3Diligent's Binder Jetting Service is a cost effective option for full color models (Color Jet Printing) and for functional metal parts (Binder Jetting with Metal Infiltration). If you've got a project that calls for Binder Jetting, submit an RFQ through our secure portal. Have more questions about the process or our service? Read on or email us with a description of your project needs and we'll be in touch to discuss further.
Binder jetting involves selectively ejecting a binding agent onto a powder bed. After a layer is finished, the powder bed will descend the height of one layer and a new layer of fresh powder will be evenly spread across the part. After the shape of the part is printed, the part (now in the green state) will undergo some sort of post processing to make it stronger, commonly baking in a kiln. As a powder bed based process, it is capable of printing downward facing surfaces with relative ease.
With Binder Jetting, an adhesive is selectively applied to a powder (typically gypsum or stainless steel, but materials like ceramics are being explored in academic settings) to form each layer. After the part is printed and depowdered, it is exposed to a permanent binder to make the part stronger. Certain binder jetting printers - Color Jet Printers - are capable of applying colored adhesive, which provides the opportunity to print in full color. This makes color jetting parts ideal for visual models and color nonfunctional parts with complex geometries.
