3D Printer on Demand
ChatGPT plugin3D print cost and design help
Ask what you would ask a print shop. How much does it cost to 3D print this? What wall thickness should I use? PETG or PLA for outdoors? Is printing cheaper than a mold for 500 parts? 3D Printer on Demand answers right in the chat.
Attach an STL, 3MF, STEP or OBJ file, or paste a link to a model page or a file. You get a price for your material, color and quantity. Want a check first? We flag thin walls, parts that are too big and mesh problems, and say what to change.
No file yet? Ask a design question. You get guidance on walls, holes, fits, tolerances, supports, snap fits and threaded inserts, each with its published source. Tell us where the part will be used, and we suggest a material from the ones we print. Give us your own costs, and we compare 3D printing with injection molding for your quantity.
When you want the part made, the quote is saved to a private page on 3dprinterondemand.com. There you can see the part in 3D, change the quantity and order. Checkout is on our website. Already ordered? Paste the order link from your email to see where your order is, or to order the same parts again.
Parts are made in the USA and ship within the United States. We do not print firearms or firearm parts, weapons, or the other items in our content policy. Some materials and large parts are quoted by a person, and you are told when that applies.
