Safety
Safe operation of the M3 / M3 Max printer requires that you read and understand the warnings below. Safety combines common sense, staying alert, and knowing how the M3 / M3 Max works. Be aware of the safety instructions below during operation.
For complete safety measures and information, please consult the Product Manual.
⚠️ 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.
⚠️ 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.
⚠️ UV emitted from this product
⚠️ 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.
- Be aware, parts may fall from build platform during platform removal due to poor adhesion.
⚠️ Ventilation
- Do not cover chassis ventilation slots or block enclosure openings.
⚠️ Manual
- 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, frame of the cassette, and top of the window. Do not use acetone to clean the printer door, printer deck, body panels, silicone spatulas, or plastic tool handles as it will damage or degrade them.
Sufficient ventilation is required during operation of the printer. The complete site prep requirements can be found below:
The printer has an E-stop button to be used in case of an emergency. Pressing the E-stop button vents the pneumatic system and cuts power to the motors and heaters, immediately stopping all printer activity. Only the computer within the printer remains powered.
The printer door must be closed before the platform can move or the printing process can begin. Forcing open the printer door causes the platform to stop. The door must also be closed for the platform to travel to the home height and lock in place.
Printing cannot start or continue if the cassette and platform become unlocked.
The heating system can only run during printing, and printing will abort if the maximum allowable temperature is surpassed.
A resin reservoir is located under the front of the deck. It serves as an overflow for large resin spills onto the deck. The projection volume (deck opening below the cassette) is not connected to the spill reservoir, so any spill into the projection volume does not flow into the spill reservoir and must be addressed immediately. For detailed instructions on cleaning a deck spill, refer to the Maintenance page.
