Safety
Safe operation of the L1 printer requires that you read and understand the warnings below. Safety is a combination of common sense, staying alert, and knowing how the L1 works. Be aware of the safety instructions below during operation.
For complete safety measures and information, please consult the product manual.
The L1 printer can only be moved using a forklift.
- Arc flash and shock hazard. Follow ALL requirements in NFPA 70E for safe work practices and appropriate Personal Protective Equipment (PPE).
- Do not attempt to override safety features. Doing so makes the printer unsafe.
Hazardous voltage inside.
- Disconnect power before servicing.
- Service by trained personnel only.
- Consult manual.
Pinch hazard
- Internal moving parts can cause severe injury.
- Watch out for pinch points and bump hazards.
- Only install/uninstall the cassette onto the printer deck schunks using the cassette cart. Do not install/uninstall manually.
- Use the built-in handles to install and remove platform.
Burn hazard
- Hot surfaces inside. Allow to cool before servicing.
- Take care when interacting with the cassette and surrounding deck after printing since they may be warm to the touch.
Lifting hazard
- If printing large parts, the platform may be heavy or unwieldy.
- Use the cassette cart to transport the cassette. Consider using 2 people to move the cassette if manual lifting/moving is required.
Health hazard
- Wear appropriate personal protective equipment (see below) whenever operating the printer, handling uncured resin/parts or in the production environment.
- Avoid skin and eye contact.
- Change gloves frequently.
- Wash hands frequently.
- Clean up resin spills (including drips) immediately to avoid slippery floors and prevent spreading of resin contamination.
- Power off printer before disconnecting coolant hoses.
- Be aware, parts may fall from build platform during platform removal due to poor adhesion.
⚠️ Do not cover chassis ventilation slots or block enclosure openings.
- Slots, grills, vents and fans provide ventilation for the L1 printer. Do not block or impede airflow into or out of these openings.
- ⚠️ Lock cassette cart casters when not in use.
- ⚠️ Never squirt solvent directly on the underside of the cassette, as it will cause immediate, permanent cassette damage.
- ⚠️ Only use acetone to clean the platform, printer deck, and frame of the cassette, and top of the window. Do not use acetone to clean the printer door, body panels, silicone spatulas, or plastic tool handles as it will damage or degrade them.
Compliance Printers are CE marked. The high voltage electronics, DC power supply, and pneumatics are housed in a locked NEMA box on the printer’s back.
Emergency stop The red knob on the front display will immediately vent the pneumatic system and stop power to all actuating mechanisms in the case of an emergency. Only the computer within the printer will remain powered. For more information see Emergency Stop in Operations.
Safety interlocks The door must be closed to start a print, and cannot be opened during a print. The door must also be closed for the platform to travel to the home height and lock in place. The platform stops at an ergonomic height after each print for removal and unlocks when the door is opened at the end of a print job. Printing cannot start or continue if the cassette and platform become unlocked. The cart is required to install and remove the cassette. The heating system can only run during printing, and printing will abort if the maximum allowable temperature is surpassed. Additionally, hardware thermal cutoff switches will disconnect power to the heaters in the event of a heater malfunction.
Spill prevention A secondary containment system is located within the printer under the light engine and will hold the full volume of coolant system should a failure occur. Additionally, a leak detector is tied to the fluid system valve and will not allow printing to start or continue if a leak is detected. In the event that a leak is detected, the system’s fluid coolant inlet valve is closed and a message will appear on the display.
Site Prep Sufficient ventilation is required during operation of the printer. The complete site prep requirements can be found in the General Site Prep Guide.
