HS3 Safety Guide

This section should be thoroughly read and understood by all operators prior to using the HS3.

Safety Verbose

Throughout all Pantheon documentation , important safety considerations are set off from the main text with an associated signal word: DANGER, Caution, NOTICE. The signal word indicates the severity of the condition or situation. Be sure to read these statements and understand the severity of each. Be sure to follow the instructions for these statements. Below is a table describing each signal word.

Signal Word


Signal Word



Danger means that there is a condition or situation that will cause severe injury or death if the recommended actions are not followed.


Caution means that injury or machine damage can occur if the recommended actions are not followed.


Notice means that the text gives additional information or clarification.

General Safety Notes

Read all safety warnings, instructions, illustrations, and specifications provided in this manual and on HS3. Failure to adhere to all instructions may result in personal injury or damage to the machine. Only authorized or trained personnel may operate this machine. Untrained personnel presents a hazard to themselves and the machine. Always follow the guidelines from the relevant workplace safety authority in your area (OSHA, CCOHS, EU-OSHA).

HS3 Safety Precautions

  • Do not modify any files in the System Directory of the Web Console without specific approval from Pantheon.

  • Do not modify or alter any mechanical components of HS3 without specific approval from Pantheon.

  • Never reach into, or place any body part within the enclosure while HS3 is performing a print job.

  • If multiple people have simultaneous control of HS3, or multiple HS3 units, ensure a suitable workflow is in place to minimize the risk of the machine becoming active while an individual is in hazardous proximity to the machine.

Work Area Safety

  • The work area must be adequately illuminated and free from clutter.

  • Do not place HS3 in a confined space where heater elements of the system may significantly increase the temperature of the space.

  • Do not place HS3 in a position where it may accidentally be exposed to water or other fluids.

  • Do not place HS3 on an uneven or non-level surface. A flat and sturdy work surface is suggested.

Electrical Safety

  • Keep metallic objects or tools away from electrical connectors and terminations or while the machine is operating otherwise a risk of electrical shock exists.

  • When performing any maintenance tasks involving the electrical system, ensure the machine is powered off unless explicitly stated otherwise.

Personal Safety

  • Always use personal protective equipment when required.

  • Some components of HS3 can reach temperatures that can cause severe burns if handled without care. Thoroughly follow the instructions when dealing with such components.

  • Understand that HS3 is computer controlled and may move at unexpected speeds and distances. To prevent crush or entanglement risk, only open the enclosure of the machine when it is in a known and safe state.

Safety Topics Specific to Additive Manufacturing Systems

  • All fused deposition additive machines contain hazards from heat sources and automatically moving components.

  • All fused deposition additive machine create volatiles as plastic media is heated past it’s glass transition temperature. Be sure to use HS3 in a well ventilated area.
