Online 3D Printing Services: How to Order a Print and What It Costs
No 3D printer, a part too big for yours, a material your machine can’t handle, or metal? An online 3D printing service makes the part from your file and ships it to you. Here is how ordering works, what drives the price, the kinds of services available to individuals, and when buying your own printer makes more sense.
Key takeaways
- Upload a 3D file (STL, 3MF or STEP), pick material and finish, and get an instant quote.
- Price depends mostly on material volume, technology and finish, plus shipping.
- For a one-off part or metal, a service is often simpler. If you print regularly, an entry-level printer pays for itself quickly.
- Orders made abroad can mean longer delivery and import duties or taxes.
When to use a printing service
- You don’t own a printer and need one or two parts: a replacement part, a prototype, a gift.
- The material is beyond a home printer: sintered nylon (SLS or MJF), metal, engineering resins.
- The part is too big for your printer or must be one piece.
- You want a professional finish: dyeing, polishing, bead blasting, painting.
- You need a small batch of identical parts with consistent quality.
How to order, step by step
- Prepare the file. Download a model (see free 3D model sites) or design it. Services usually accept STL, often 3MF, OBJ or STEP too. Check the units (millimeters or inches) and the scale.
- Upload it. The service analyzes dimensions, volume, too-thin walls and mesh errors.
- Pick technology, material, color and finish. The price updates live.
- Compare lead time and shipping: production time plus transit, and where the part ships from.
- Order and follow production. Some services check files by hand and contact you if there is a problem.
Technologies and materials
| Technology | Typical materials | Strengths | Best for |
|---|---|---|---|
| FDM (filament) | PLA, PETG, ABS, ASA, TPU | Cheapest, large parts possible | Simple parts, prototypes, brackets |
| SLA / resin | Standard, engineering, clear resins | Very fine detail, smooth surface | Miniatures, jewelry, precise parts |
| SLS / MJF (powder) | Nylon (PA12, PA11), TPU | Strong, functional parts without supports | Mechanical parts, clips, hinges, small batches |
| Metal | Stainless steel, aluminum, titanium | Complex metal parts | Technical parts, industrial prototypes |
For most individuals, the choice is between FDM (cheapest), resin for miniatures, and SLS or MJF nylon for parts that must be tough. Metal costs much more.
What drives the price
- Material volume: the biggest factor. A hollow or lightweight part costs less than a solid one of the same size.
- Bounding box: for SLS and MJF, the space the part takes in the machine matters too.
- Technology and material: from PLA on FDM to metal, the price can rise tenfold or more.
- Finish: dyeing, polishing or painting add to the base price.
- Minimum order and shipping: many services have a minimum order or fixed fees that weigh heavily on a small part.
- Quantity: the unit price often drops for several copies.
In practice, a small simple plastic part often costs a few dollars to a few tens of dollars before shipping, and a metal part considerably more. The only reliable price is the instant quote you get by uploading your file, which is free on most sites.
Types of services
Online manufacturing services and marketplaces
Platforms such as Xometry and Protolabs in the US offer instant online quotes for plastic and metal 3D printing, often alongside other manufacturing methods. Comparison platforms such as Craftcloud show prices from many partner workshops for the same file in one click. Check where the chosen workshop is located: lead time, import costs and support depend on it.
Overseas workshops
Services such as JLC3DP print in China, often at low prices. In return: longer shipping, and possible import duties, tariffs or taxes on delivery depending on your country’s current rules. Worth it for non-urgent parts if you calculate the total cost.
Libraries, makerspaces and schools near you
Many public libraries, makerspaces and university or community college labs offer 3D printing, sometimes with help from staff. It’s an inexpensive way to get a part printed and to learn before buying your own machine. Search for “3D printing” plus your library or city: access, hours and prices vary a lot.
We are not partners of any of these services and have not tested them: compare quotes, lead times and terms before ordering.
Pitfalls to avoid
- Wrong scale: a model designed in inches but read as millimeters arrives 25 times too small. Always check the dimensions shown after uploading.
- Walls too thin: each technology has a minimum thickness. Services usually warn you, but not always.
- Forgetting the total cost: shipping, minimum order, and duties or taxes for overseas orders.
- Model rights: having a non-commercial model printed for yourself is generally fine; reselling the parts may not be. This is not legal advice.
Service or your own printer?
| Online service | Printer at home | |
|---|---|---|
| Upfront cost | None | Roughly $200 to $300 for a good start |
| Cost per part | Higher (labor, margin, shipping) | Cents to a few dollars of filament |
| Lead time | Several days including shipping | A few hours |
| Materials | Wide choice, including sintered nylon and metal | PLA, PETG, TPU, plus ABS and ASA with an enclosure |
| Best for | One-off parts, engineering materials, metal | Regular printing, experimenting, hobbies |
If you expect to print more than a few parts a year, an entry-level printer pays off quickly. The printer finder helps you choose, and our beginner’s guide explains the basics.
FAQ
How much does online 3D printing cost?
It depends on the part’s volume, the technology, the material and the finish. A small simple plastic part often costs a few dollars to a few tens of dollars before shipping; metal costs considerably more. Upload your file for an exact quote.
Where can I get something 3D printed near me?
Many public libraries, makerspaces and university labs offer 3D printing, often at low cost and sometimes with help from staff. Access and prices vary, so check with your local library or makerspace.
What file do I need to send?
A 3D file, usually STL, sometimes 3MF, OBJ or STEP. Make sure the units are correct and that the dimensions shown after uploading match the part you want.
Can I get a part printed in metal?
Yes, several online services print in stainless steel, aluminum or titanium. It costs much more than plastic, and the design rules (wall thickness, supports) are stricter.
