General
What industries do you serve?
We work with clients across medical and dental, architecture and scale modeling, engineering and industrial manufacturing, and product design and prototyping. Our materials and technologies are selected to meet the specific requirements of each sector, including biocompatible resins for medical applications.
What is the difference between 3D printing and traditional manufacturing?
3D printing builds parts layer by layer from a digital file, while traditional methods like injection molding or CNC machining remove material from a block or use molds. 3D printing excels at complex geometries, rapid iteration, and low-volume production without tooling costs. Traditional manufacturing is typically more cost-effective at high volumes above 500 units.
Do you offer design assistance?
Yes. Our Design Review and Optimization service includes engineering analysis before production. We check your files for printability, suggest improvements for strength or cost reduction, and help you select the optimal technology and material for your application.
Do you sign NDAs or confidentiality agreements?
Yes. We understand the importance of protecting your intellectual property. We are happy to sign your NDA or provide our standard confidentiality agreement before you share any files or project details.
Where is 3D On Demand located?
We are based in the Netherlands with in-house production facilities. We ship throughout Europe and internationally, ensuring fast delivery times for customers across the continent.
Ordering
How do I place an order?
Simply upload your 3D CAD file on our website to receive an instant quote. Select your preferred material, technology, quantity, and finish. Once you confirm, production starts immediately. You can also contact us directly for complex projects that require a custom quote.
What file formats do you accept?
We accept STEP, STP, STL, OBJ, 3MF, and IGES files. For best results, we recommend STEP files as they preserve the original CAD geometry. If you only have a 2D drawing or another format, contact us and we will help you find a solution.
How does your instant quoting system work?
Upload your CAD file and our system automatically analyses the geometry, calculates material usage, and generates a price based on your selected technology, material, and quantity. The quote updates in real time as you adjust specifications. No account or commitment is required.
Is there a minimum order quantity?
No. We handle everything from a single prototype to batches of 500+ parts. Our on-demand model means there is no minimum order quantity — you pay only for what you need.
Can I order multiple parts in different materials?
Yes. You can upload multiple files and configure each part with its own material, technology, and finish. Everything ships together in a single order, which saves on shipping costs and simplifies your procurement process.
Materials
Heading
We offer Nylon PA12 and PA11, biocompatible resins (ISO 10993 certified), standard and engineering photopolymer resins, and FDM thermoplastics such as PLA, PETG, ASA, and ABS. Contact us for the full materials list.
Which material is best for functional prototypes?
For mechanical stress resistance, we recommend Nylon PA12 via SLS or MJF. For fine detail or transparency, SLA resins are a better fit. Our team can advise based on your specific requirements.
Which material is best for functional prototypes?
For functional prototypes that need mechanical stress resistance, we recommend Nylon PA12 via SLS or MJF. It offers excellent strength, flexibility, and chemical resistance. For fine detail or transparency, SLA resins are a better fit.
