Build


Basics

  • A variation of the D3D 3D Plastic FDM Printer that has a 12 inch print bed, Made with a PVC frame

http://opensourceecology.org/wiki/D3D_Extruder

CAD

Most recent Render: http://opensourceecology.org/wiki/File:D3D_OHIO_18.01_V0.3_WIP.fcstd

BOM

  • Sensor - 8 mm sensing - 18 mm diameter - [1]

Users Prusa I3 Extuder module Prusa I3 MK2 here. the replication of this module used in the D3D ohio v18.02 is here: https://wiki.opensourceecology.org/wiki/D3D_Extruder_v1807 https://wiki.opensourceecology.org/wiki/D3D_Extruder

Modeling

The intention of this section is to show the most up-to-date CAD module visually as it is developed. Versus the development log, this will attempt to show the "best" work or "Stable" versions

V1.0.0 Latest version uploaded.

-Uses short idler. 500mm steel rods. allows for an extra inch on x and y axis.

Ready for calculation review!

V0.3 DONE - This will be a rendering with 1" PVC tube and corners, 12" bed and a http://opensourceecology.org/wiki/File:Prusa_i3_mk2_extruder_adapted.fcstd extruder changed for what is currently present in V0.2

This file has been uploaded as is, currently we just have some part movement and a 12" bed

Development Log

8/4/2018

-worked on drilling and mountings for D3D PVC. testing cuts and cutting methods with .5" scrap them moving to 1" pipes. https://photos.app.goo.gl/Km166hmZpXR9EKHQ9

-updated calcs with screw sizes found and other details. https://photos.app.goo.gl/PjMYwAJp2ibobuVW6

7/17/2018 to 7/29/2018

  • All parts for D3D extruder have been ordered and arrived.
  • Recieved a Prusa I3 that WORKS and can now PRINT.

https://photos.app.goo.gl/m48aZE4RAawdjJKU7

  • took printer to a company hackathon and demonstrated the Universal axis. Measured and ordered screws that will work for mounting the axis to .5" and 1" PVC pipes

6/01/2018 to 7/16/2018

Attempted to get mark 8 extruder functional this failed. during this time, ordered extuder parts from Steven (OSE).

The arrived parts did not fit my specific J-head hot end.

Was refered to this BOM https://docs.google.com/spreadsheets/d/1WNRJfb56ilHlIcdcz5cS92sy0QnUK5MiNVzNW1Jf7Lc/edit#gid=0

and this part https://www.ebay.com/itm/DUAL-E3D-V6-J-head-Direct-Hotend-Kit-1-75-12V-All-Metal-Throats-Hot-End-USA-/292208050774?hash=item4408f50256:g:MkEAAOSwKJRZicAS which provided a secure fit once purchased.

Currently waiting on family fianicial situation to improve with a recent layoff, then Will grab the rest of the componets needed (MISC screws and other parts) may also get a ali-express order of the parts as they are affordable, but take longer to get here.

5/27/2018 to 6/01/2018

Hiatus due to day job - commission a sewer lift station


5/27/2018

Summary:

  • Finish belt routing
  • more electronics work
  • Axis mounting on frame
  • Research on how rods are used to hold up the z axis?

5/20/2018

Summary: Routed the tension belts for uAxis's... started setting up electronics

Some issues and questions:

  • How do I do the heated bed? Sil. Pad under alum, then plastic printing sheet attached to alum?
  • Found some instruction here: http://opensourceecology.org/wiki/D3D_PVC_pipe_8in_bed and here:
  • Issues today getting a print from old printer with newest ordered J-Head and Mark-8 extruder from Geeetech... jammed and removing jam with acetone.

-Where can I just buy a working extruder for now? I need to print or grab a printed version of our adopted extruder.

Ideas and innovations Had and idea for a magnetic adaptor for frame mounting Could I make a device that is PVC printed that allows the D3D frame to grab on to a PVC fitting with magnets?

  • Would be Two clamshells, perhaps the interior features would be jagged, or sprayed with spray rubber.
    • Perm. magnets at either end for grip.
    • One of the clam-shells would have a place for a screw to pass compleatly though
    • would make the frame a small bit bigger. would be nice to have this Grab onto the PVC versus drilling though it

5/8/2018

To get this up to date, the CAD is rendered.

Today, I am assymbuling the printer. I have 4 of the Universal Axis Units built, but only have the timing belt in one of them.

GOAL: From today, I am going to try and cut the PVC pipes.

11:30 From the D3D frame gen, I have a pipe length of precisely 493.546mm that's 19.43094488"... so, I'll rationalize this down to 19 1/25" because then, you can push the pipe in so it totally snugly grabs around the corner fitting. I'll see how this cut works.

all cuts took a half hour. I like this fit. ! Pictures as soon as I get my file server up again... Update 5/20 picture of build at this time:

PVC frame and X and Y assym

3/2/2018

Found a Basis for a render http://opensourceecology.org/wiki/File:Medium_Size_Version_12_in.FCStd

So ploted up: First Rendering!

I have a great deal to learn in Freecad on more adv. assym work. Such as how There are parameters for assymblies, and there is a linked parameter for rod lenght between the Right and left Y universal axis so you can change lenght in one spot. super cool.
