Resin is estimated at 0.05 mm layers. Filament layer height and infill settings do not apply.

How this estimate is calculated
Filament: £5 minimum order · £2 setup per order · £0.50 per estimated hour. Material: PLA £12/kg, PETG £15/kg, ABS £16.50/kg.
Resin: £10 minimum · £10 setup per order · £0.45 per estimated hour, with no separate material charge. Assumes 0.05 mm layers, eight seconds per layer and 15 minutes allowance per part.
Supports, orientation and batching need review. Delivery and any applicable tax are quoted separately. An enquiry does not place an order.
Final specification, price and delivery confirmed by email before you order.
From a model file to a print estimate
- Choose your STL or OBJ. Export it in millimetres. The preview shows the model's dimensions and solid volume so you can check that the scale looks right. If you are just researching, try the sample model.
- Set the specification. Compare PLA, PETG, ABS or resin. For filament prints, change layer height and infill to explore how the estimate changes. Set a quantity from 1 to 100 copies of the same model.
- Prepare a reviewed quote. Choose “Request this print” to open your email app, or copy or download the enquiry text. Attach your model before sending it to [email protected].
The tool is free to use. Printing is a paid service, and an estimate or enquiry does not place an order.
What is included in the calculation?
Filament estimates use a £5 minimum order, a £2 setup fee per order, material and estimated printing time. Resin uses a £10 setup fee per order plus estimated printing time, with a £10 minimum. Open “How this estimate is calculated” above or read the pricing rates and worked examples for the calculation.
The result is an initial print estimate. We review orientation, supports, finish and any important fit requirements before confirming the final specification and price. Delivery and any applicable tax are quoted separately.
Which files can I use?
The calculator accepts closed STL and OBJ meshes up to 25 MB and 400,000 triangles, with no dimension above 300 mm. Export in millimetres: the tool uses the model's coordinates and does not infer the intended unit.
STEP and 3MF files, larger models and more complex projects need a manual quote. These are calculator limits, rather than a statement of what every project can be printed. Use the file preparation checklist before exporting.
What the file checks can tell you
The tool checks for measurable solid geometry, invalid coordinates and open or non-manifold edges. A rejected mesh may need repair in your design software before it can produce a useful volume estimate.
Passing these checks does not confirm that a part can be manufactured as drawn. Thin walls, small gaps, supports, orientation and material suitability still need review. The calculator is an estimate tool, not a slicer or mesh repair service.
Comparing a single print with a batch
The quantity control estimates 1–100 copies of the selected file at the published standard rates. For different designs, send each file with its own quantity. Read about small batch printing, or request a tailored bulk quote for 100+ units. Bulk discounts are not applied automatically by the calculator.
Do I need to upload my design to get an estimate?
No. Choosing a file lets the calculator read it locally in your browser; it does not send the model to 3DToDoor. To request a reviewed quote, attach the file to your email and include its intended use, preferred colour, delivery postcode and required date.
