Suggested Filaments and Settings
The below guide is highly dependent on your own printer, filament and printer profiles and experience. These settings are based on Hobbyking PLA
This guide has been recently updated based on feedback and experience from other builds. PLA has proven itself to be the best material for our use case (PETG was previously recommended however had significant cracking issues across multiple builds and as such is no longer suggested)
Good layer adhesion and high strength are the primary factors in determining your settings. There is no significant bridging or supports required on any parts and as such much hotter temperatures may be used that traditionally seen.
| Parts | Filament | Temp | Infill | Walls | QTY | Notes | |
| Assembly Tools | PLA | 235 | 20 | 3 | 1 x Each | PLA preferred as it is less likely to crack when tapping centre points | |
| Ball Screw Face Plates | PLA | 235 | 60 | 3 | 3 x Front 3 x Rear | ||
| BF/BK12 Mounts | PLA | 235 | 60 | 4 | 3 x BK12 3 x BF12 | ||
| Nema 23 Mount | PLA | 235 | 40 | 3 | 3 | ||
| Z Motor Mount | PLA | 235 | 60 | 3 | 1 | ||
| T8 Riser | PLA | 235 | 60 | 3 | 1 |
Ender 3 Print Profile
This is the Ender3 Profile that I use. It has been highly tuned and provides excellent quality results with very little stringing and high strength for all functional parts. To switch between PLA and PETG simply change the temps PLA: 235 (bed 40) PETG: 255 (bed 90)
0.6 Nozzle, 0.35 layer Height, 60mm/s This is a fast printing profile. The largest part (Dual Motor Mount) prints in ~5.5 hours
Have a profile for your model printer that you think will fit the needs of the PrintNC? Let me know and I’ll post it here too
