什么是砂型3D打印�?/h2>

砂型3D打印是一种比较新的技术，简单来说，就是像搭积木一样，用特殊的材料一层一层地 “堆�?出铸造用的砂型�?/p>

以前传统的做砂型方法，可能需要先做模具，再用模具去造型，过程比较复杂，而且如果要做一些形状很奇怪、很复杂的砂型，就会特别困难，成本也高。但砂型 3D 打印就不一样了，它是通过电脑里的三维模型来工作的。你把设计好的铸件三维模型数据输入到 3D 打印机里，打印机就会根据模型的形状和结构，把特殊的沙子或者类似沙子的材料，按照一层一层的方式精准地铺放和粘结起来，就像用无数个很薄的 “沙片�?逐渐搭建成一个完整的砂型。这样，不管是多么复杂的形状，只要能在电脑里设计出来，它都能打印出来，而且速度还挺快，也不需要像传统方法那样制作复杂的模具，能节省很多时间和成本呢�?/p>

喷射粘结�?/strong>：喷头按照计算机模型（CAD数据）精确喷射粘结剂，使特定区域的砂粒粘结在一起�?/li>

重复堆积：平台下降，再次铺砂并喷射粘结剂，逐层固化成型，直至整个砂型打印完成�?/li>

long production lead time：传统砂型铸造需经历设计模具、制造模具、调试模具等冗长流程，大型模具制造周期常超数月�?D 打印砂型无需模具制作，直接按数字模型打印，设计修改也只需在电脑上操作模型，重新打印即可，能大幅缩短生产周期。如研发新款汽车发动机缸体时，传统铸造模具报废重制至少两周，3D 打印砂型当天就能完成新模型打印，次日即可投入铸造�?/li>

Difficulty in cost control：传统铸造模具制造材料浪费严重，复杂模具材料利用率不�?30%，且人工成本高�?D 打印砂型按需打印，精准用砂，材料利用率超 90%，减少浪费。打印过程自动化程度高，可降低人力成本。以小型铸造厂为例，年产能 5000 件小型管件铸件，引入 3D 打印砂型后，材料成本年降 15 万元，人工成本削�?20 万元�?/li>

铸件精度�?/strong>：传统砂型因模具磨损、分型面贴合误差等，铸件尺寸偏差常超 ±1mm，后续机加工余量多、材料浪费大，且易出现局部疏松、夹砂等缺陷，导致铸件力学性能不均�?D 打印砂型由数字化模型精准驱动，砂型尺寸精度可�?±0.5mm 以内，能实现均匀紧实，避免砂粒松散不均，同时优化凝固过程，大幅减少缩孔、缩松，保障铸件内部质量稳定可靠�?/li>

环保压力�?/strong>：传统铸造的模具制造产生大量废金属、废塑料，砂型处理后废砂堆积如山�?D 打印砂型生产中，未使用的砂可回收再利用，废弃物极少，且打印过程无需大量化学粘结剂，减少有害气体挥发，改善车间环境。据统计，采�?3D 打印砂型后，铸造车间废弃物排放降低�?80%，粉尘、有害气体浓度达环保标准�?/li>

产品复杂�?/strong>：若铸造厂经常生产复杂形状、有精细结构或内部通道的铸件，如航空发动机叶片、汽车缸体等，传统工艺难以满足要求，砂型3D打印机能发挥优势�?/li>

生产规模与批�?/strong>：对于小批量、多品种的铸件生产，砂型 3D 打印机可灵活快速切换产品，无需制作模具，能降低成本和周期。但大规模、单一品种的铸件生产，传统工艺可能更具成本效益�?/li>

交货期要�?/strong>：若客户对交货期要求严格，砂�?3D 打印机可缩短生产周期，快速响应订单�?/li>

The boxless 3D printer is so named because it eliminates the use of a traditional box in the sand 3D printing process, significantly differentiating it from conventional sand 3D printers. Here's more about it from a variety of perspectives:

The role and limitations of traditional sandboxesSandboxes are an indispensable part of the traditional sand casting process and some traditional sand 3D printing techniques. It is used to hold the sand, provide molding space for the sand model, ensure that the sand maintains a specific shape during the molding process, and ensure the integrity of the sand model during transportation and box closing. However, the fixed size of the sand box limits the size of the sand mold that can be produced, and the production and maintenance costs are high. For the complex structure of the sand mold, the sand box is difficult to design and manufacture, and it may also affect the heat dissipation and air permeability of the sand mold, which may affect the quality of the castings.

How sandless box 3D printers work: The sandbox-less 3D printer adopts sandbox-less flexible area molding technology, in which abrasive and binder are stacked and molded layer by layer by the nozzle directly on the worktable. The equipment has a precise sand spreading system, which can evenly spread the sand material in the printing area, and the nozzle accurately sprays the binder according to the model cross-section information, so that the sand particles are bonded to form the sand shape layer by layer. In this process, there is no need for a sand box to provide molding space and constraints, which greatly improves printing flexibility and freedom.

Basis of namingThe naming of the 3D printer directly reflects its core technical feature, which is that it is free from the constraints of the traditional sand box, creating a new mode of sand 3D printing. This naming scheme is simple and clear, highlighting the essential difference with the traditional sand 3D printing equipment, and emphasizing its unique advantage of realizing high-precision and high-efficiency manufacturing of sand patterns without the assistance of a sand box during the printing process.
