The 3d printer that i am about to show you how to build is not only one of the most affordable printers, but also is on of the most simplistic. Anyone can build the Deltatwister! You don't need any 3d printed parts or cnc machine to make this printer...Everything except the extruder can be made using hand tools like I did. Being 15 years of age i designed and built this 3d printer. Practically anyone with basic mechanical skills can build their own Delta Twister! Having a print volume of over 1000 cubic inches this printer really has it all...for only $400 compared to $800-3000. If you like what you see then please vote for me! I would really appreciate it.
Step 1: Gathering Your Materials
You will need:
(1)Ramps v1.4 circuit board with drivers
(1)Arduino mega 2560 circuit board
(3) 36" 8mm linear rods
(6) 8mm linear bearings
(2) 3/8 in wooden dowel rods(4 feet each)
(12) 8mm rod ends
(4) nema 17 stepper motors
(3) stepper pulleys for a 5mm shaft
(1) 6M legnth of belt that fits your pulley
(1) rep rap heated bed.
(3) 3d printer endstops
(1) pc powersupply.
(3) computer fans
(1) j-head printhead
(1) extruder with a bowden tube(airtripper has a good unit).
(1)Meter of 1.75 mm Teflon tubing
This should total out to well under $400.
Step 2: Building Your Frame
The frame is key to a successful 3d printer.
What I did was make two equilateral triangles with sides two feet in length. I then cut 4.5 inch equilateral triangles off each of the vertices. I then made 3 pieces 4.5x38" as the sides. I included a picture of the triangle if that will help.
I then used 1" sections of 2x4's to act as supports for the main pieces. The long pieces are all 38 inches x 4.5 inches.
