How to get something 3D printed without a 3D printer
Step 1: get a 3D file (or skip it)
A 3D printer needs a 3D model of your part. You have four ways to get one:
- Design it yourself in a CAD program (Tinkercad is free and simple; Fusion, Onshape and SolidWorks for engineers) and export an STL or STEP file.
- Download one from a model site such as Printables or MakerWorld: replacement knobs, hooks, organizers, figures and much more. Check the model’s license if you want it printed by a service. See where to find models.
- Make a simple part from a template: plates, brackets, spacers, washers and boxes can be made by typing their sizes in ply’s Parts Builder, no CAD needed.
- Have it designed: freelance designers and engineering firms can model a part from a sketch, a photo or a broken original.
Step 2: choose where to print it
Online 3D printing services
Upload your file, choose a material and color, and see the price instantly. Some services are marketplaces that pass your order to a partner print shop; others, like ply, print everything in their own facility. Good for: anyone with a file, any quantity, parts shipped to your door. Things to compare: materials and colors offered, whether someone checks your part before printing, the delivery date shown before you pay, and the return policy.
Local print shops and engineering firms
Many towns have a 3D printing business that quotes by email or phone. Good for: talking a part through in person, picking it up the same day when they have time, or parts that also need design work.
Libraries, schools and makerspaces
Many public libraries and makerspaces have 3D printers you can use or ask staff to run, often for a small fee per gram. Good for: small PLA parts and learning how 3D printing works. Expect a queue and a limited choice of plastics and colors.
Buying your own printer
Worth it if you’ll print often and enjoy tinkering. For one part, or for engineering plastics, resin and large parts, a service is usually simpler.
Step 3: pick a material
PLA is the everyday choice for indoor parts and models. PETG is tougher and handles more heat; ASA holds up outdoors; TPU is flexible; carbon fiber plastics are stiff and light; resin gives fine detail and smooth surfaces. Not sure? Describe what the part does and ply’s advisor suggests one, or see every material compared.
Common questions
Where can I get something 3D printed?
Online 3D printing services (upload a file, see a price, get the part by mail), local print shops and engineering firms, and public libraries, schools or makerspaces with their own printers.
Do I need a 3D file?
Usually yes: an STL, STEP, OBJ or 3MF file. If you don't have one, you can download a ready-made model from a model site, have one designed, or, for simple parts like plates, brackets and boxes, make one from a template on a service such as ply.
How much does it cost to get something 3D printed?
It depends mostly on the part's size, the material and how long it takes to print. Online services with instant quotes show the exact price as soon as you upload your file, before you order.
How long does it take?
Online services typically print and ship within days; many show the arrival date before you pay. Local shops and libraries depend on their queue.
