Getting started

What is the Print-Portal?: The Print-Portal is a browser-based workspace where you import 3D models, place them in a build volume, and request a formal quote when you are ready.
What’s the usual workflow?: Open the portal, create or open a project, load models (STL, GLB, or OBJ), scale/arrange them, then sign in to request a quote and upload files. After submission, you’ll receive a confirmation email and can track your request in your account.

Which file types are supported?: The portal supports STL, GLB, and OBJ (with MTL + textures). Upload OBJ as a multi-file selection or as a ZIP bundle (one OBJ package per archive).
What’s the recommended format for full-color?: Our main recommended format is OBJ + MTL + texture images. For best compatibility, keep textures as PNG.
What should a GLB contain?: Keep GLB exports “model-only”: meshes, materials, and textures. Avoid exporting lights, cameras, multiple scenes, or animations.
How do I handle transparent / clear parts?: If you want a part to be transparent/clear, upload it as a separate object. Textures don’t matter for transparent parts—what matters is keeping the clear geometry separate from opaque geometry.

Do you upload my project automatically?: No. Projects live in your browser (local storage/IndexedDB). Saving or editing a project does not upload your model files to Updruck by itself.
What gets uploaded when I request a quote?: When you request a quote, the portal creates a submission and your browser uploads the actual model files using short-lived upload links. In-portal cost estimates are coming soon.
