一般咨询


How does ExOne® binder jet process work?

ExOne 根据在麻省理工学院开发的专利 3DP 流程,采用耐用的工业级材料自下而上构建功能性 3D 物体,一次构建一层。如需了解有关该流程的信息,请参阅“技术概述”页。

3D 打印组件的耐用性如何?

这取决于所使用的材料系统。对于不锈钢和青铜金属部件,极限抗拉强度介于 60 和 100 ksi 之间,硬度水平为 20-30 HRc。

表面质量如何?

表面质量取决于您选择的材料。每种材料的天然表面质量各不相同。各种修整选项也是如此。对于金属打印,我们提供了各种镀层选择。如需了解更多细节,请查看我们的“材料”页。

你们可以达到哪种精度公差?

ExOne® sand printers can achieve printing tolerances of +/- 0.3 mm (0.012 in). ExOne® metal printers can achieve accuracies of +/- 0.13 mm (0.005 in) in components under 75 x 75 x 75 mm (3 x 3 x 3 in); +/- 0.25 mm (0.010 in) in components up to 250 x 250 x 250 mm (10 x 10 x 10 in); and +/- 1.3 mm (0.050 in) for the largest components up to 780 x 400 x 400 mm (30.7 x 15.75 x 15.75 in).

能否同时打印多个部件?

是的。软件允许同时处理打印箱中可容纳的部件数量,各个部件可以各不相同或完全定制。这能最大程度地利用时间并减少浪费。打印构建箱中多个部件的时间与打印一个部件的时间相同。

有其他可用材料吗?

是的。目前正在开发多个金属选项。请向 ExOne 咨询您的具体需求。

能否全球发货?

是的。ExOne 在三大洲设有工厂,可全球发货。

如何获得报价?

能否从您的工厂订货?

是的。Each of our global facilities has the resources to take your order and forward it to the appropriate location for processing.

Metal Parts on Demand


How do I know I need a printed metal part?

ExOne offers on-demand 3D printing for metal parts as well as sand castings and specialty materials. The most common application of our 3D metal printing is the manufacture of customized, complex parts. We can handle a variety of throughput requests from rapid product development to serial production, and have finishing options that will help you efficiently bring your part from conception to market. Our customers also leverage our 3D metal printing service to create prototypes or conceptual models.

Will I require finishing services when 3D printing metal parts?

ExOne® metal Parts on Demand are “near-net,” meaning some finishing may be desired or required. We offer a full array of finishing services that can be added to our on-demand metal 3D printing packages. 如需了解详细信息,请与我们联系。

是否需要数字文件创建方面的帮助?

ExOne 接受各种数字建模文件类型,首选方式是 STL,也可以通过我们的“请求报价”表单轻松上传文件。If you need assistance creating a file, please inquire about our design services for 3D metal printing.

When will my parts be available?

Standard lead time for 3D printing metal parts is 10 working days, but will depend on the volume and complexity of the job. Rush services are available, so reach out to get a customized quote for 3D metal print service.

Can you accommodate the volume of my order?

Iterative or individually customized parts can be managed in a single print run, but 3D metal printing services are also available for serial production. Whether manufacturing lots of 1 or 1,000, the binder jetting process is the most economical choice for 3D printing metal Parts on Demand.

Sand Parts on Demand


How do I know if 3D printed sand molds or cores will meet my needs?

ExOne 使用金属或砂芯特种打印系统来提供按需定制部件。Our services can be leveraged to create 3D printed cores, complex prototype molds, or production-scale casting molds. Request a quote to get in touch with a consultant who can determine the best approach based on your requirements.

Is assistance available to create a digital file?

ExOne 接受各种数字建模文件类型,首选方式是 STL,也可以通过我们的“请求报价”表单轻松上传文件。If you need assistance creating a file that is suitable for 3D printed molds, please inquire about our design services.

When will my parts be available?

Standard lead time for 3D printed sand molds and cores is 5-7 working days, but may depend on the complexity of the casting mold or volume of the order. Rush services are available, so reach out to get a custom quote for 3D printing.

Can you accommodate the volume of my order?

The binder jetting process for 3D printing sand casting molds can help you save on production costs whether you need a lot of 1 or 1,000. At ExOne, we’re equipped to help you quickly develop a casting mold for a one-off prototype and its ensuing iterations, as well as produce 3D printed molds and cores at scale. Request a quote to obtain customized cost and timing scope for your order.

Washout Tooling on Demand


What is Washout Tooling commonly used for?

3D printed soluble support materials are designed to create hollow tooling and composite parts with trapped geometries. You can order parts on demand developed with washout tooling for aircraft ducting, pressure tanks, mandrels and more.

Can you help design a digital file?

ExOne 接受各种数字建模文件类型,首选方式是 STL,也可以通过我们的“请求报价”表单轻松上传文件。如果您需要获取关于创建适合 3D 打印的文件方面的帮助,请咨询我们的设计服务。

What is the typical coating applied to seal the core from resin infiltration?

Teflon® tape wrap or soluble spray-on coating. We can apply whatever coat you need to prepare the cores for finishing in your facility.

What composite materials are compatible?

Currently, ExOne only offers printed and coated cores. Composite layup, curing and washout is completed by our customers using filament winding or application of prepreg woven fabric. Common layup materials that can be applied to our cores are: carbon fiber, fiberglass, aramid fiber or ceramic matrix composites (CMC).

What is the maximum cure temperature for composite part manufacturing?

350°F (177°C)

Are ExOne 3D printed cores autoclave approved?

是的。The core can withstand a maximum autoclave pressure of 85 psi during composite part production.

What do you use to washout the core after the composite part is produced?

Our cores are made with water-soluble support material and are able to be removed with room temperature tap water.

Are there any chemicals or toxins present during washout?

No.

When will I receive my 3D printed tooling?

Standard lead time for washout tooling is 7-10 working days to account for printing, curing and coating the cores. Additional production to apply the composite layup, cure the tooling and washout the core will be required after you receive the parts. 可提供加急服务。

Can you accommodate the volume of my order?

The binder jetting process is the most economical choice for 3D printing hollow objects. 无论是包含 1 个还是 1000 个部件的批次,打印效率都相同。Additionally, iterative or individually customized washout tooling can be printed in a single print run.
