About J3DB
From Concept to Creation
J3DB started as a small one-room setup — just a printer, a desk, and a few ideas that needed to be brought to life.
What began as a personal hobby quickly turned into something more. From designing and printing parts for myself, friends, and local makers — small things that solved real problems or made projects a bit easier.
Now J3DB offers the same approach to anyone who needs something printed: practical, clean, and reliable 3D prints made with care and attention to detail.
Every project, big or small, gets the same focus — because that’s the kind of service we would want if we were the customer.
Whether it’s a prototype, a replacement part, or just an idea you want to see take shape, J3DB is here to help make it real.
Frequently Asked Questions
Have a question about your project?
Below you'll find answers to common questions about our design and 3D printing services, including file formats, materials, turnaround times, and shipping.
1. How does the design and 3D printing process work?
J3DB reviews your project details, files, or reference material first. If needed, clarification is requested before a quote is prepared. Once the quote is accepted, delivery details are confirmed, the invoice is issued, and production begins after payment is received.
2. How much does a custom 3D printing project cost?
Costs vary depending on the material, part size, print time, complexity, and whether any design work or file adjustments are required. Every project is reviewed individually, and a clear quote is provided before any work begins.
3. What file types do you accept?
J3DB accepts common 3D model formats such as 3MF, STL, STEP, STP, OBJ, and IGES. If you do not have a 3D file, you can also send sketches, photos, measurements, PDFs, or notes to help explain the project.
4. How do I send my project files?
Files can be sent either by uploading a ZIP file through the Start a Project form or by sharing a secure cloud or model link, such as Google Drive, Dropbox, WeTransfer, Thingiverse, Printables, or MakerWorld.
5. Can you print customer-supplied models?
Yes. Customer-supplied models can be reviewed for printability and produced as supplied, or adjusted first if changes are needed to improve fit, strength, or reliability.
6. Can you modify an existing model or design something from scratch?
Yes. J3DB can help with model adjustments such as scaling, hole changes, fitment tweaks, and other practical edits. Design-from-scratch work is also available using measurements, sketches, photos, or a clear description of the part required.
7. How long does a custom 3D printing project take?
Straightforward printing jobs are typically completed within 3 to 7 business days after payment. Projects involving design or more complex preparation usually take around 5 to 14 business days, depending on the work required.
8. When does production begin?
Production begins once the quote has been accepted, delivery details have been confirmed, and payment has been received. If design work or revisions are required first, those are completed before final printing begins.
9. What materials do you offer?
J3DB primarily works with PLA and PETG, which are suitable for many practical and decorative applications. Resin printing can also be arranged through a trusted partner for projects requiring higher detail or smoother finishes.
10. What is the difference between turnaround time and delivery time?
Turnaround time is the time needed to review, prepare, design, print, and complete your project. Delivery time is the courier shipping time after dispatch. These are separate stages and should be considered independently.
