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).
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
Timing Belt
Joints
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.
Downloads
After finishing the first beta phase the construction drawings and LASER cut files will go online. Please wait...
