Kobra
Kobra is an Anycubic Kobra Go.
Bed slinger, bowden tubed (ie. non-direct drive) 3D printer. Main modification is the part cooling fan which has required modifying the toolhead slightly. It should not affect day to day usage and nozzle swapping.
Filament
Only use the provided filament. Note that the majority of the filament in the Hackspace is currently 2.85mm diameter and Kobra uses the more common standard of 1.75mm.
Kobra is best suited for the following materials:
- PLA
- PETG
- TPU
Always use the correct slicing profile for the filament material you are using. Different filaments have different melting and burning points, so getting the wrong material type can end up with a scorched mess, or a failure to extrude with a strained extruder motor. ABS is not recommended because it is not enclosed. If the printer is enclosed in the future, then ABS/ASA printing will be a lot easier, otherwise you will have bed adhesion issues.
please contact the maintainers if you wish to use a filament that is not available.
Glue stick should not be required with the texture PEI bed.
Bed Levelling
Note that Kobra is very picky about the bed levelling procedure. The build plate should be perfectly aligned front to back and side to side for the probe to properly detect the build plate. Otherwise the printhead will collide with the build plate.
The procedure to get proper bed levelling is to set the build plate properly and run the bed levelling procedure from the screen. Once it has saved the bed mesh, you can adjust the Z-offset which determines how high the printer will keep the nozzle above the print bed.
Cost
Using the printers costs £1.50/hour of printing + 50p/meter of filament. Octoprint gives you both of these.
Training
Training is required. There is a cost of £10 to be trained, payable to the trainer.
Logging
All prints are to be logged via Google form once it is updated.
Risk Assessment - 3D Printers
This risk assessment is intended to provide guidance on the risk associated with the above equipment and activities in normal use. Please also check general risk assessments for the space as a whole. Any discrepancies, errors or concerns should be raised with the document maintainers or trustees - do not edit this assessment directly. For responsible persons and last update, see 'version log' of the assessment page.
Activity

Signage
Understanding Risk Rating
LOW - Ensure current control measures are in place and continue with activity
MED - Control measures may be adequate, co-supervision is recommended
HIGH - Do not undertake activity without further consultation with area specialists
Risk Assessment
| Identify Hazards | Who May be Harmed and How | Severity | Control Measures | Likelihood | Risk Rating |
|---|---|---|---|---|---|
| Hot end and bed of 3D Printer | User – Minor Burns | LOW | Do not touch the printer components once printing has begun. First aid kit provided. | LOW | LOW |
| Portable Appliance | User – Electrical shock | HIGH | Regular visual inspection schedule. Regular Maintenance schedule. All printers remain permanently plugged into designated outlets. | LOW | MED |
| Portable Appliance | Premises – Fire Risk | HIGH | Regular visual inspection schedule. Regular Maintenance schedule. | LOW | MED |
| Fumes | User – Respiratory difficulties | MED | When using Acetone, IPA or other adhesion or welding chemicals, wear appropriate PPE. Keep area around printer clear when printing ABS. Keep area well ventilated when printing ABS | LOW | LOW |
