Some Points You Should Know About FDM 3D Printing
Fused Deposition Modeling (FDM) is among the most commonly used and versatile 3D printing technologies. It works by building parts from an extruded plastic filament material through a nozzle, and then laying that plastic down on the build chamber layer per layer. FDM 3D printing can create complex geometries, but there are restrictions in the process that requires support material for any overhanging features. That said, the supports are removed post-process. Read on to learn more about this additive manufacturing method:
Different
materials available
Fused
deposition modeling FDM can print in a wide variety of materials. The
selection typically includes PC and ABS plastics, as well as performance
materials like nylon and Ultem. That makes the process versatile for building a
wide range of prototypes and for low volume production of objects and parts
like enclosures, housings, and functional bits.
Efficient
and cost-effective
As
FDM 3D printing is widely available, it is typically considered cheap, while
being able to efficiently produce high-quality results. The process can also be
scaled, so it should suit most types and sizes of projects. Only the movement
of every gantry is considered the main constraint in the build area’s size. By
lengthening the gantry rails, the build area can be bigger.
How
it differs from other 3D printing technologies
Rapid
prototyping service providers offer a wide range of 3D printing technologies.
Besides fused deposition modeling FDM, they provide SLA 3D printing, which
cures liquid resin with a highly precise laser to create a part one layer at a
time. If your project does not have any fine or intricate details and it won’t
be used for manufacturing or engineering applications that emphasize the
importance of material properties, FDM 3D printing can be a good choice.
Otherwise, you might want to consider SLA 3D printing.
It
struggles to print holes
Does
your project have holes? FDM tends to print them smaller by around two to four
percent. So, you will have to design them slightly larger, or you ask the
manufacturer to drill to size at post-processing. They can also install inserts
for any holes.
