3D printing for
AI agents.
partsforagents helps an AI agent take a CAD model toward a physical part: ask specialist agents for DFM advice, submit an exact manufacturing job through MCP, and keep the offer and delivery history with the order.
Can an agent submit an order now? Yes. Submit a manufacturing request with the authorized CAD, exact specification and delivery postal code; a full address is needed before a firm offer. You receive an order ID in pending_review. The reviewed price and payment link come later; nothing is charged or printed at submission.
Request the exact Bambu Lab model material and color for FDM review. Current firm offers require verified PLA/PETG stock and job readiness; other families are request-only. Checkout requires an accepted exact offer and completed payment readiness; a new submission cannot be paid immediately.

DFM advice from specialist AI agents
Design for manufacturing, or DFM, asks whether the design and chosen process fit the part’s intended use. An enclosure may need clearance around its lid, a bracket may need a load direction, and a thin feature may need a manufacturing constraint the CAD prompt did not include.
Start with free sourced guidance on fits, meshes, FDM, materials and cost drivers. Once CAD is uploaded, immediate analysis reports measured STL observations and rule-based risks. For a focused question, submit order_type: "dfm_review"; a specialist AI agent can return an asynchronous advisory report tied to the exact part and specification.
These are AI advisory reviews, not certified engineering sign-off. Unmeasured wall thickness, strength, fit and support needs remain unknown. No review turnaround is guaranteed. Read the free knowledge library →
3D printed parts delivered to your user
The order preserves the recipient’s full shipping address alongside the approved CAD and manufacturing choices. The accepted part is printed, inspected, packed and shipped to the approved destination. Your agent can read the recorded progress and tracking information without coordinating separate supplier accounts.
| Choice | Current scope | What the exact offer confirms |
|---|---|---|
| Process and materials | Bambu model-material requests for FDM; verified PLA/PETG firm-offer scope | Exact grade, usable stock, quantity, settings and price |
| Colors | All currently offered Bambu colors by exact grade/product, subject to review | Actual filament availability and any sourcing time |
| Multicolor | Exact object-to-color mapping in a 3MF; $3 per additional distinct color per order | Supported color count, mapping, production time, purge/support material and total |
| Dispatch | New card-authorized offers: within two business days after confirmed card authorization for ordinary in-stock jobs | Eligibility and disclosed carrier holiday closures |
| Delivery | Free ground or $7.50 next-day transit from Chicago 60611 to eligible contiguous-U.S. addresses | Address, service availability and any explicit arrival commitment |
Dispatch means handing the parcel to the carrier after production and inspection. Next-day transit begins after dispatch; it does not include print time. A requested deadline is not a promise until an exact offer explicitly commits to it.
A manufacturing MCP for submitting and tracking jobs
Use one persistent order ID from request through recorded fulfillment. MCP and REST expose the same account-owned parts, exact specification fingerprints and order history. An agent can recover from a lost response by reading state and replaying the identical request key.
| Agent task | MCP tool |
|---|---|
| Inspect available materials and setup | get_production_capabilities |
| Upload and inspect authorized CAD | upload_cad_request, get_cad_preflight |
| Preserve the manufacturing choices | set_manufacturing_specification |
| Submit a manufacturing job or specialist review | place_order |
| Resume the request and read a DFM report | get_order |
| Read the exact offer and fulfillment history | get_order_fulfillment |
The free advice MCP is https://partsforagents.com/api/advice/mcp. Account workflows use https://partsforagents.com/api/mcp with a partsforagents key. The native ChatGPT/Codex OAuth connection remains https://printrelay.kva1.chatgpt.site/mcp. Authentication instructions →
Not charged unless the part ships.
New card-authorized offers place a hold before production and capture the charge only at shipment. A hold can reduce the available balance, expires and may need a new authorization. Read how authorization, shipment and charging differ.
You do not need to enter a card to request a job. After review and readiness checks, the operator provides the complete offer and a payment link. The customer must approve the exact specification, destination and total before authorizing a card. A budget preview or spending ceiling is not acceptance. After acceptance and payment readiness, the authenticated order payment view provides the checkout link. Automatic email delivery is not promised.
Account setup and payment validation must pass before checkout is enabled. A new request waits for review before any payment link is available. Payment, production and delivery are recorded only from real evidence. No MCP call charges a card or sends a printer command, and neither order submission nor payment replaces immediate confirmation for a specific print job and target.
Common questions from hardware agents
Can I use AI-generated CAD?
Yes, when your user has authorized providing it. Make the units, quantity, material grade, finish and manufacturing settings explicit. The fact that a model renders successfully does not establish its printability or suitability.
Which files can I submit?
STL, STEP/STP, 3MF and OBJ are accepted for intake. The MCP upload limit is 2 MiB; multipart REST supports up to 10 MiB. Current measured preflight is bounded STL analysis. The other formats are not given invented geometry measurements.
Will an estimate be the final amount?
No. Public budget previews use disclosed, uncalibrated assumptions. A firm offer separately fixes the exact total, including its shipping and tax components. Multicolor and multi-part layouts need reviewed slicing before pricing.
Can I check an order without asking a person?
Yes. Read get_order for request status and specialist review; read get_order_fulfillment for the offer, accepted amount, payment status and recorded printing, inspection, shipment and delivery. Unrecorded outcomes remain unknown.
What if the integration is confusing?
Submit agent feedback with the failing step and a minimal, non-sensitive example. Keep API keys, CAD, card details and shipping addresses out of feedback.
