to line all of them up.  After researching measurements and layer height, I realized the fins may be inaccurate anyway.  So I came up with all this:

https://www.youtube.com/watch?v=jRnzOneFbhc


https://www.youtube.com/watch?v=4kjIL2EcgfI

I really like how the 0.15 layer height turns out.  It makes the parts look like they are almost injection molded when looking at the side.   Why didn't I try smaller layers sooner. :dodgy: lol

Nate

Oh, and a side note.... there would be 432 total layers on the bobbin when assembled. :cool:  Just sayin.. :D:D

Interesting idea to use the 3 D printer. I always use my cnc lathe and I would like to compare material costs.

So there is my question: what is material costs for a single bobbin?

I have in mind that 1 kg of the plastics are round about 90$, right?
so weight of the end result bobbin should give the costs.

of course for overall cost calculations the cnc printer and the cnc lathe should be included but for now I would like to know material costs.

thx in advance

The filament I've been using in this project is from Ultimachine.com, $75 for 5 pounds with out a spool.  If you order with a spool it costs $86 dollars.  I will be ordering with a spool from now on so I'll use the $86 figure as worst case senerio for natural color ABS.  If my math is right that comes to $1.075 per ounce.  
I added up all the parts printed to build the bobbin in these videos and ended up with 6.7 oz, including the jigs for glueing.  This is also including the small sheets of wax paper, since I can't remove them yet.  
So ABS material cost is at about $7.2025.  But if you want to consider everything needed to print these, there is also Acetone to clean the bed, and super glue which isn't much at all.

Colored ABS is also a little more expensive.

Wow, that´s cheaper than delrin raw material used for the lathe.

thx and good luck for your progress!

That is Amazing work ,

Just found this thread..

Do you have a website ?

Can we work together more on these

Like to order some Dan

I do have a website www.firepinto.com that I haven't updated in a long while.  I don't have anything set up for selling as of yet.  These are rather time consuming to print, and I only get weekends to work on printing if I'm lucky.  I have other projects to finish up before I begin selling anything again.
  This is completely open source though, so you could find anyone with a 3D printer that will print them.  Just make sure they print at 0.15mm layer height and keep their Z axis homed to 0.15mm from the bed surface.

Ok well I will promote info best I can
as all things take time even organising info ,

 if you end up making  basic pcs , even just the fast ones
I can list generate orders for sure.

time will tell, I can see a lot of work into each bobbin. so it will save other time
for sure.

maybe one day it will be faster as practice makes perfect no doubt others are trying to help and learn as fast as they can etc

 for now I will list info pending further
 improve on all areas as time goes by .


 I will start to build website in best way I can
to clarify all info into sections for fastest uptake by public,

every one is invited to send pcs parts or price
for what they can source or provide ( even if it is just relaying from other companies and a 5-10% mark up it all heps get parts to right people.

Also help pay for their time and labor separate and anonymously  

 I will list there as a broker point
, as it is separate from here. As here should be open and free for people who want to try it them selves.

Keep message crystal clear open source.!!!!
free is best ,

but if we are laboring on individual parts as a collective it can help speed of uptake a lot, for example cut 20 square instead of one and sell 19 just above cost,
and every one wins. as uptake is faster . if we list on  other sites.  

So I will do my best to save for producers on  the market and product promo.

any way every one can

just send want you can to to danieldonatelli@hotmail.com
and I will list here www.securesupplies.biz with no names on it.
they may be multiple suppliers for 1 single part that is the idea!!
a industry starts cool...  

so we can get some movement going and ease pressure
on certain areas of the massive information monster .
for every one.  

starting to be excess and a mess and flounder in some ways.

All good I guess

anyways Love the bobbins stan would be  proud.

send what you can do or offer.

I took some pictures comparing Russ' machined delrin bobbin with the modular printed bobbin.
 [attachment=3748][attachment=3746]
They are extreamly close to the same, they even fit each other!  Russ does some fine lathe work!

Sweet! Did you start gluing yet?

Nate
Well no, I thought I had some glue, it was a solid blob and hard as a rock. I'll have to buy some.:huh::(:blush::D

Say Nate, did you say you were using Marlin now? How did you get past the PID. Also, what steps do you have set for your Z axis and are the lead screws 5/16 x 18 or are the metric?

Yep, I finally tried it out.  There was a line that needs to be commented out by putting // in front of the line to disable PID.  I'll have to check what I have for settings when I get home this weekend.  The printer I tried it on is all metric, so 8mm threaded rods, I don't know what pitch thread that is.  I still need to do a final calibration on all axis.

I also noticed the heat outputs flash on and off now.  I'll have to find a way to change that when I put it on my 120 volt beds so I don't have to hear the clicking relay.

You have any ideas for a low RPM 12 volt motor?  I think I want a motorized spool holder.:D  I might just draw it up for a nema 17 stepper but its kind of overkill...

You could use a car electric window motor with the gear box, then just control the speed with a rheostat. So the printer you first built is it up and running ? What was the step settings for it, as I think you used 5/16" x 18 threaded rods for the Z on it ?:D

Well I ended up ordering a couple of these: http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_253500_-1

I plan on using a microswitch that trips when the filament tension gets snug.  
Right now I only have my lulzbot up and going.  I had to take down my other printers and put them in storage for a bit.  If I have time this weekend I'll be pulling my first one back out to get running.
