Description
Wood-D - Just another wooden 3D-Delta-Printer (Open Source Project)
Wood-D Extruder Drive is a simple filament bowden extruder based on LASER-cutted plywood.
Design Objectives
Specifications
| Principle | Bowden Extruder like Wade's Geared Extruder | |
| Construction | LASER cutted 4mm plywood (1 piece a 102 x 295 mm) | |
| Filament | 1,75 mm | |
| Dimension case | 100 x 60 x 32(+Gears) mm | |
| Drive | NEMA 17 Stepper motors |
Features
Based on the LASER cutted constructive parts you get a very high precision.
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.
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, gripper, cutter, soldering iron
Parts
Case
LASER cutted plywood or MDF
Drive
Hobbed Bold M8 x 60 (as in Wade's Geared Extruder)
Gears
Standard industial gears 72+24 module 0.8 OR gears from Wade's Geared Extruder
Motor
NEAM 17 stepper motor as usual in RepRap projects
