Why 3D printing for FBA inventory?

Injection molding locks you into tooling costs and large minimums before you know if a listing will sell. 3D printing lets FBA sellers launch new SKUs fast, restock in small batches to avoid storage fees, and update a design after customer reviews with nothing more than a new file.

Common questions

What does an FBA 3D printing service do?: It manufactures your 3D-printed product and preps it to Amazon's requirements — unit barcodes, cartons, and shipping labels — so inventory goes directly to an Amazon fulfillment center without passing through your hands.
Is there a minimum order quantity?: No. There's no mold or tooling, so you can restock a few units to test a listing or thousands for peak season.
What files do I need?: An STL of the part, your per-unit FBA barcode (PDF or image), and the FBA shipping label PDF from Seller Central.
What is the largest part you can print?: Parts must fit within 220 × 220 × 220 mm. The upload step checks this automatically.
How is pricing calculated?: Per-part print cost from the Slant 3D API for your exact geometry and material, plus a flat handling fee and the boxes needed to pack your run.
