Frequently Asked Questions

Upload your STL or STEP file, configure your print settings (filament, quality, infill, etc.), add to cart, and checkout. We accept all major credit cards via Stripe — no card data is stored on our servers.

Yes. Upload and configure each part separately, then add them all to your cart. Each part can have different settings (different filaments, quality levels, etc.).

Orders can be cancelled within 1 hour of placement, before printing begins. Once printing starts, cancellation is not possible. Contact us immediately if you need changes.

You can check out as a guest. However, creating a free account lets you track orders, save addresses, and reorder easily.

We accept .STL and .STEP (also .STP) files. STL is the universal 3D printing format. STEP preserves full parametric geometry from CAD tools like Fusion 360, SolidWorks, and FreeCAD.

We run automated geometry validation on every upload. If your model has non-manifold geometry, degenerate faces, or structural issues, we'll flag them immediately with a description of the problem so you can fix and re-upload before paying.

Up to 100 MB per file. If your file is larger, try reducing polygon count in your CAD software or contact us for bulk arrangements.

Our build volume is 300 × 300 × 350mm. Larger parts may be split and bonded — contact us for a custom quote.

PLA/PLA+ is great for most general-purpose prints — easy to work with, good detail. PETG is stronger and more heat-resistant. ABS/ASA for high heat or outdoor use. Nylon for high-strength, wear-resistant parts. Visit our Materials page for full comparisons.

Food-safe printing depends on both filament and post-processing. Some of our PETG and food-grade PLA options are manufactured for food contact, but 3D-printed parts are generally not recommended for repeated food contact due to layer gaps that can harbor bacteria. We mark food-safe capable materials clearly in our catalog.

Price is based on estimated material weight (grams), print time, filament type, and quality settings. You'll see a live estimate as you configure your part — no surprises at checkout.

Yes, where applicable. Tax is calculated based on your shipping address and the applicable US state tax rate. Tax is displayed at checkout before you pay.

No. Payments are processed via Stripe. We never see or store your card details. Only your order total and Stripe's charge confirmation ID are stored on our end.

Yes — we run periodic campaigns with coupon codes and automatic promotions. Sign up for our newsletter or check the home page for current offers.

We ship via UPS, USPS, and FedEx. At checkout, you'll see real-time rates from available carriers and can choose the speed and price that works for you.

Currently US-only. International shipping is on our roadmap — if you're outside the US, check back soon.

Once your order ships, you'll receive a tracking number by email. You can also view live status and tracking in your order history.

Draft — fastest, visible layer lines, good for prototypes. Standard — the best everyday balance of speed and finish. Fine — smooth surfaces, good for display pieces. Exact layer height varies by nozzle size (we run 0.4–0.8mm nozzles) — you'll see the precise value for your printer when you configure your part.

We stand behind our quality. If your print has a defect (not user design errors), contact us within 7 days with photos and we'll reprint it at no charge.
