Direct and Binder 3D Printing techniques

One of the 3D printing techniques is direct (straightforward) 3D printing. Direct 3D printing employs jet techniques, which is used in 2D printing since the 1960s. Just as in a 2D printer, nozzles of a 3D printer move to and from to distribute the liquid. However 3D printer nozzles or the printing side go up- and downward, so lots of layers over the same surface appear. What’s more, 3D printers use no ink, instead they spread waxes and plastic polymers that harden, thus forming newer cross-sections.

The leading factor that influenced 3D printing is rapid prototyping. The earliest effective technology to use inject method in RP was the Model Marker by Solidscape company, 1994. Then other products succeeded each using wax components. Today’s RP commodities employ technologies like multi-jet modeling (MJM). MJM creates wax samples rapidly employing several nozzles at a time.

Binder (or linker) 3D printing makes use of inkjet nozzles to employ a fluid forming new layers. Contrary to direct printing, however, binder printing employs 2 different materials separately that mix together forming new layers: dry powder with dissolved glue or binder. Binder (or linker) 3D printer takes two gaps to make each layer. First gap rolls out attenuated powder covering, the second using nozzles to employ the binder. A platform lowers a bit to let another layer of powder. The whole procedure repeats till the model is ready.

3D printing MIT employs binder method. To let other companies use 3D printing a company is to use some specific mixture of powder and binder stuff.

There are some advantages of a binder 3D printer over direct 3D printing. First, it turns to be faster than direct 3DP for less material is used via nozzles. Second, you can combine a wide range of materials from metals and ceramics to colours.

Fused deposition modeling (FDM) is viewed as additive manufacturing approach being similar to 3DP. However, that’s not the same. Badged by Stratasys, Inc., FDM includes forcing liquefied plastic in packed lines through minuscule nozzles. By FDM one can create things as tiny as part of a millimeter.
