Additive manufacturing technology is a manufacturing method by accumulating materials layer by layer.
However, in the process of additive manufacturing, the materials are often accompanied by segregation phenomena and non-equilibrium structure and tends to generate residual stress, which seriously affects the mechanical properties of the as-fabricated materials.

The patient is the starting point for the product/clothing development, however, to meet this demand in terms of comfort in its various approaches, it is necessary to consider beyond the needs: limitations, mobility condition, adopted postures, skin injuries complications and implications, the specification of the materials used, as well as its pattern design, structures and technologies.
Materials and Methods For this study, bibliographic research was carried out on the four sub-topics of comfort (ergonomic, psychological-aesthetic, thermophysiological, and sensorial), as well as a bibliographic search of the factors associated with the development of pressure ulcers.
It is the quality of the material to allow, or not, the passage of water vapor through its structure.
It is relevant to emphasize the importance of the interaction of multidisciplinary work in parallel, since the results related to the clinical status of the user, use of materials and technologies, will interfere in the definition of the basic patterns and the final pattern design of each product, considering the needed interaction with these users.

For example, a gripper from the robot system will be matched against an item in the process, taking into account attributes as the weight, dimensions and material properties of the item and attributes such as the valid payload, and grasping methods of the gripper.

The conversions of the thermal conductivity to design values can be done using the following formulas: FT=efTT2-T1 (1) Fm=efψψ2-ψ1 (2) λ2=λ1∙FT∙Fm∙Fa [W·m-1·K-1] (3) where FT, Fm are the conversion factors of temperature, moisture and ageing. fT is the temperature conversion coefficient, fψ is the moisture conversion coefficient volume by volume which values are specific to the materials.

When it comes to detecting physical signals, as body pressure, carbon-based materials are an adequate resource, mainly due to their thermal and mechanical properties, along with their piezoresistive behavior, that is, the ability to change its electrical resistance from a mechanical deformation.
Among these, graphene nanoplatelets (GNPs) have a more affordable price when compared to other carbon-based materials, making it more applicable on an industrial scale [6, 7].
Plasma treatment is a surface treatment of different materials that takes place from the equal discharge of positively and negatively charged particles [11].
Experimental Materials and methods Materials.
It is also possible to observe an increase in roughness in the samples that received the corrosion treatment with NaOH, due to the extraction of low molecular weight materials and the presence of lignin in them [15].

Fig. 4 SEM images of (a) SiO2 and (b) PS-4-400 EDX analysis was carried out to determine the composition of elements in the catalyst materials.
An absolute reduction in mass that occurs above 1000 °C is due to the decomposition of organic residual materials [25].
Thus, these materials are mesoporous.

The study resources were formed from 63 different source types such as journals, conference papers, theses, books as well as standard, a report from Web of Science, Scopus, ProQuest as well as Google Scholar.
They consist of 43 journals, 7 theses, 2 Books chapter, 2 conference paper and 9 websites of VF.
These main strategies further imply: cutting down on the use of energy sources, using the sources again, using recycled materials, protecting natural reservoir, ridding of toxic materials, heading to economic matters and enhancing quality.
The existing gap among agronomic attempts and between various fields of research need to be filled so that industrial, collective thinking is created and the effect of diverse technologies, attempts and materials are strengthened on productivity.

Recently, sandwich construction has become even more attractive to analysis the thermo-mechanical behaviour of advanced composite materials face sheets [1-7].
For both materials, Poisson’s ratio is assumed to be constant ν=0.3 (Fig 9).
