📋 Before You Print — Member Checklist

A few quick steps every time you start a print — please don't skip these:

1. 🏷️ Label your print with a sticky note. Write your name (and a phone number and/or email if you can) on a sticky note and attach it to the printer you're using. If a print fails or there's an issue, we need to know whose job it is and how to reach you.
2. ⚖️ Write down the filament weight. Note the weight the slicer estimated (in grams) on your sticky note. This is how we track material use for paying for filament — jot it down before you walk away.
3. 👀 Don't hit print and leave. Stay for the first few layers and make sure they're going down cleanly with good bed adhesion. The first layer is where most prints fail — catching a bad start here saves your whole print (and everyone's filament and time).

Safety & Usage Information

General Safety Rules

• Complete training before using any printer
• Sign in/out on equipment log
• Never leave prints unattended for extended periods (especially first layer)
• Report jams, failures, and maintenance issues
• Clean up after your print job

FDM Printer Safety

• Hot surfaces - Nozzle reaches 250°C+, bed reaches 100°C+
• Do not touch nozzle or heated bed during or immediately after printing
• Allow parts to cool before removing from bed
• Use scraper carefully to avoid injury
• Keep flammable materials away from printer
• Ensure adequate ventilation, especially for ABS/ASA

Resin Printer Safety

• Nitrile gloves are MANDATORY when handling resin
• Safety glasses required when working with resin
• Uncured resin is toxic and a skin sensitizer
• Work in well-ventilated area or use enclosure with extraction
• Do not pour resin down drain - cure and dispose properly
• UV light can damage eyes - never look directly at UV source
• Wash skin contact immediately with soap and water
• Keep resin away from heat and direct sunlight

Fume Safety

Material	Fume Risk	Ventilation Required
PLA	Low	Recommended
PETG	Low-Medium	Recommended
ABS	High - Styrene fumes	Required - Enclosed + Filtered
ASA	High - Styrene fumes	Required - Enclosed + Filtered
Nylon	Medium - May emit irritants	Required
Resin (all types)	High - VOCs	Required - Enclosed + Filtered

Post-Processing Safety

• Wear safety glasses when removing supports
• Use dust mask when sanding
• Heat guns can cause burns - use carefully
• Sharp tools (scrapers, knives) - cut away from body
• Spray painting - use spray booth or outdoors, wear respirator

Material Storage

• Keep filament dry - use sealed containers with desiccant
• Store resin in cool, dark place
• Resin has shelf life - check expiration
• Label all materials clearly

Approved Materials

FDM Filaments

Material	Enclosure Required	Notes
PLA	No	Beginner-friendly, low odor
PETG	No	Good strength, easy to print
TPU/TPE	No	Flexible, requires slower speeds
ABS	Yes	Requires enclosure and ventilation
ASA	Yes	UV resistant, requires enclosure
Nylon	Yes	Moisture-sensitive, needs drying
PC (Polycarbonate)	Yes	High temp, requires approval
Carbon Fiber filled	No	Abrasive - use hardened nozzle only

Resins

Resin Type	Notes
Standard UV Resin	General purpose, good detail
Water Washable Resin	Easier cleanup, still requires gloves
ABS-Like Resin	More durable, higher shrinkage
Flexible Resin	Shore hardness varies
Castable Resin	For lost wax casting - requires approval

Waste Disposal

• Failed PLA prints - can go in trash
• Failed ABS/other prints - check local recycling
• Uncured resin - cure with UV before disposal
• Resin-contaminated IPA - evaporate and cure residue, dispose properly
• Never pour resin or contaminated liquids down drain

Emergency Procedures

• Fire extinguisher location: [TO BE FILLED IN]
• First aid kit location: [TO BE FILLED IN]
• Emergency contact: [TO BE FILLED IN]
• Eye wash station location: [TO BE FILLED IN] (required for resin area)
• Skin contact with resin: Wash immediately with soap and water
