Quoting, slicing, printing, and shipping — explained. No guessing, no back-and-forth emails.
Drop your STL, OBJ, or STEP file directly on the homepage. We accept any 3D print–ready geometry up to a 256×256×256mm bounding box.
Your model loads onto a virtual 256×256mm build plate. Rotate, zoom, and inspect it against the print volume. If your order requires multiple plates, you can step through each one to see exactly how parts will be arranged.
Pick material, color, infill density, layer height, wall count, and supports. The quote, filament weight, and print time update instantly as you adjust. Bulk discounts kick in automatically at 3, 6, 12, 25, and 50 units.
Enter your ZIP code and we calculate USPS Ground Advantage, Priority Mail, and Priority Express rates based on actual current zone pricing — plus state sales tax. No "calculated at checkout" mystery charges.
Place the order, receive a confirmation, and we start printing. You'll get an email when your parts ship with a USPS tracking number. Standard production begins within 1 business day; rush orders prioritize ahead of standard queue.
Your STL is parsed in-browser using the signed tetrahedron method — the same math slicers like PrusaSlicer and Bambu Studio use. We measure exact volume, not file size.
Printed material = walls + top/bottom + infill % of the remaining interior, multiplied by material density. Walls are calculated from your perimeter count and the 0.4mm extrusion line width.
Volume ÷ extrusion flow rate (speed × layer height × line width) plus 25% overhead for travel moves and acceleration ramps, plus setup time between plates for multi-plate orders.
Parts are arranged on the 256×256mm plate with 8mm spacing for support material clearance. Effective packing density is around 62% of plate area, matching real-world slicer arrangements.
USPS divides the country into 9 zones based on distance from origin. We use your ZIP code to look up your zone and apply USPS Ground Advantage retail rates (April 2026 schedule, $7.90 minimum).
Your ZIP code maps to a state, which has a known base sales tax rate. Local taxes (county/city) vary and may apply at fulfillment; we'll notify you if the rate changes.
How a part is oriented on the build plate changes its strength, surface finish, and how much support material it needs. A few things to know before you upload so your part comes out the way you expect.
We print your model in the exact orientation you upload it. If a specific face needs to be smooth, flat on the plate, or pointing up, rotate the part that way in your CAD or slicer before exporting. We don't re-orient files for you — the orientation you send is the orientation we print.
Beyond generating support structures where the geometry requires them, we don't alter your file — no hollowing, rescaling, wall thickening, or reshaping. What you design is what gets printed. If a feature needs changing, that's a design decision we leave to you.
An overhang is any surface that leans outward more than about 45° from vertical. Below that angle each layer is only partly supported by the one beneath it, so steep overhangs will sag or curl unless supports are added underneath them. Orienting the part to reduce steep overhangs means fewer supports and a cleaner finish.
A bridge is a flat span of material printed horizontally between two raised points with nothing beneath it — think the top of a doorway or a horizontal hole. Short bridges print cleanly; long ones droop in the middle. Reorienting or adding supports helps, and designing spans as arches instead of flat bridges prints far better.
If your part needs support in a specific spot, you can design it in yourself so it detaches cleanly. Leave a small gap — roughly 0.2–0.4mm — between the support and the surface it touches so it snaps off without marring the finish. Too tight and it fuses to the part; too loose and it won't hold the overhang up.
The same thinking applies to parts that fit together (lids, pins, hinges). Plan a clearance of about 0.2–0.5mm between mating surfaces so pieces assemble without forcing. Prints come out very close to your dimensions, so gaps that look fine in CAD but are 0mm wide will end up fused together.
