Read the first 7 3D Printing & Maker Spaces flashcards as text

  1. An ISO 14001 auditor is reviewing water use in a maker space with post-processing operations. Which activity is most likely to generate contaminated wastewater requiring controls?

    Answer: Washing resin prints with isopropyl alcohol (IPA)

    IPA wash baths for resin prints accumulate dissolved photopolymer resin, creating hazardous solvent waste that cannot be poured down a drain.

  2. A maker space EMS has set an objective to reduce failed print waste by 20% in one year. Which leading indicator best measures progress toward this objective?

    Answer: First-layer success rate tracked per printer per week

    First-layer success rate is a leading indicator that predicts future waste generation, allowing corrective action before waste accumulates.

  3. When an EMS internal audit scope includes a maker space, which of the following external interested parties is most likely to have legally binding environmental obligations on the organization?

    Answer: Local fire marshal and hazardous materials regulator

    Fire marshals and hazmat regulators impose legally binding requirements for storage, handling, and disposal of flammable solvents and hazardous resins.

  4. A maker space stores five gallons of IPA solvent for resin cleaning. Under an EMS, this storage situation requires evaluation against:

    Answer: Local fire codes, EPA solvent regulations, and the EMS spill emergency response procedure

    Flammable solvent storage triggers fire code compliance, EPA waste regulations, and must be covered by the EMS emergency preparedness procedure.

  5. Which document would an EMS auditor request to verify that maker space staff are competent to handle photopolymer resins safely?

    Answer: Training records and Safety Data Sheet (SDS) review acknowledgments

    ISO 14001 Clause 7.2 requires documented evidence of competence for personnel performing tasks with significant environmental aspects, including SDS comprehension.

  6. A maker space recently installed a carbon filtration unit on its enclosed resin printer. From an EMS audit perspective, this change should be captured in:

    Answer: The environmental aspect register and operational control procedures

    Adding a control measure for a significant aspect (VOC/particle emissions) requires updating both the aspect register and the operational control procedure that governs printer operation.

  7. An auditor finds that a maker space disposes of empty resin cartridges in the general recycling bin. The correct EMS-based response is to:

    Answer: Record a nonconformity because residual resin makes cartridges hazardous waste requiring segregated disposal

    Containers with residual uncured resin retain their hazardous classification and must be disposed of as hazardous waste, not commingled recycling.
