The cost of 3D printing something depends mostly on two things: whether a 3D model already exists, and how long the part takes to print. If you have a ready-to-print file, you're mainly paying for machine time and material. If you only have a broken part, a sketch or an idea, someone has to design the model first, and that design time is usually the biggest part of the price.
At Print Pros 3D, replacement parts start from $40 and designed prototypes start from $199. Every quote is free, and you approve the price before anything is printed. The rest of this post explains what moves a price up or down, so you know what to expect before you ask.
What you're actually paying for
A 3D printing quote is usually a mix of five things:
- Design or modeling time. Turning a photo, sketch or broken part into an accurate 3D model.
- Machine time. How many hours the part ties up a printer.
- Material. The plastic itself, plus any support material that gets removed.
- Setup and cleanup. Preparing the file, removing supports and checking the part.
- Finishing. Optional sanding, smoothing or painting for parts that need to look polished.
The biggest factor: do you have a 3D file?
This one question changes the price more than anything else.
You have a file (STL, 3MF, STEP or OBJ)
If the model is already designed and printable, the job is mostly preparation and print time. This is typically the least expensive way to get something made. It still helps to have someone check the file first, since a model downloaded from the internet isn't always sized or built to print well.
You have a broken part, photos or a sketch
Here the part has to be measured and modeled before it can be printed. Simple shapes like a spacer or bracket go quickly. Parts with clips, threads, curves or tight fits take longer to get right. The upside: once the model exists, extra copies are much cheaper because the design work is already done.

Size and print time
People often assume material is the main cost, but for most small parts the plastic is a small slice of the price. Time is what matters. A bigger part, a very detailed part or one printed slowly for strength can occupy a printer for many hours. Tall parts and parts with lots of overhangs also need support structures that have to be removed by hand.
Tip: If a part only needs to be strong in one spot, say so. A shop can often reinforce that area instead of making the whole part heavier and slower to print.
Material choice
We print in four common plastics, and each one has a place:
| Material | Typical use | Relative cost |
|---|---|---|
| PLA | Models, indoor parts, early prototypes | Lowest |
| PETG | Functional clips, brackets, mounts | Low |
| ASA | Outdoor and car parts, heat and sun exposure | Higher |
| TPU | Flexible gaskets, bumpers, grips | Higher |
ASA and TPU are trickier to print well, which is why they usually cost a bit more. The right choice depends on where the part lives. Our materials guide covers this in more detail.
Quantity
The first part is always the most expensive per piece, because it carries the setup and any design work. Additional copies of the same part cost noticeably less each. For larger runs, businesses can ask about volume pricing on bulk orders.
Is 3D printing cheaper than other options?
For one-off parts and small batches, usually yes. Traditional methods like injection molding need a custom mold before the first part exists, and that mold is a large upfront cost that only pays off over big production runs. 3D printing skips the mold, so you pay for the parts you need, and changing the design costs an edit rather than a new tool.
Whether it's cheaper than buying a replacement depends on the part. If the manufacturer still sells it at a fair price, buying it may make sense. If it's discontinued, back-ordered or only sold as part of a much bigger assembly, printing just the piece you need is often the better deal.

How to get a more accurate quote
- Send your file if you have one. STL, 3MF, STEP or OBJ all work.
- No file? Send clear photos from several angles, with a ruler or coin for scale.
- Include key measurements like hole spacing, thickness and overall size.
- Say where the part will be used: indoors, outdoors, in a car, near heat or under load.
- Mention quantity so the price reflects any savings on multiples.
- Mail the broken part if it's hard to measure. Having it in hand makes a precise fit much easier.
