Based in Grand Rapids, MI — the manufacturing capital of the Midwest — Granjure was founded on the belief that additive manufacturing can transform how American industry builds products.
Granjure was born in Grand Rapids, Michigan — a city with over 150 years of manufacturing heritage. Our founders recognized a gap: world-class additive manufacturing capabilities were concentrated on the east and west coasts, leaving Midwest manufacturers without a trusted local partner.
We set out to change that. With a state-of-the-art facility in West Michigan and a team of engineers deeply embedded in the local industrial community, Granjure delivers AM solutions with the technical depth of a national provider and the responsiveness of a true regional partner.
Our Innovate · Connect · Grow strategy guides every engagement — from a first prototype to a long-term production contract.
Every part, every layer, every tolerance matters. We hold ourselves to aerospace-grade quality standards across all work.
We're not a vendor — we're an extension of your engineering team. Your success is our success.
Rapid iteration cycles and responsive communication keep your projects on schedule, every time.
Continuous investment in the latest equipment, materials, and process certifications ensures cutting-edge capability.
Proud to contribute to West Michigan's industrial legacy and support the regional manufacturing ecosystem.
Additive manufacturing by nature reduces material waste. We amplify that with responsible sourcing and recycling programs.
Centrally located in West Michigan, we're within one-day shipping of most major Midwest manufacturing hubs — Detroit, Chicago, Cleveland, and Indianapolis.
From initial design consultation through final inspection, Granjure provides a complete additive manufacturing workflow under one roof in Grand Rapids, MI.

Granjure reserves the right to modify, suspend, or discontinue any service at any time with reasonable notice and may decline to quote or fulfill any Order at our sole discretion.
Quotes are estimates valid for 30 days and may be revised if Design Files are modified, material costs change, or additional technical complexity is discovered.
Order Confirmation: An Order is confirmed only upon Granjure's written acceptance and receipt of payment or approved credit terms. Verbal agreements do not constitute a binding Order.
Cancellations & Changes: Order changes before manufacturing begins will be accommodated where possible. Once production has started, cancellation fees may apply to cover materials and labor incurred.
Lead Times are estimates and may vary due to equipment availability, material supply, or technical complexity. Granjure is not liable for delays caused by factors outside our reasonable control.
All prices are in U.S. dollars. Prices exclude applicable taxes, shipping, or duties, which will be itemized at checkout.
Your Design Files: You retain all intellectual property rights in Design Files you submit. By submitting them, you grant Granjure a limited, non-exclusive, royalty-free license to use and process the files solely to fulfill your Order.

File Accuracy: You are responsible for the accuracy, completeness, and printability of your Design Files. Dimensional or structural deficiencies resulting from Design Files are the Customer's responsibility.
DfAM Reviews: Granjure may perform a courtesy design review to flag obvious printability issues. This review does not guarantee that the Part will meet your functional or aesthetic requirements.
Tolerances: Unless a written tolerance specification is included with the Order, Parts will be manufactured to Granjure's standard process tolerances, available upon request.
Reprints: If a Part fails to meet agreed specifications due to a Granjure manufacturing error (not a Design File issue), we will reprint the affected Part at no additional charge, provided you notify us within 14 days of delivery with supporting documentation.
Granjure treats your Design Files as confidential and will not disclose them to third parties except as necessary to fulfill your Order or as required by law. All manufacturing partners are bound by confidentiality obligations.
If you require a formal Non-Disclosure Agreement (NDA) before submitting proprietary files, contact us at legal@granjure.com prior to submission. We are happy to execute a mutual NDA.
Granjure does not warrant that the site will be uninterrupted or error-free, that Parts will be suitable for any specific end-use application without independent testing, or that material properties of printed Parts will exactly match bulk material specifications.
