15-year-old Maker creates a DIY 3D printer for $400

Several months back, 15-year-old Braden designed a DIY 3D printer with an approximate $400 build of materials (BOM). The Delta Twister build — which was recently posted to Instructables — had also been an entry in the site’s Arduino contest earlier in the year.

“Anyone can build the Delta Twister! You don’t need any 3D printed parts or CNC to make this printer. Everything except the extruder can be made using hand tools like I did,” Braden explained in the Instructables post.

“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 $800-3,000.”

Aside from its Arduino Mega 2560 (ATmega2560), other notable Delta Twister specs included:


(1) Ramps v1.4 board with drivers
(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 length of belt that fits your pulley
(1) RepRap heated bed
(3) 3d printer endstops
(1) PC power supply
(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

Braden kicked off his DIY 3D printer project by building a frame. He then fashioned linear rod supports, cut the rods and dowels to size, made an arm carriage, screwed in the rod supports, put together the motor mounts and printer head carriage, and attached the endstops as well as the belt pulley system. 

On the software side, Braden used Repetier Host for the 3D printer, along with Marlin firmware for the Arduino board.

“[Yes], it will take a little bit of tinkering around to get prints looking like you want them to, but hey, you now have a working 3d printer,” Braden added.

Build your own ceramic 3D printer for under $700

A Maker by the name of Johnathan Keep has unveiled a new Ceramic Delta 3D Printer powered by an Arduino Mega 2560 (ATmega2560). The build, which only cost about $700, is capable of printing a clay medium opposed to the more traditional plastic filament.


According to Keep, “The aim of the design was to keep it simple, using basic DIY skills and parts available on the Internet.” And, while the design is specifically created to print clay, it could be adapted to work with other materials, the Maker adds.

Based on ‘delta’ style 3D printers, the DIY design is comprised of modified parts from a Techcon Systems dispensing gun for the extruder — including the gun’s cartridges and retainer body. Compressed air is used to extrude the material from the cartridge and is capable of providing around one hour’s worth of printing before it needs to be replaced.

The Maker elected to equip the printer with an Arduino Mega 2560 (ATmega2560) in order to drive the three high torque stepper motors to position the guide rods. The rods are held in place using MDF and plastic pieces as a platform and open-frame top to allow for movement while being stable. The project also is controlled by a RAMPS 1.4 set.


“Annoyed and frustrated by 3D Systems buying out and then stopping the production of the RapMan 3D printer. This was the first kit printer Belgian design duo Unfold adapted to print with clay and has subsequently been copied and widely used by others, I decided to develop my own replacement 3D printer,” the Maker elaborates on his blog. “By 3D printer standards this is a rather primitive tool set, but it does offer an accessible way into a very exciting new way of working with clay.”
