Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Binder jetting (BJ) is a 3D printing technology in which objects are
manufactured from ceramics, metals, polymers, and composites. Binder jetting process
incorporates various types of technologies, such as printing, deposition of powder,
complex combination of the binder with powder, and post-processing of sintered part.
BJ has high productivity with the utilization of a wide variety of powders. In BJ, the
binder is combined with powder of materials that bond together to create an object in a
layer-wise fashion that is generally modeled on CAD. In order to obtain desired
product accuracy, the main challenges are balancing proper process parameters with
manufacturing time, such as characteristics of powders (distribution of particle size,
packing density and flowability of powders, green strength), characteristic of binders,
etc. This paper gives a brief review of technologies, materials, defects and challenges
of the binder jetting additive manufacturing process and their future trends.
