extensive work on phenolic resin binders for some time. Its new binder, introduced at this year’s Eu- romold offers a number of advantages for many 3D printing applications, as process engineer Dr. Florian Mögele can attest: “With this binder, we are able to achieve an incredible level of resolution and precision in 3D printing. At the same time, we have also made significant improvements in terms of stability and sand recycling. And, phenolic resin binders are ideally suited for processing ceramic and other materials.” 3D printed, complicated phenolic-direct-binder


(PDB) sand molds surpass even the highest expecta- tions. The PDB method, with its impressive accuracy and increased strength, is setting new trends, especially for complex molds with undercuts, elaborate details and very small radii. Te phenolic resin used is nontoxic and allows for 100% recycling of non-printed particle material. In contrast to


Voxeljet公司的研发实验室已做了大量的酚醛树脂 研究工作。公司在今年的Euromold展会上推出了新 型粘结剂，为很多3D打印应用带来了优势，正如工 艺工程师Florian Mögele博士所说：“有了这种粘结 剂，我们就能够在3D打印中达到难以置信的分辨率和 精度。同时，我们在稳定性和旧砂回收利用方面也已 经获得了很大的提升。此外，酚醛树脂粘结剂适合用 于陶瓷和其它材料。”


3D打印结构复杂的酚醛树脂粘结剂(PDB)砂型，甚 至超出了最高预期。PDB工艺具有表现突出的精度、 强度进一步增强，确立了新的发展趋势，尤其适用于 有侧面凹陷、表面质量高和半径非常小的复杂砂型。 使用的酚醛树脂是无毒的，可使未打印的颗粒材 料100%循环利用。与传统的粘结剂相比，PDB工艺
