3D Printer on Demand does not always answer
Over the last week it answered 29.3% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
print
get_print_quote
Use this when someone wants a quote to have a 3D model (an STL, 3MF, STEP or OBJ file) printed and shipped by 3D Printer on Demand. It reads the attached file, checks that it can be printed, saves the quote, and returns the estimate with a private link that opens the saved quote on our website. When no file is attached, or the file type cannot be read, it returns a link to upload the file on our website. It does not cover drawings or photos.
update_print_quote
Use this when someone wants a different quantity or color on a quote 3D Printer on Demand already gave them. It takes that quote's private link and the new quantity, works out the estimate again from the file saved with the quote, saves it, and returns the new estimate with a new private link. The earlier link keeps the earlier quote. It does not take a new file, a different material, or a link that did not come from one of our quotes.
compare
compare_print_vs_molding
Use this when someone wants to compare 3D printing with injection molding for a quantity, using their own numbers: quantity, printed unit cost, tooling cost and molded unit cost. It returns the totals for each, the crossover quantity on those numbers, and the published range with sources. It makes up no cost, and when a number is missing it says which.
design
get_design_guidance
Use this when someone asks how to design a part for FDM 3D printing: wall thickness, tolerances, hole clearances, overhangs and supports, orientation, infill, bosses, ribs, snap fits, threaded inserts, dimensional accuracy, published material figures, or printing compared with molding or machining. It takes a topic or the question and returns short answers with their published sources and a link to the full page. It does not check a specific file.
materials
list_materials
Use this when someone asks which plastics 3D Printer on Demand prints, which colors each comes in, which material suits a job, or which materials are quoted by a person. It returns each material with what it is for, what it is not advised for, its colors and how it is quoted, plus plain guidance on comparing them. It returns no engineering figures.
printability
check_printability
Use this when someone attaches an STL, 3MF, STEP or OBJ file and wants to know whether it will 3D print well: size, walls, mesh problems and what to change. It reads the file, runs the same automatic design checks as our website, and stores nothing. It gives no quote. When no file is attached, it returns a link to upload the file on our website.
recommend
recommend_material
Use this when someone wants help choosing which of our plastics suits a part, from where it will be used: indoor or outdoor, heat, impact, flexing, chemicals, looks and material cost. It returns the materials we offer that fit, best match first, the reasons in plain words, and the ones ruled out and why. It does not rank materials by strength or stiffness, and it sends safety-critical parts to a person.
service
get_service_details
Use this when someone asks how 3D Printer on Demand works: lead time, shipping, how long a quote is held, accepted file types, the largest part, the items we refuse to print, or where to upload a file, request a review or get in touch. It returns these facts as our website publishes them.
size
size_hole_or_tolerance
Use this when someone asks what clearance or hole size to draw for a printed fit: a sliding part, a bolt or pin through a hole, two printed parts that mate, a press fit, or a snap fit. It returns published starting clearances and hole guidance, each with its source, and how to test the fit. It gives no single universal hole offset, because none is published.

3D Printer on Demand — questions
Answers built from our own checks of this server.
What can 3D Printer on Demand do?
It exposes 9 tools, read directly from the server on our last check. Among them: check_printability, compare_print_vs_molding, get_design_guidance, get_print_quote, get_service_details, list_materials and 3 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is 3D Printer on Demand working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 7 of 92 checks got a reply (7.6%), average response time 437 ms. The bar chart above shows every period we have measured.
The registry lists 3D Printer on Demand as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect 3D Printer on Demand?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does 3D Printer on Demand need an API key?
No. 3D Printer on Demand completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is 3D Printer on Demand?
It answers our handshake in 437 ms on average, which is faster than 27% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
