3D Printer DIY: The 2025 Service-Provider Build & Scale Handbook
Why 3D Printer DIY Beats Outsourcing in 2025
3D printer DIY empowers service providers to cut per-part cost by 28–41 %, shrink lead-times to <24 h, and retain full IP custody. With global demand projected at USD 51 B by 2027, owning your own fleet is no longer optional for serious bureaus.
