(Powder 3D Printing Technology Goes To Economy And Efficiency)

Selective laser melting powder metal 3D printing technology (LPBF) has been
developed over the past two decades and has become a potential mass production
solution.

Regarding the cost of additive manufacturing technology, according to the
statistics of the European Machine Tool Association, the current value of metal
additive manufacturing can be divided into four components, the direct
construction cost accounts for 40%, the powder material cost accounts for 27%,
and the post-processing cost accounts for 25%. %, Labor costs accounted for
8%.

It can be said that for 3D printing to achieve larger-scale
industrialization, the prices of equipment and materials need to be further
reduced to a more reasonable level. As far as the development trend of the
machine is concerned, modularization is the development trend of selective laser
melting powder bed metal 3D printing equipment. How does the modularization
option establish a corresponding productive relationship with the cost
calculation?However, researchers at the Aachen University of Technology digital
additive manufacturing DAP have recently developed an innovative method for LPBF
modular machining simulation calculations.

A combination of economy and flexibility

In industrialized industrial applications, economy and high efficiency are
some of the most critical development goals. Therefore, it is the trend for
selected laser melting powder bed metal 3D printing technology LPBF equipment
suppliers to provide modular and scalable machine designs and auxiliary
systems.

Users can individually configure the equipment they need according to their
needs. 3D Scientific Valley finds that this brings two aspects of savings from
an intuitive level. On the one hand, it saves equipment manufacturers' efforts
to develop specialized equipment, and on the other hand, it brings economic and
efficient development channels through a modular combination.

But in what ways do these modules have a positive impact on the efficiency of
the process chain? Considering cost efficiency, which modules are best suited
for a given user needs? Current costing tools cannot reliably answer these
questions, especially when it comes to modular systems or mixed batches, and
cost-effectiveness calculations can vary as much as 30%.

Therefore, researchers at the DAP of the Aachen University of Technology have
recently developed an innovative method for the cost calculation of selective
laser melting powder bed metal 3D printing LPBF technology: the virtual module
simulator method.

The virtual module simulator approach allows both system suppliers and system
operators to make positive statements about economic efficiency and the degree
of system modularity (for the production of the best combination product).

According to the market observation of 3D Science Valley, this method has
been integrated into the entire LPBF digital process chain. Process control is
implemented by individual module instances in a service-oriented architecture
(SOA), which can be polymorphically implemented to benchmark different module
behaviors. Besides, you can parameterize the module by using a parameter
set.

The build time calculated by the simulator can be verified layer by layer
with log timestamps of nine actual build jobs performed on a dual laser LPBF
machine. The average absolute percentage error (MAPE) of this model reaches
0.28%, which is a significant improvement over the regression model with 8.2%
MAPE3 in general.

The layer-by-layer analysis shows that the average deviation is less than
0.2%, and the standard deviation is less than 1% so that the construction time
can be predicted almost independently of the geometry. In addition to the
benefits of a positive cost-benefit statement and a systematic modular
benchmarking approach, nearly accurate build time predictions can optimize
production planning and machine utilization.
