Quotes

A quote prices one ready file in one material at one quantity, without creating an order. Use it to show a price in your own shop, to compare materials or to check a design before you commit.

How a price is made

The file is sliced for real on our quoting profile for the material, with our house settings; a 3MF keeps the settings it was saved with. From the slice we take the weight and the print time, and the per-part price follows — the same price the calculator shows. Quantities are priced on full plates, then one partial plate; the unit price is rounded to the cent before it is multiplied.

Quantity tiers and your discount

The published quantity tiers apply automatically — 100+ of the same file carries 10 percent off the unit price, 250+ carries 20 percent. Your plan's discount_pct applies on top of the list price; a contract can set a different one. tiers on a priced quote lists the unit price at other quantities so your shop can show the ladder.

Pricing takes seconds to a few minutes. Poll GET /v1/quotes/{id} until status is priced or failed, or listen for quote.priced and quote.failed on your webhook.

GET /v1/quotes/{id} — priced

What the quote carries

Field	Meaning
`list_unit_price`	The per-part price at this quantity before your plan's discount, EUR, two decimals, as a string.
`discount_pct`	Your plan's discount, as a string.
`unit_price`	`list_unit_price` less the discount, rounded to the cent.
`total`	`unit_price` × `quantity`.
`tiers`	Unit price at other quantities — the ladder your shop can show.
`estimate`	What the slicer measured and used: `weight_grams`, `time_seconds`, `unit_yield` (parts per plate in a 3MF), `printer_model`, `nozzle`, `material`, `infill_pct`, `wall_loops`, `support`, `warnings`.
`estimate.warnings`	What the design-for-manufacturing pass flagged — thin walls, steep overhangs, a part laid out close to the bed's edge. Worth showing to whoever drew the part.

When pricing fails

status becomes failed, quote.failed is emitted, and failure_code with failure_message say what to do:

Code	What happened	Next step
`model_too_large`	The part is laid out larger than our print bed.	Split it into sub-assemblies, or send it through contact us and we take it by hand.
`not_a_model`	The file holds no printable geometry.	Export the part again from your CAD or slicer.
`material_unavailable`	The material is outside your plan or out of stock for this run.	Pick one from `GET /v1/materials`.
`slicer_rejected`	The slicer refused the geometry.	Check for open meshes, inverted normals and zero-thickness walls, or send it to us.
`file_unavailable`	The file was deleted or purged before pricing ran.	Upload it again.

Quotes and orders

A quote is information, never a commitment. The price on an order is computed again when the order is created and frozen when an engineer accepts it; the same file, material and quantity on the same day give the same number. Your plan's quote_daily_cap, when set, bounds the quotes you may create in a day; GET /v1/account shows usage.quotes_today.

Materials

GET /v1/materials lists what you can order: each material with its nozzles and colours (id, name, hex, in_stock), filtered by your plan's allowed_materials and allowed_nozzles. in_stock is live and never a promise. A colour left out of an item lets the engineer pick at production.
