Frequently asked questions

Most orders ship in 3–5 business days. Large runs and heavily finished parts can take longer — the timeline is always shown before you pay, and you can track every order from print queue to delivery.

First an instant geometric estimate gets a price on your screen in seconds. Then a real slicer runs your part against the actual machine that will produce it, verifying exact print time and material use — that verified number is what you pay. Laser jobs are priced from your file's real cut and engrave path lengths.

Yes, automatically. Discounts scale continuously with quantity on every part — the quote page shows per-unit pricing at 1, 5, 10, 25, 50, and 100 pieces so you can see the curve. Need more than that? Contact us for a production quote.

Send it to us through the contact page with a note about what you need. Multi-part assemblies, oversized parts, unusual materials, and standing production runs are all things we handle directly.

STL, 3MF, and STEP for 3D printing; DXF and SVG for laser cutting and engraving. STEP files are converted automatically, and uploads are analyzed instantly for size, printability, and cut paths.

Dozens of stocked options: PLA, PETG, ABS/ASA, TPU, and carbon-fiber composites for FDM; standard and engineering resins for SLA; plywood, MDF, acrylics, leather, cardboard, and rubber for laser cutting, plus metal engraving. Each material lists its colors and variants on the materials page.

Both. We stock Polymaker filament by the spool — PLA, ABS in plain, Pro and Max grades, ASA, and the fiber-reinforced Fiberon range — split by spool size so the price you see on a listing is the price of that spool, not a range. Browse the filament.

Yes. By default we follow your file — blue strokes or layers named 'engrave' are engraved, everything else is cut. You can also override per job: cut everything, or engrave everything.

They're stored securely, used only to quote and produce your parts, and never shared with anyone. The exact file you approved is frozen with your order so production matches what you saw.

Yes — it's a whole practice. We design and build complete aircraft (quadcopters, hexa/octocopters, coaxials, fixed wing, and VTOL), print crash-replacement parts, and do repairs and tuning. Every build is performance-modeled with our technical partner RotorLab before assembly.

A free configurator. Pick one of 10 airframes — a 112 mm cinewhoop up to a 705 mm hexacopter — and the aircraft is drawn in 3D as you change motors, props, the stack, camera, GPS, radio and pack. Every part in it is something we stock, priced as you go, and the whole build goes into the cart in one click. Open the builder.

They come from RotorLab, our performance-engineering partner, using the same physics we use on real builds — thrust-to-weight, hover time, top speed, prop RPM, voltage sag and ESC headroom at full throttle. The builder also warns you when a combination will not work: pick a pack that cannot supply the current your motors want at full throttle and it says so on the screen, before you buy it.

Yes — tick them in the builder and they're added to the same order. Drone assembly & tune is $149, a bench test & flight report is $79, and pre-binding & radio setup is $39. You can also have the parts shipped and build it yourself.

Only if you don't already own them, which is why both start at "none" in the builder. If you do need them, match the goggles to the video system: our HD air units are Walksnail Avatar, so they need Walksnail goggles — DJI and HDZero goggles cannot see them. Analog goggles go with the analog camera. Every listing says which it is.

The builder marks that line "ask us" instead of pricing it, and leaves it out of the total. Send us the build through the contact link on the builder page and we'll source the part and quote it.

Yes. Our prototyping practice covers microcontroller builds (ESP32, Raspberry Pi Pico, Arduino-class, STM32), sensors and connectivity, and the embedded firmware to run it all — enclosed in a case printed in-house. Describe what the device should do on the Prototyping page and we'll tell you what we'd build it with.

Orders ship from Dubuque, Iowa anywhere in the US and Canada. At checkout you'll see live USPS rates calculated from your cart's actual weight — printed parts use their real sliced material weight, not a guess.

Not through the checkout at the moment. Get in touch with what you need and where it's going and we'll tell you whether we can get it there and what it would cost.

Because pretending they don't exist would be less useful to you. Where a part we resell has reviews on the manufacturer's own listing, we reproduce some with attribution, clearly marked as not ours, and they are not counted in our star rating. Our own reviews are the ones in the main Reviews section.
