As it happens in most industrial processes, feedstock’s particles size is very important in reuse processes of brick waste and it is directly related with formed materials’ behavior.
Materials and Methods In the presented study, it was used brick waste from construction industry.
The mechanical properties of ceramic materials are quite affected by the properties of crystalline phases present and how they are oriented in it.

Introduction Additive manufacturing (AM) technologies create three-dimensional (3D) parts layer-by-layer of materials in a pattern guided by a digital model.
With the demand for complex-shaped parts increasing, Laser Powder Bed Fusion (L-PBF), the leading AM technology for metallic materials, opens new possibilities.
The RAM technology can be used to make a variety of materials, but it is particularly well suited for reactively synthesizing ceramic reinforcements in metal matrix composites.
However, the two materials are characterized by different fatigue performance with L-PBF Al2024-RAM2 showing longer lives for a given applied stress than L-PBF AlSi10Mg.
· Al2024-RAM2 alloy contains strengthening particles on the base of Cu and Mn, which are typical for conventionally produced materials, too.

It shows that the materials are accumulated in the tooth cavity after being pre-forged, setting the basis of locally loading for the final gear form.
As the deformation continues, the lower part of the materials has begun to fill for tooth cavity.
When the tooth profile is going to be filled up, forming resistance increases, the materials start to go upward to fill the upper boss.

The tensile properties of electrospun 3-D meta-aramid nanofiber mat, approximately 0.2–0.4mm (Height) by 20mm (Width) by 50mm (Length), were characterized using a Kawabata Evaluation System (KES-G1, Kato Tech Co., Japan) according to routine mechanical testing methods for fabric materials [6].
On the other hand, heating under certain temperature would also increase some properties of materials such as their thermal property, which may lead to the enhancement of crystalline structure during annealing treatment.
