Indicative USD and production-only windows for suitable parts with approved CAD, material and capacity. Transit, testing and finishing can add time. Sampling, engineering and setup may carry charges; CAD changes require a fresh DFM review. TPU and complex parts need separate scheduling.

No CAD needed to compare routes. Add an STL, OBJ or supported 3MF to see local bounds, mesh volume and material-weight reference here.

The 24-hour review starts when the required files and specifications are received. Your engineer confirms timing for complex projects; if inputs are incomplete, we first identify what is needed.

First-order validation

First Production Order? Validate Physical Quality Before Committing to Batch Production.

Work directly with our engineering and manufacturing team through a controlled validation workflow: approve physical samples, agree acceptance criteria and release payments at written milestones.

01
Pre-Production Golden Sample (100% Credited to Batch)
Order 1–5 physical samples in your specified production material—PLA+, PETG, PETG-CF, ABS, ASA or TPU—and surface finish. Pay for sample validation first; 100% of the sample fee is credited toward your first batch order of 500+ units.
02
Written Acceptance & QC Checklist
Before batch printing, lock critical tolerances (for example, ±0.2 mm where agreed for the specific part), Pantone or filament color references, applicable insert pull-test requirements and packaging drop-test specifications in writing. Your approved drawing, sample and inspection plan define acceptance.
03
Milestone Payment & Pre-Shipment Video Inspection
Set pilot and batch payment milestones in the written order: for example, a deposit after sample sign-off and the final balance after you review high-resolution batch QC photos, caliper readings and live packing video. Confirm the review appointment and release criteria before production.

Your quotation records the sample fee, the 100% credit against the first 500+ unit batch, the agreed QC evidence and payment milestones. Request PayPal or a commercial invoice; available payment methods, currency and beneficiary are confirmed in writing before payment.

Engineering deliverables

What You Receive Before Batch Release

From engineering review and golden sample approval to shipment sign-off, each checkpoint gives your team a clear record to review. Your engineer confirms document and inspection scope with your quotation.

DFM & Printability Brief

Before sample production

Build orientation: Recommended printing direction for strength, visible surfaces and support removal.
Walls & overhangs: Critical wall thickness and overhang checks, with proposed design adjustments.
Seam placement: A seam strategy agreed against visible and mating surfaces.
Dimensional targets: Estimated tolerance range, e.g. ±0.15 mm or ±0.2%; confirmed per critical feature, drawing and sample.

Golden Sample Approval Sheet

Before batch release

Revision lock: Documented slicer profile and revision tied to the approved sample.
Material traceability: Filament lot and color code recorded for the agreed production specification.
Hardware & fit: Insert torque or assembly fit checks against agreed acceptance criteria, where applicable.
Cosmetic standard: Approved visible surfaces, seam locations and cosmetic acceptance boundaries.

Pre-Shipment Batch QC Record

Before shipment approval

Dimension sampling: A table of critical dimensions, drawing limits, sampled results and inspection status.
Visual & assembly checks: Surface and assembly verification photos for the agreed inspection scope.
Packing list: Carton or tray quantities, part references and packing configuration.
Release review: Review the agreed QC and packing records before final balance settlement, per written payment terms.
