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.
