Adhesive for Granular 3-D Printing Application
3-D
printing, also known as additive manufacturing, describes a variety of
fabrication techniques that employ specialized hardware to build up functional
3-dimensional components layer-by-layer. When compared to traditional
manufacturing methods, 3-D printing provides advantages in lower tooling and
raw material costs; limits the production of waste; and requires minimal setup
for the fabrication of very complex parts.
A
number of different 3-D printing processes are currently available. Popular
among them are so-called granular methods, in which a variety of techniques may
be used to selectively fuse small particles of plastic, metal, ceramic, or
glass powders, layer-by-layer, into shapes determined by CAD data. Compared
with other 3-D printing techniques, granular systems use construction materials
that are low in cost and easy to obtain. Additionally, because unfused powder
surrounds and supports the part as it is being built, granular systems are capable
of producing complex finished parts with less difficulty than other 3-D
printing methods.
Granular
3-D printing encompasses several subcategories, each of which is distinguished
by the materials and methods used to produce the finished part. Selective sintering
techniques use either lasers (SLS) or heat (SHS) to fuse thermoplastic
particles together; electron beam melting (EBM) works similarly, but uses metal
powder; and inkjet head 3-D printing uses a chemical agent to bind the
particles together.

Need
Granular
methods are unique among 3-D printing techniques in requiring the help of an
adhesive to form the finished part. Upon completion, finished parts are
typically dipped into an adhesive bath that both coats and impregnates, adding
strength and durability. This adhesive is referred to as aninfiltrant, and is
required to cure quickly over large surfaces with minimal odor or
discoloration.

Solution
Cyberbond’s
3-D printing customers have realized great success using our Apollo 5005
cyanoacrylate as an infiltrant for their parts. 5005’s customized viscosity
allows quick curing without the side effects of a more aggressive
cyanoacrylate; its ethoxyethyl base limits odor and blooming, while allowing
for larger bath volume and subsequent infiltration of larger parts.
