Cancelling the Print Farm? (Part 2)

Summary — Cancelling the Print Farm? (Part 2)

Overview

The creator purchased a building to convert into a 3D print farm. Initial progress was promising but ran into several problems: plumbing failures, required stamped engineering drawings for mechanical work, and potential fire-code questions about using consumer 3D printers in a commercial space. While the city paused mechanical work for lack of stamped engineering drawings, cosmetic finishes continued (ceilings, walls, trim, and prepping for new flooring).

Key problems encountered

• Plumbing backup: a toilet continuously ran and overflowed, causing sewage to leak under a wall into the unit.
• Multiple external gutter leaks discovered.
• Mechanical work (e.g., raising sprinkler heads) halted because the city required permits and engineered drawings.
• Potential regulatory issue: the city referenced the 2021 International Fire Code, which states non-industrial 3D printers must be listed/labeled to UL standards. Many consumer printers (for example, some Bambu Lab models) lack a UL listing and instead have CE certification. The creator has not yet been told they cannot use these printers; the situation is still under investigation.

Major construction, finishes, and decisions

• Flooring
  • Options considered: polished concrete, epoxy, luxury vinyl plank (LVP).
  • LVP selected for comfort and appearance.
  • Floor prep required grinding off old carpet glue — a multi-day, very dirty job.
  • Sprinkler heads were supposed to be raised before flooring; the contractor relocated heads to provide more headroom.
• Finishes
  • Ceiling sprayed black (creator preferred).
  • Walls primed and painted alabaster white; doors and trim painted black.
  • Offices, storage, and studio painted (studio painted a darker “peppercorn” color).
• Warehouse/storage
  • Storage/warehouse prepared for pallet racks.
  • Lighting being upgraded to LEDs.
  • Plan for a roll-up door for warehouse access.

Permits, timeline, and cost

• A full set of stamped engineering drawings is required to proceed with mechanical modifications.
• The creator hired an architect; the drawings cost approximately $6,000 and will take about two weeks before permit filing.
• This requirement pauses some mechanical progress until drawings and permits are obtained.

Risk mitigation and practical steps implemented

• Continue cosmetic finishes (painting, prep) while waiting for permits to maintain momentum.
• Protect printers from AC condensate/drips:
  • Install moisture sensors in air-handler pans and under the drop ceiling to provide early leak alerts.
• Separate storage strategy:
  • Prepare conditioned storage for sensitive equipment and an unconditioned warehouse for bulky inventory to keep stock out of the print room.
• Electrical/lighting:
  • Move to LED lighting in the warehouse.
• Signage:
  • Change exterior signage to reflect the business (rather than an HVAC company).

Actionable guidance (extracted from the video)

When converting a space into a print farm:

1. Inspect for plumbing and gutter issues early — expect surprises.
2. Choose flooring for both comfort and function; LVP is recommended for non-industrial print farms.
3. Prep concrete floors thoroughly (grind off old adhesive) before installing finishes.
4. Raise sprinkler heads or relocate them before installing flooring — but confirm permit requirements first.
5. Secure stamped engineering drawings before making mechanical modifications; budget for professional fees.
6. If air handlers are located above sensitive equipment, add condensate pan sensors and secondary sensors beneath to detect leaks early.
7. While mechanical permits are pending, continue cosmetic work that doesn’t require permits to keep progress moving.
