Quality Assurance
Our team optimizes every print — you focus on selling.
Choose material based on function: PLA for display items, PETG for functional parts that need durability, TPU for flexible items.
Prototype before listing. Print 2–3 iterations to optimize wall thickness, infill, and support placement. Each iteration costs $2–$5 — worthwhile investment.
Design for your print bed size. Standard beds are 220x220mm or 256x256mm. Models that fit a single bed cost less to produce than multi-part assemblies.
Post-processing adds value: sanding (100-400 grit progression), priming, and painting turn a $15 product into a $40+ product.
Use the 2.5x pricing rule to start: Retail Price = Production Cost x 2.5. This gives 60% profit margins with room for promotions.
