How do you start a 3D printing service business in 2027?

Honest 5/10 take.

Startup costs: $3K-15K. Entry FDM printers (Bambu Lab P1S, Prusa MK4) $700-1.5K each; resin (Elegoo Saturn) $400-800; filament/resin stock $500-1K; post-processing (cure stations, sanders, paint booth) $500-2K. LLC + insurance $300-800. Workspace ventilation matters for resin.

Tools/software: Bambu Studio, PrusaSlicer, Cura for slicing. Fusion 360 or OnShape for CAD ($0-545/yr). Order management via Shopify or custom forms. Treatstock/Craftcloud for marketplace listings. QuickBooks for taxes.

Customer acquisition: Etsy for figurines/home goods (saturated, race-to-bottom). Local Facebook groups for prototyping leads. Upwork/Fiverr for one-off jobs. IG/TikTok for niche prints (cosplay props, tabletop minis, replacement parts). Craftcloud aggregates B2B prototyping. Cold-pitch local engineering shops.

Revenue model: Per-print + material markup (3-5x filament cost). Custom design fees $50-200. Small-batch production runs $500-5K. Subscription minis $15-50/mo.

Year 1: $15K-60K gross typical for solo. Margins 30-50% after material/electricity/failed prints. Saturated hobbyist market; B2B prototyping and niche cosplay/tabletop pay better than generic Etsy stock.
