摘要
针对Shapeways 3D打印平台的机械空间算法在材料费用方面计算精度的不足,提出一种产品蒙皮加厚方法。该方法结合符号距离场与偏置法对产品进行蒙皮加厚,建立了一种更精确的材料费用计算模型。在考虑材料成本和制造成本的基础上,建立了一套面向3D打印平台的产品报价流程及方案。通过实例验证了所提方法的有效性和可行性。
Aiming at the inaccurate material quotation problem of Shapeways 3D printing caused by rough calculation on material volume with machine space algorithm, a skin thickening method was presented by combining signed dis-tance field with offset method. Thus, a new material cost calculation model was constructed precisely with the thickening method. Based on considering of material cost and manufacturing process cost, a set of product quotation scheme was established for 3D printing platform. A quotation process was presented,and some cases were given to verify the feasibility and effectiveness of the proposed method.
