Brass is one of the most used materials for threaded inserts. Here, in this blog, we are explaining the use of brass threaded inserts.

1. Brass Threaded Inserts
for 3D Printing?

2. Threaded inserts are useful because they add long-
lasting and powerful threads into 3D print.
You can insert holes directly to 3D printed parts, but
they wear down very fast.
It is because thermoplastics are used in 3D printing,
and they are soft.
To enhance durability, brass threaded inserts are used.
How are threaded inserts in 3D prints? Here, in this
blog, we are explaining the use of brass threaded
inserts.

4. How do threaded inserts work?
Threaded inserts come with ribs and they have edges on
the outside. They are typically called knurling. The
knurling allows the inserts to hold the plastic and
makes it difficult for them to be twisted or pulled out.
On the inside of the brass inserts there are durable
threads.

5. Methods for installing threaded inserts in 3D
prints
There are several methods that can be used to install
threaded inserts in plastic. But all of them may not be
relevant and useful.
For example, threads that are inserted ultrasonically
are applicable in industrial equipment. Molded threaded
inserts in plastic can’t be used in 3D printing.

6. Heat-setting inserts
Heat-setting involves melting the plastic that surrounds
the insert so that it can be inserted properly. As the
plastic cools, it reflows around the insert and forms a
strong bond along with the knurling.
The only downside of this method is that it might get
misaligned accidently while heat-setting.

7. Ultrasonicinserts
They use high-frequency vibrations to generate friction
and heat.
Press fittinginserts
They can be simply press-fit into 3D prints without
heating. Since the plastic does not melt around knurling
and gets firmed, the bond created here is weaker.
