Hull
Hull is a Lulzbot Mini Standard.
Accessible via http://hull from inside the hackspace network.
Filament
Only use the provided filament.
Hull will theoretically print the follow filaments:
- PLA
- ABS
- XT
- Nylon
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. Beware that ABS is alphabetically first on the drop-down but less likely to be used.
please contact the maintainers if you wish to use a filament that is not available.
There is no need to use Pritt Stick, or other adhesive, to get the print to adhere to the bed with rigid filament. Applying excessive Pritt Stick merely cakes the bed in gunk, making the first few layers of your print look messy and lumpy. If you find the bed like this, it can be cleaned off with a warm soapy sponge.
When changing filaments between different plastic types with different melting points, manually select the tool temperature to be the hotter of the two when flushing out the remains, or you will find that the lower temperature filament can't push through the remains of the filament that may be left in the hotend or nozzle.
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 (waived if trained on the old printer), payable to the trainer.
Logging
All prints are to be logged via : http://goo.gl/forms/ARNWXexh7zXHSq8p1
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
3D printing in plastic material
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 |
