3D Printing & Maker Spaces Flashcards

When auditing a maker space under ISO 14001, which aspect of FDM 3D printing most commonly constitutes a significant environmental aspect?

Answer: Volatile organic compound (VOC) emissions from heated thermoplastics

FDM printing heats thermoplastics to high temperatures, releasing VOCs and ultrafine particles that are a primary air quality concern under ISO 14001.

A maker space uses a resin-based SLA printer. Under an EMS, spent resin and failed prints should be classified as:

Answer: Hazardous waste requiring special handling and disposal

Uncured photopolymer resin is classified as hazardous waste under RCRA regulations due to its toxic and reactive properties.

During an EMS internal audit of a maker space, an auditor finds no documented procedure for filament purchasing decisions. Which ISO 14001 clause is most directly affected?

Answer: Clause 8.1 – Operational planning and control

Clause 8.1 requires documented operational controls for activities associated with significant environmental aspects, including material procurement decisions.

A maker space is evaluating switching from ABS to PLA filament. From an EMS lifecycle perspective, the primary environmental advantage of PLA is:

Answer: Biobased origin and compostability under industrial conditions

PLA is derived from renewable plant starch and can be composted in industrial composting facilities, offering a lifecycle advantage over petroleum-based ABS.

An EMS auditor notes that a maker space printer enclosure has no ventilation system. The most appropriate audit finding category is:

Answer: Major nonconformity

The absence of ventilation for enclosed resin or ABS printers represents a systematic failure to control a significant environmental aspect (VOC/particle emissions), constituting a major nonconformity.

Which metric would be most meaningful for an EMS energy baseline for a maker space with 10 FDM printers?

Answer: kWh consumed per kilogram of material successfully printed

Normalizing energy use to output (kg printed) creates a meaningful baseline that accounts for production volume changes, enabling accurate performance tracking.

During an audit, a maker space demonstrates that it recycles support material waste by returning it to a filament recycling vendor. This practice best maps to which EMS concept?

Answer: Circular economy and waste hierarchy application

Returning waste filament to a recycler applies the circular economy principle and sits near the top of the waste hierarchy (recycle over dispose).
