How Long Does 3D Printing Take?

There are two questions hiding in this one. "How long does the print take?" and "when do I get my part?" They have very different answers, and the second is the one you actually care about.

How long the print takes

A rough feel for typical FDM parts:

• A small clip, spacer or fitting — well under an hour.
• A palm-sized bracket or mount — a couple of hours to half a day.
• A large enclosure or a substantial functional part — most of a day, sometimes more.
• A full plate of small parts — most of a day, but that is one job producing many parts.

Prints running overnight are completely normal. Multi-day prints exist and are usually a sign the part wants splitting or redesigning.

What actually drives print time

Height, more than volume. The printer builds one layer at a time, so a tall part means many layers regardless of how little plastic is in each. A part twice as tall takes roughly twice as many layers. This is why orientation changes the estimate so much — laying a tall part down can cut the time dramatically.

Layer height. Halve the layer height for a finer finish and you double the number of layers. Detail is paid for in hours.

Walls and perimeters. More perimeters mean more passes per layer. Worth it for strength, but it costs time.

Infill. Both the percentage and the pattern. Going from a light infill to a heavy one adds real time — and often less strength than you would expect. See what infill should I choose.

Supports. Overhangs need scaffolding, and that scaffolding is printed plastic that takes time to lay down and time to pick off afterwards. A part designed to avoid supports can be substantially quicker.

Small detail and many direction changes. The head accelerates and decelerates constantly on fiddly geometry, so it never reaches full speed. A small intricate part can take longer than a bigger plain one.

Material. ABS and ASA print slower than PLA — no part cooling and a warm enclosure means you cannot push the pace.

What decides when you actually get it

The print is often not the long pole. The full sequence is:

1. File review. We check the geometry, look for thin walls, non-manifold errors and impossible overhangs, and confirm the scale. Usually quick, but if the file has problems it takes a conversation. Our guide on why an STL might not be printable covers what we look for.
2. Design time, if the part needs designing or fixing. This is often the biggest single block of time on a job — days, potentially, and it depends as much on how quickly you can answer questions as on us.
3. Confirming the quote. Nothing starts until you say yes.
4. Queueing. Parts print in order. The machine can only run one plate at a time, and a job already running has to finish.
5. The print itself.
6. Post-processing. Support removal, cleanup, any sanding or finishing. Manual, and it scales with the number of parts.
7. Post or collection.

Realistically, for a straightforward part from a good file, think in terms of a few days rather than hours. Add design work and it stretches. Add a batch with heavy post-processing and it stretches again.

How to make it faster

• Send a clean, printable file. The single biggest saving. Upload it and we will check it before anything else.
• Answer the material and use questions up front. Where does it live, what does it hold, how hot does it get.
• Say what your deadline is. If it is tight, tell us at the start — not after the quote. Sometimes we can reshuffle; a tight deadline can carry a premium if it means displacing other work.
• Accept a coarser layer height if the part is functional rather than cosmetic. It is faster and usually stronger.
• Do not over-specify. Heavy infill and a fine finish on a part nobody sees is time and money for nothing.
• Let us reorient it. The orientation you modelled in is rarely the fastest or strongest one.
• Split large parts. Two halves printed and joined can beat one enormous print, and it fails less often.

Why we do not print instantly

Honest answer: a long print that fails at hour nine has to start again, and a rushed setup is how that happens. The file check and the orientation work exist to stop you paying for that. Getting it right first time is faster than getting it fast twice.
