Advantages and disadvantages of FDM technology:

Advantages Disadvantages

+ a very economical method of production from - the need to avoid large flat surfaces and
thermoplastic elements, the additional thin elements due to susceptibility to
advantage of which is the fast pace of deformation,
construction and low material losses - although the elements are characterized by
+ possibility of making prototypes from a wide high strength in the Z axis, they are fragile in
range of plastics in various colors the XY axis, which means that this
+ very economical construction of elements technology is rarely used for mechanically
made of thermoplastics heavily loaded components,
+ short time of making a model, both a - lower dimensional accuracy for elements
functional prototype and creating a conceptual with complex and geometrically complex
model shapes compared to other machining
+ possibility of printing the model in office methods
conditions - in order to remove the visible lines of
+ exploitation of high dimensional accuracy + - printing of subsequent layers of material,
0.15 to + -0.3mm additional processing of the model is
necessary

Classes of FDM 3D printers

Currently, the market is dominated by FDM printers, which meant that this type has become
synonymous with 3D printing, despite the fact that there are many more types of incremental
methods on the market.

The number of FDM printers on the market is currently countless, which causes considerable
problems for an ordinary user with the choice of a model. Printers can be divided into classes that we
can buy from 100 Euro to even several hundred thousand Euro. The simplest division is into
categories:

• amateur

• desktop

• professional

• production

Each is suitable for a different element, is designated for a different thing, has a different
functionality and potentiality.
