Enabling True Multi-Material 3D Printing

Introduction to Binder Jet 3D Printing

Binder Jetting is an additive manufacturing process that involves the selective deposition of a binding agent onto a powder bed. This 3D Printing technology is renowned for its ability to produce complex geometries, intricate details, and a wide range of materials. Unlike other 3D printing technologies that rely on melting or sintering materials, Binder Jet 3D Printing technology uses a binding agent to join powder particles, offering unique advantages. The promises of additive manufacturing are limitless: printing entire assemblies and organic shapes without design constraints, no tooling requirements or lead times, and fast, local production options.

How Binder Jetting Works

Binder jetting 3D printing technology is based on two key elements: a powder and a binder. The powder can be a mineral, metal, ceramic, or another material you want to bond in powder form. The binder is a liquid, which acts as an adhesive between powder layers.

Preparation of the Powder Bed

A thin layer of powdered material (metal, sand, ceramics, or composites) is spread across the build platform using a roller or blade.

Deposition of the Binding Agent

An inkjet print head selectively deposits droplets of a liquid binding agent onto the powder bed, following the cross-sectional pattern of the object being printed.

Layer-by-Layer Construction

The process repeats layer by layer. Each new layer of powder is spread over the previous one, and the binding agent is deposited to bond the layers together. After each layer, the printed object is lowered on its build platform by the layer thickness. A new layer of powder is deposited, and the process repeats. Unbound powder remains in position surrounding the printed object.

Post-Processing

Once the entire object is printed, excess powder is removed. The printed part often undergoes additional processes such as curing, infiltration with a secondary material, or sintering to enhance strength and other properties.

Any print starts with a 3D model of the object or product, which can be included in a print job. The 3D Printing software, designed specifically for optimizing binder jet 3D printing enhances the user experience. Through its intuitive interface, the the 3D Printer design software provides full control over variables like layer height and print speed. Printed objects are self-supported and don’t require additional structures.
