Every day, one business taken apart with verifiable numbers, real margins and an explicit verdict.https://theroughmath.com/en-GBhttps://theroughmath.com/report/3d-printing-service-on-demand-margins/https://theroughmath.com/report/3d-printing-service-on-demand-margins/Consumer printing is a race to the bottom — 68% price collapse in two years, and an unaudited industry estimate puts break-even failure at ~65% of shops. Only direct B2B work at roughly €18-27 a job survives, and that is a sales business, not a printing one. A €18 marketplace sale leaves €6.75 once labour and failed prints are counted. That means ten sales a day for €2,000 a month — in a niche where prices fell 68% in two years.Fri, 21 Aug 2026 00:00:00 GMTManufacturing3d printingmanufacturingmarketplaceetsyb2bprototypinghttps://theroughmath.com/report/self-service-laundromat-cycles-per-day-break-even/https://theroughmath.com/report/self-service-laundromat-cycles-per-day-break-even/Most named operators closed, stalled at breakeven, or posted losses; both clear survivors were multi-site.
