Ok sounds like a plan. I guess I was over thinking things a bit looking for an easy way out when the easiest way out was just do it. hahaby jabberwocky - Plastic Extruder Working Group
oh i can read anything I have a copy of solid works, turbocad and quickcad(basic autocad) so I an pull dimensions off of a .iges or STL or autocad format. Anything handy.by jabberwocky - Plastic Extruder Working Group
Triffid_Hunter any chance I can get that cad file from you so I can get measurments?by jabberwocky - Plastic Extruder Working Group
It does not have to be in a vacuum the key is to have the atmosphere Inert (no oxygen) It is actually not difficult to manufacture a controlled atmosphere box (a glove box is an example of this) to place the reprap in as everything can be kept at normal atmospheric pressure. The box can be made with plexy and electrical pass through can be sealed with silicone. Argon is probably the best inertby jabberwocky - Plastic Extruder Working Group
I bet we could find a few things in here handbook of water soluble polymers I know that PVA polyvinylalcohol (basically elmer's glue without water ) is soluble when heated in water above 80C so boiling water may work and it is a rather robust polymer. We use PVA as a water soluble binder for our ceramic spray drying formulations at my workplace.by jabberwocky - Plastic Extruder Working Group
I am at that chicken and egg issues in repraping/repstraping of the extruder. Does anyone know where I can buy a kit or get plans for a basic 2d extruder so I can then make parts for an extruder. Thanksby jabberwocky - Plastic Extruder Working Group
Moderators, I did not see if it was acceptable to advertise or put up a job posting on the forum. I am looking for some good engineers (Materials science) and though that the reprap community has the drive and intelligence that we would be looking for. As I know I love the reprap idea and comunity of DIY and am building a repstrap myself. I did not want to post a position without asking if thisby jabberwocky - Administration, Announcements, Policy
The coated wire setup is what I would call specialized but all of the parts probably cost less than 200$ if you are thrifty and are available between ebay, mcmaster, and home depot. The setup i have for glass melting uses a platum resistivly heated crucible that necks down to 3-5mm in diameter this can run up to 1100C this is expensive but unnecessary for polymer work. for polymer we can just usby jabberwocky - Plastic Extruder Working Group
Thanks for the link to the spoolhead extruder I had not seen that before I have only been working looking through the site for about a week. To answer your questions how do you push filament at 1/30 rate (for .5mm extrusion), yet push embedded wire out 30x faster? You cannot it is rather imposible to push the filament faster than the extrusion hence my comment about needing either a smallerby jabberwocky - Plastic Extruder Working Group
Hello, due to much dreaming about my reprap that is currently parts scattered though the mailing system and at home depot. I have been thinkering about other extrusion heads specifically heads that could be used to make electrical connections. My current thought pattern had resulted in manufacuting a new 3mm filliment that would consist of a metal probably copper thin wire centered in the 3mm fiby jabberwocky - Plastic Extruder Working Group
