Description
Wood-D - Just another wooden 3D-Delta-Printer (Open Source Project)
Wood-D is a 3D-Delta-Printer based on LASER-cutted plywood. The joints are made of bearing balls and neodyn ring magnets.
Design Objectives
Specifications
Principle | Delta / Rostock | |
Construction | LASER cutted 4mm plywood (5 pieces a 400 x 300 mm) | |
Printing area | square 190 x 190 mm or circle 220 mm diameter |
fits PCB Heatbed. Heatbed shifted 15 mm in +Y direction |
Printing height | 225 mm | (at a linear system length of 650 mm) about linear system length minus 425 mm |
Dimension base box | 337 x 296 x 60 mm | |
Dimension top box | 337 x 296 x 20 mm | |
Dimension printer | 337 x 296 x 650 mm | depends on linear system length |
Joints | Magnetic (neodym ring magnets with bearing balls) | |
Drive | Stepper motors with timing belt GT2 or T2.5 |
Features
Based on the LASER cutted constructive parts you get a very high precision (nearly) without measuring and adjusting.
The plywood parts/puzzle are hold together with key and slots and a little bit of glue. Through the box design with cross bracing the stiffness is very high. The box design guarantees also a high angle precision.
Linear system rods are pressed in and the linear bearing are hold by a 2-componentt glue (epoxy).
Magnetic joints simplified the construction by giving a very high precision, less friction and zero backlash.
All non plywood parts are standard industrial parts you can buy in online shops and eBay. (only drive shafts have to be sawed)
Necessary tools: LASER cutter (visit a FabLab/Hackerspace in your area), hand saw for metal, screw drivers, inbus keys, gripper, cutter, soldering iron
Parts
Base and Top Box
Linear System
Beta 1: Standard industrial linear system with a 8 mm drive shafts and linear bearings LM8UU
Beta 2: Standard industrial linear system with a 12 mm drive shafts and linear bearings LM12LUU
Timing Belt
Standard industrial timing belt type GT2 with a 20 tooth pulley OR type T2.5 with a 16 tooth pulley
Joints
Magnetic joints made by neodym ring magnets (10 x 6 x 3 mm) with bearing balls (12 mm).
Beta 1: The balls are glued to the lift and carriage. The magnets are part of the rods.
Beta 2: The magnets are pressed in and glued to the lift and carriage. The balls are part of the rods.

Extruder Nozzle
A standard J Head Nozzle is used. See also RepRap Interface Standard RIS 1 for nozzle holder.
Extruder Drive
The drive case is also LASER cutted and is related to the Wade's Geared Extruder.
The details will be published in a seperate article.
Heated Bed
The base box is designed to hold a standard square PCB Heatbed (active area 180x180mm). Alternatively a disk with a diameter up to 300mm can be used (active area diameter 210mm).
Electronics
Any electronics compliant with RepRap Interface Standard RIS 1.
Used in Beta 1: Arduino Mega 2560 with RAMPS 1.4 shield and Marlin firmware
The electronic is mounted on a 'drawer' to easily adapt to any other design.
