Build it from shapes
Ten parametric primitives, snap-to-grid moves, mirror and align, group and ungroup. Flip any shape to a hole and it cuts through whatever it's grouped with.
Design it in your browser,
we print and ship it
Build a part from shapes, upload an STL, or just describe it and let the AI draft it — all in one 3D editor. Pick the filament, see the price live, and order.

The Designer
A real 3D editor and an AI that works on the same canvas
Drag in boxes, cylinders and holes, or upload your own STL. Then ask the AI for changes in plain English — it edits the exact model you're looking at. Every change is priced as you go, and what you see is what we print.
Or just describe it
"Add a 30 mm fan hole centred on the lid." The AI reads your canvas, makes the change, and hands the pieces back to you — still editable, still yours.
Priced while you work
Exact millimetre sizes, a filament picker from what's actually on our shelves, and a running price in the corner. One click to print options, no re-uploading.
- Free to use. Building, editing and saving cost nothing; only AI messages use credits.
- Bring your own STL. Upload it, drill it, split it, combine it with new shapes.
- Keep the file. Download the STL of anything you make for a credit — or let us print it.
What we do
Custom 3D printing without the runaround
cheap3dprinting.com is an on-demand 3D printing service for makers, hobbyists, designers, and anyone who needs a custom part. Design it in the browser, upload an STL or OBJ, or have the AI draft one with you, and we'll print it in-house on calibrated FDM printers. No quote requests, no minimums, no waiting for a sales rep.
How it works
From file to front door in three steps
Designed to feel like ordering anything else online — not like getting a quote from a vendor.
1
Upload or generate
Drop in an .stl or .obj file (with .mtl for multi-color), or describe the part to our AI designer and it'll draft one for you.
2
Pick a filament
Choose from the colors and materials we have on the shelf right now. Live inventory means no surprise stockouts mid-job.
3
Print & ship
Pay with Stripe. We print on calibrated FDM printers in our studio and ship via USPS anywhere in the US.
Materials
Filament for whatever you're building
PLA for beautiful, easy prints. PETG for tougher functional parts that can take a little heat and moisture. Other filaments as inventory rotates — you'll see the actual in-stock colors for your chosen material the moment you start an order.
Pricing
Pay for filament and machine time. That's it.
Every part is priced as filament grams used × price per gram plus machine time × hourly rate. No setup fees, no minimums, no quote requests. Supports are optional (about 40% surcharge if you opt in). Shipping is the live USPS rate — no markup.
