Overview: How FDM 3D Printing Works?

The Basics of FDM 3D Printing:
There are several different methods of 3D Printing, but the most widely used is a process known as Fused Deposition Modeling (FDM). FDM printers use a thermoplastic filament heated to its melting point and then extruded, layer by layer, to create a three-dimensional object.

Why Choose FDM 3D Printing With Unionfab

Features of FDM 3D Printing

Material Selection

FDM printers supports a wide range of engineering thermoplastics and even some reinforced compound materials like PA-CF.

Accuracy

We use the most advanced industrial FDM 3D printers with tolerances of ± 0.004” or ± 0.002” per inch, whichever is greater.

Geometry

With dissolvable supports (industrial-level only), complex geometries and interlocking structures can be produced with ease.

Surface Quality

Extruding material layer-by-layer, the surface has layer lines and fine details cannot be realized.

Layer Adhesion

The unit cost and lead time will not be reduced as much as casted or molded parts.

Strength & Durability

High-performance plastics like PA/PC/ULTEM are ideal for applications that require resistance of certain aspects.

Turnaround

FDM parts do not require tooling which reduces the manufacturing lead time from weeks to days, allowing for faster innovation and speed to market.

End Production

FDM is capable of producing end-use parts on-demand to boost your marketing by customization.

Scale Effect

The unit cost and lead time will not be reduced as much as casted or molded parts.

Available Finishes

Default:

FDM parts are built with support material that is removed during post-processing. The part surfaces are left with fine layer lines.

Other:

・Painting
・Vapor Smoothing
・Want to custom the finish you need? Request in the quoting tool, we’ll evaluate your finishes on a case-by-case basis.

FDM 3D Printing Applications

Prototypes

FDM is ideal for producing form / fit and functional prototypes for testing in standard materials like PLA / ABS.

CEnd Parts

The heat tolerance and great mechanical properties of industrial FDM materials let end parts like jigs, fixtures, brackets be produced directly.

Customized Products

FDM can be applied to make small batched products with varied requirments, ideal for small businesses that wishes to test the market’s reaction to thier newly developed products.
