3D Printer - Working Area 40x40x40cm
by Thomas Workshop Hello everyone, in this project I want to show you how to make a 3D Printer. I always wanted to have a diy 3d printer The esayies way to make it is print frame parts and coonnect it with aluminium profiles or somethink like that. But I didn't have acces to any 3d printer. So, I used my cnc machine to make all nessesery parts and when 3d printer was almost assembled I printed plastic parts whitch were hard or imposible to make on cnc machine. And now i have a 3d printer with working area around 40x40x40 cm :) I made a video and step by step instruction how to make it.
Step 1: Watch the Videos
I made three videos which show you step by step assembly of 3d printer. Videos will give you a good overview, but most important information are in the next steps. https://youtu.be/Qn1NkI5KSDk https://youtu.be/SYLHYfk-hU https://youtu.be/kDu_nKugWgY
Step 2: Materials, Parts, Tools
Frame materials:
- Aluminium profiles 20x20x2 mm
- Aluminium sheet 3mm
- Linear Rail Shafts 12mm
- Linear Shaft Bearings 12mm
- A lot of Screws, Nuts and Washers
- Stepper Motor Mounts Drive components:
- Stepper Motors Nema 17
- Timing Belts GT2 6mm
- GT2 Timing Pulleys
- Screw Rods Electronic:
- Arduino Mega 2560
- Ramps 1.
- Stepstick A
- LCD 12864
- Power Supply
- Heated Bed
- Heater Block
- Endstops
- Thermistors
- A lot of Wires Tools:
- Cnc Machine or 3D Printer
- Belt Sander
- Angle Grinder
- Drill
- Sandpaper
- Screws drivers
- Soldering Iron
- Pliers
Step 5: Frame + Y Axis
Connect aluminium profiles (585mm and 620mm length) with corner connectors using screws. Remember about the angle of 90 degrees! Cut the linear rail shafts to 620mm. Screw Y shafts holder to the frame. Put in linear bearings to the bearings holder and put them on shafts. Next screw the bed bottom to the bearings holder. This is a platform for the bed.
Step 7: X Axis
Screw bearings to the X Plates and put them in the Z axis. Remember about a bearing holder+nut one of each side. Cut the shafts to 624mm. Connect bearings with X Bearings Holder and screw them to the X Plate Extruder. Now frame and axis are ready :)
Step 10: Steel Platform
This step is not necessary but is good for your machine. The construction is little flexible when you put on force. To reduce it I welded simple platform with steel profiles.
Step 11: Electronics, Heated Bed, Power Supply
The brain of the printer is Arduino Mega 2560 with Marlin software. To arduino are connected Ramps 1. shield and LCD 12864 Smart Controller. To power the printer I used a ATX power supply (very cheap and quite). But if printer works with 4 heated beds my old atx isn't enough. To power the 4 heated bed I used a power supply from old server station. To control which bed will be turned off or on, I made small control panel (schematic below). If I need use more than 2 beds, I have to turn on biggest power supply(a lot of noise). Of course you can power everything from 1 power supply, but I got my power supplies for free and this solution is good for me becouse I mostly use 1 heated bed. On the bottom of the heated bed is a cork board to keep maximum heat.
Step 12: First Printing
Before machine was completely finished, I printed a hotend holder, fan holder, z axis threaded rod holder, smart controller enclosure and filament spool holder.

Step 13: Finish :)
3D Printer is completely finished :) Just heat the nozzle and print something! If you enjoy please subscribe my Youtube channel for more projects.
