For suppliers

Are You a Custom Manufacturer? This Network Was Built for You.

Trustbridge is not another buyer platform with a supplier tab bolted on the side. We are building the infrastructure that manufacturers have always deserved— qualified leads matched to your capabilities, direct buyer relationships, no subscription fees, and no intermediary sitting between you and your customer.

If you run a CNC shop, an injection molding facility, a 3D printing bureau, or a fabrication house and you are tired of bidding wars on unqualified leads, this is where you belong.

And something built specifically for contract manufacturers — something that does not exist anywhere else in the industry — is coming for early network members first.

Frequently Asked Questions — Custom Manufacturing Services


Q1: What custom manufacturing services does Trustbridge offer?

Trustbridge sources custom parts across 3D printing (FDM, SLS, SLA), plastic injection molding, CNC machining, sheet metal fabrication, and metal casting. Urethane and silicone casting is launching soon. Engineering design services including DFM review are available as standalone or combined engagements.


Q2: How does Trustbridge vet its custom manufacturing suppliers?

Every custom manufacturer in the Trustbridge network is individually assessed on process capability, quality certifications, communication, and production history. Suppliers operate across the US, Mexico, India, China, and SE Asia. Buyers only receive quotes from manufacturers who have completed this qualification process.


Q3: How do I submit a custom manufacturing RFQ?

Submit your CAD files (STEP, IGES, STL, SolidWorks, or Fusion 360) along with material, quantity, tolerance, and surface finish requirements through the Trustbridge RFQ form. Our team reviews your submission and routes it to relevant vetted custom manufacturers. You receive multiple competitive quotes to compare.


Q4: Does Trustbridge mark up supplier quotes?

Trustbridge does not introduce hidden costs during the quoting stage. The quotes you receive reflect the manufacturers' actual pricing for your project. Trustbridge's commercial arrangement is with the supplier side of the network and does not affect the figures presented to buyers.


Q5: Can I get DFM review before my custom manufacturing RFQ?

Yes. Design for Manufacturability (DFM) review is available as a paid standalone service before RFQ submission. It is not automatically included — engage it separately or as part of a combined design and sourcing project.


Q6: Does Trustbridge support prototype and production volume custom manufacturing?

Yes. For prototypes: 3D printing and rapid-turn CNC machining. For production: injection molding, high-volume CNC, sheet metal, and casting. Your RFQ is matched to the appropriate supplier type for your specified quantity and stage.
