Sorry it has been awhile since i last posted, but i have been busy getting ready for my next Comic-Con by building my Full Size Optimus Prime Costume.
I've decided to build the largest Delta Printer.
It stands 4'6" tall and 34" wide
And will have a print area of 450x450x450 give or take 50 mm height.
It is made out of 3/4" STEEL Square Tubing and all print jobs are 100% infil @ .1 or .2 layer, Depending on the location.
You will need 40' or square tubing at $26 at local scrap yard
You will need #8 self-drilling screws at 1'1/4, 3/4 and 1/2 inch. $6 a piece
You will need 2 8'x1/8x1 inch aluminum strips for counter swap support. @ $10 a piece
I am using 4 220x220 heat beds with their own 33amp power supply and 1 Power supply for the Board and Hotend. @ $14 on ebay https://www.ebay.com/itm/12V-220X220mm-Aluminum-Board-Hot-Plate-Heatbed-Heat-Bed-For-3D-Printer-Reprap-ES/332509925559?_trkparms=ao%3D1%26asc%3D51979%26meid%3Df390b373cefd4d23b696c7d255682d75%26pid%3D100705%26rk%3D1%26rkt%3D1%26%26itm%3D332509925559&_trksid=p2045573.c100705.m4780 I used Fireplace Mortar to glue the hot beds to a sheet of 20”x20” 3/16 aluminum sheet.
You will need 5 standard 12 vdc relays: https://www.ebay.com/itm/6Pack-12V-30A-Fuse-Relay-Switch-Harness-Set-SPST-4Pin-14-AWG-Hot-Wires/253167690800?epid=0&hash=item3af1f86430:g:OMIAAOSwXedZw09k Each Relay will have its own fan to keep it cool, Depending on which relay you get your wiring will be different.
The Magnetic Effector and Magnetic Carriages are from: https://www.thingiverse.com/thing:1584513/#files
I’ve modified the Carrier Carriage rail to wrap around the ¾ in tubbing and not sway. You can use the exciting wheels from your Kossel 800 Delta.
This is a build in progress so expect items to be added or removed.
I done this build to print the large items that my CoreXY printers couldn't print, plus i've read that magnet mounts make the walls and all around surface area smoother. Also i put my CoreXY printers to the test with my 405x305 delta, Same print jobs same specs, same infil and so on and the Delta printed the part in less time and smoother then the CoreXY. So I WIll be removeing all my CoreXY Printers and will be replacing them with Over Sized Deltas with Magnetic mount.
Project Update 5-8-2018: I've added some more Pictures.
Project Update 5-21-2018:I've added more pictures of the End Stops and Hotbed Mounts, along with some new Ramps 1.4 board/LCD.
this LCD/Ramps holder came from : https://www.thingiverse.com/thing:1639786
Project Update 5-23-2018: I've added some pictures and new STL's of Fan mounts for each of the ABC/XYZ Towers. If you plan in using 1/4 plywood as the base as i did then the Nema 17 Fan covers will not work. These new Alt Bottoms with fan support can mount 40mm fans and keep motor cool during those long print jobs.
