For AI agents

If you are a person reading this: the page is written for AI assistants. Give yours this page's address together with your part, and it will work out what we need to know before you ask for a price: what the part does, how hot it gets, what load it carries, what it touches, how it has to look and when you need it. A request with those answers gets a price with fewer questions back, and lets us choose the material, the print temperature, which way up the part is printed and how fine the layers are for your actual use instead of a guess. You can also answer the same questions yourself on the quote form.

For the agent

What to find out, and why

You are helping someone get a part made by druckworks, a Latvian 3D-printing service. We print with FDM only: plastic filament, laid down layer by layer. A person here reads every request and replies by email with a price, in 3 hours on average. Sending a request orders nothing.

Collect the answers below, from the person and from what you already know about their project, and write them into one brief. The questions follow the quote form, so every answer has a place to go.

How to ask
  • Do not guess. "Not sure" is a useful answer. A confident wrong number sends us to the wrong material.
  • Find out what you can before you ask. If you have a drawing, the mating part's datasheet or the earlier conversation, read it first.
  • Ask in plain words. The person does not need to know what FDM, infill or layer adhesion mean.
  • Give numbers with units: mm, °C, kg, pieces, a date.
  • Show the person the finished brief before anything is sent.
  1. 01

    What is there to print from?

    Find out

    • A 3D file: STL, 3MF, OBJ or STEP, in millimetres. Up to 25 MB each, ten files at most.
    • No file: two photos from different angles on a plain background, a ruler or a coin beside the part for scale, and its rough size in mm.
    • Nothing yet: what the part is and what it fits onto, for example "a bracket to hold a sensor onto a 35 mm DIN rail".
    • GLB, GLTF, FBX, USDZ, BLEND, DAE and PLY cannot be printed from. Export STL or 3MF instead.
    • The overall size. Our largest single part is 340 × 320 × 340 mm. A bigger one can sometimes be split and joined, and a person checks whether that works.

    What we decide with it

    A file lets us measure the part's volume and size, which set the material and the machine time. Without one, we draw it: modelling is its own line on the quote, charged by the hour, and the person sees it before anything begins.

    Goes into: Quote form: "What have you got?" and the upload. API: files.

  2. 02

    What is it, how many, and what does it do?

    Find out

    • The part in plain words, for example "dishwasher basket clip, snapped at the hook".
    • How many.
    • What it does in use: what it holds, carries, covers or attaches to, and how.
    • Whether it has to flex, snap, hinge or seal, or stay rigid.
    • If it replaces a broken part: where and how the old one broke.
    • Whether it touches food or drink, and whether its failure could hurt someone.

    What we decide with it

    The use decides the rest. Where an old part broke shows us where the load runs. A part that flexes needs a different material from one that must stay rigid. We certify no part for food contact and we do not print safety-critical parts, so it is better to know that now than after the price.

    Goes into: Quote form: "The part" and "How many". API: part_description and quantity.

  3. 03

    How hot will it get?

    Find out

    • The hottest temperature it will ever see, in °C. The peak, not the average.
    • Where it lives: indoors, outdoors in sunlight, inside a car, near a motor or a heater, in a dishwasher.
    • If the person only knows the place, use the reference points below to turn it into a number, and say that you did.
    Up to 45 °C
    a shelf, a desk, a cupboard indoors
    Up to 60 °C
    a dishwasher's main wash
    Up to 70 °C
    inside a parked car in the sun · commercial electronics
    Up to 85 °C
    industrial electronics · a sanitising rinse
    Up to 100 °C
    boiling water · a dashboard in the sun
    Up to 105 °C
    cabin-mounted car electronics
    Up to 125 °C
    body electronics, radar, infotainment
    Up to 150 °C
    under-hood and on-engine modules
    Up to 175 °C
    near the hot parts of a turbo engine bay
    Up to 196 °C
    PPA-CF territory
    Up to 235 °C
    PPS-CF, the hottest we print

    What we decide with it

    Heat is usually the first thing that rules a material out, because a plastic softens well below its melting point. Sunlight and weather rule out some more. Above 235 °C nothing we print holds its shape, and we will say so rather than quote.

    Goes into: Quote form: the heat slider, 20 to 235 °C, or "Not sure". API: notes.

  4. 04

    How much force does it take?

    Find out

    • The closest of the five stops below.
    • If it carries weight: roughly how many kg, and how. Hanging, pressing, twisting or being hit.
    • Which way the force pulls or pushes on the part, if the person can tell.
    None
    a display piece, a model, decoration
    Light
    a cover, a cable clip, a knob
    Everyday
    holders, enclosures, clips that get pulled
    Real load
    brackets, mounts, hooks carrying weight
    Hard use
    tool bodies, vehicle parts, things that get hit

    What we decide with it

    Load decides the material, the number of walls, the infill and which way up we print. An FDM part is strongest along its layers and weakest between them, so knowing the direction of the load lets us lay the layers along it.

    Goes into: Quote form: the force slider. API: notes.

  5. 05

    Looks, or strength?

    Find out

    • The closest of the five stops below. "Both equally" is our default.
    • Which faces are seen once the part is fitted, and which touch another part.
    • Colour, if it matters: a name, a RAL number or a sample to match. If black suits the part, say so: our printers run black PETG around the clock, so it does not wait for a material change.
    Looks only
    surface finish decides it
    Mostly looks
    lean to finish, keep it sound
    Both equally
    our default
    Mostly strength
    lean to strong, keep it tidy
    Strength only
    marks do not matter at all

    What we decide with it

    This answer settles the trades in the next section. It tells us where we may give up surface finish for strength, and where we may not.

    Goes into: Quote form: the looks or strength slider. Faces and colour go in "Technical brief". API: notes.

  6. 06

    Will it touch fuel, oils or solvents?

    Find out

    • Yes or no. Splashes and wiping count. Washing in water does not.
    • If yes, each one by name. The form lists the ones below; anything else goes in by its own name, for example hydraulic oil.
    Petrol or diesel
    Engine oil or grease
    Brake fluid or coolant
    Acetone, IPA or thinners
    Cleaners or detergent
    Acids or alkalis

    What we decide with it

    Chemicals narrow the material sharply. A plastic that copes with the heat and the load can still swell or crack in the wrong fluid, so a person checks each named chemical against the material.

    Goes into: Quote form: "Will it touch fuel, oils or solvents?". API: notes.

  7. 07

    Which dimensions matter?

    Find out

    • Any dimension that has to be held, with its tolerance: a hole for an M4 screw, a slot for a DIN rail, a bore for a bearing.
    • The part it mates with, by name or model number.

    What we decide with it

    Our published tolerance is ±0.5% of the nominal size, and at least ±0.5 mm. If one dimension needs better than that, name it: we can orient the part in that dimension's favour, and we say plainly when it cannot be held.

    Goes into: Quote form: "Technical brief". API: notes.

  8. 08

    When must it arrive, and where?

    Find out

    • The date it must arrive by, and whether that date is hard (a machine is down, an event, a shipment of its own) or a preference.
    • If the date is hard, what may change to make it: another material, or a plainer finish.
    • The delivery country. Every order is posted, to a parcel locker or an address. There is no pickup.

    What we decide with it

    A hard date favours our most popular materials, which usually print 1-3 working days after approval; for anything else the quote gives the time. We check the date before quoting, and the quote names the shipping service and the transit time. The date the person gives is not a delivery promise.

    Goes into: Quote form: "Required arrival date" and "Delivery country". API: country, and the date in notes.

  9. 09

    Where does the price go?

    Find out

    • The person's email address. The form asks it first.
    • A company name or order reference, if they have one.

    What we decide with it

    A person replies to this address with the price. It is not used for anything else.

    Goes into: Quote form: "Email" and "Company or order reference". API: email, and the company in notes.

The trades

What your answers let us choose

Every FDM part is a set of choices, and most of them trade one property for another. These are the ones the answers above settle. If the person has a view on any of them, put it in the brief.

Print temperature

Printing hotter bonds the layers better, so the part is stronger between its layers. Edges and fine detail come out a little less crisp, and overhangs sag more. Printing cooler gives the reverse. Strength usually decides it for a bracket, looks for a cover.

Which way up

Standing a part so the load runs along its layers can need supports, and a support leaves a rough patch where it touched. Laying it for the fewest supports gives cleaner faces and a shorter print, but can put the layers across the load. Knowing which faces are seen lets us put the rough patches where nobody looks.

Layer height

Our standard layer is 0.20 mm. Finer layers give smoother curves and slopes, and take longer to print.

Walls and infill

More walls and denser infill make a part stiffer and heavier. They also use more material and machine time, so the part costs more and takes longer.

The brief

Write it in this shape

Keep it under 5,000 characters, the size of the form's brief field. Write "not sure" where the person does not know, and leave out lines that do not apply.

How the brief reaches us

The person sends it

Open the quote form and answer its screens with the answers above. Paste the brief into "Technical brief" on the part screen. If there is a file and the brief already covers heat, force, finish and chemicals, pick "I have a model and specification" on the first screen: it skips the slider screens.

/quote

You send it, with the person's go-ahead

Post it to the enquiry endpoint described in llms.txt under "Ordering programmatically". The part in one line goes in part_description, the brief in notes, with email, quantity, country and the files.

/llms.txt

Either way, what comes back is a price by email from a person. Sending is not ordering. Do not tell the person their part is ordered, and do not promise a price or a date: the quote does that.

Anything that does not fit the brief: [email protected]
