3D Scanning and Printing¶
Group work with Theo Gautier from Agrilab¶
We tested the limits of the 3D printer machine : Original Prusa i3 MK3 by Josef Prusa
- First choose a “torture test model” for the 3D Print.
- We chose the “All-In-One” from All3DP
- Download Ultimaker Cura
- Open it and add your 3D printer :
- Open the test file by clicking on “crtl” + “o”
- Set your parameters regarding what you want. For the test, we kept the default parameters.
- Save your file as a “.gcode” on your computer by clicking on “Save to Disk”
- Save it to the 3D printer SD card
- Put it in the machine
- Select your file
- Check the parameters on the printer screen
- Launch it ! and you will see the machine begining heating
- The machine starts by making a trial to set its X,Y and Z coordinates. You can remove it.
- Then it starts with the first layer :
- Make sure you have enough time because printing lasts more than 6 hours for this model.
Final result :
We analysed different points :
- Angle limits : beyond 60° a support is required
- Edge distortion without a plate adhesion :
- Bridging limit : beyond 0.7mm a support is required
- The external diameter is as parametered but not the internal one because the nozzle is 0,4mm :
- You can add a support that you will remove if you want to make a large bridge :
- On the X and Y axis the machine works well :
- On the Z axis, some irregularities are realised because of the nozzle moves :
