A key factor for 3D printing pricing Optimizing printing layout brings relevant advantages More and more platforms providing 3D printing services are appearing online recently. Their workflow is fairly standard: the user logs into the platform, uploads his 3D model (in a compatible format), chooses some operations (e.g. scaling) and features (e.g. material or surface finishing) and finally proceeds to the payment to complete the purchase. Determine an accurate pricing algorithm is vital for these companies, given they don’t have very large margins and a growing number of competitors.
