Who uses our 3D printing service

  • Inventors & makers — test-fit prototypes before committing to CNC or injection molding
  • Small businesses — jigs, fixtures, brackets, and low-volume end-use parts
  • Engineers — functional FDM parts in PETG, ABS, or PLA-CF for shop and field use
  • Hobbyists — custom enclosures, adapters, and replacement components
  • Production shops — fixtures, gauges, and shop aids for repeatable workholding

How the instant quote works

  1. Upload your STLs — one part or a full kit, millimeter units, up to 50 MB each. Preview each file in 3D.
  2. Configure each part — material, color, layer height, infill, and quantity can differ per file.
  3. Get a combined estimate — one setup fee, slicer-based print time, and a USPS Flat Rate box for the whole order.
  4. Submit for review — we confirm printability and final pricing within one business day.
  5. Pay with Stripe, then we ship — same secure card checkout as the shop, then USPS Priority Mail Flat Rate.

Why order 3D prints from Helios Systems

  • Real shop, real engineers — not a faceless upload-and-forget broker
