Originally introduced in 1980, additive manufacturing, more commonly known today as 3D printing, is a cost-effective method for creating plastic parts and prototypes. Advances in technology now allows for more sophisticated printers, making it easy for manufacturers to print three-dimensional parts using metal materials. Additionally, additive manufacturing also includes ceramics and gives injection molders an alternative process for building parts.

The ability to print a variety of materials with a computer-aided design (CAD) file makes 3D printing increasingly effective for both prototype and certain production environments. Although start-up costs remain high, additive manufacturing’s convenience and volume production potential continues to make the 3D printing industry appealing to manufacturers. Notable major manufacturers like GE, Honeywell, IBM, amongst others already embrace 3D printing for parts production and prototype applications.

A variety of industries use 3D printing to create commercial metal parts. Manufacturers print these parts using:

• Aluminum

• Stainless steel

• Brass

• Copper

• Bronze

• Sterling silver

• Gold

• Platinum

• Titanium

• Hybrid ceramic compounds

Depending on the environment or application, manufacturers use common processes, like sintering, debinding, fusing, curing, heat treatment and more, to achieve results for finished parts. A high-temperature industrial furnace is then used to apply these treatments to 3D-printed parts or prototypes. In addition to a controlled heat environment, a versatile vacuum furnace supports a variety of atmospheres, including hydrogen, argon, or other inert gases, to facilitate metal processing.

Integral for additive manufacturing, sintering furnaces and dry ovens make 3D metal printing parts and prototypes accessible and cost-effective. Industrial vacuum furnaces deliver precise temperature control and uniform heating consistency. Additionally, depending on the materials used, a high-temperature sintering furnace makes it easy to control environments and atmospheres. Consider a Sentro Tech sintering furnace for your 3D metal printing needs.

Use Sentro Tech high-temperature furnaces for de-binding and sintering under controlled atmosphere. The de-binding process applies heat to parts under controlled partial vacuum argon atmosphere to remove binder. De-binding partial pressure is typically between 3-30 Torr. After the de-binding process, increase furnace temperature to metal sintering temperature. This forms dense metal parts either under vacuum, partial vacuum, or controlled positive atmosphere. Our high-temperature vacuum sintering furnace features typical vacuum 10-4 to 10-5 torr. And the partial vacuum argon atmosphere offers typical vacuum from 3-300 torr. Positive atmosphere sintering features typical pressure from 760 to 1100 torr.

Sentro Tech offers a wide range of high temperature furnaces, dry ovens, and heating equipment. Choose from standard models or custom-built models to best suit your application or production needs. Our vacuum furnaces provide reliable temperature uniformity and control. Additionally, with a wide range of heating parts, accessories, alumina tubes, and heating elements, we deliver the resources needed to ensure an always successful, efficient, and quality-controlled manufacturing process.
