“…As AM technology moves forward evolving towards multiple materials, like lattice structures, new formats are needed. Reference [31] tries to fill the gap for fiber-reinforced composites made by AM. The main idea is that all the areas with constant structure and variable size are modelled automatically and the file format is specialized for internal multi-material micro-structure.…”

“…Thanks to this technique, it is possible to place material at the voxel level (µm) to create complex shapes. Reference [31] relates each voxel to a powder particle or laser beam diameter of the described AM process: the developed file format drives the laser source in order to solidify the material voxel by voxel for better detail manufacturing. Reference [16] uses voxels to simulate the filament deposition process in a 3D voxelized volume, by activating in a binary way the corresponding element where new material is added (i.e.…”

Additive manufacturing (AM) is becoming an important alternative to traditional processes. AM technology shows several advantages in literature, and its use increases in aerospace, automotive and biomedicine. Time reduction in design-to-manufacturing cycle, customization, capability to generate complex shapes in one piece and ability to imitate low-weight bio-inspired shapes are the strength of designs based on AM. Due to its potentials, major progresses were done in AM, thanks to technology evolution and increased computational power. With regard to AM, voxelization can be defined as part’s discretization in hexahedral elements, as done with pixels in 2D image. Voxels are used to speed-up geometry and algebraic manipulation thanks to their inherent advantages. This paper analyses advantages and criticalities of AM and voxel manipulation through a systematic literature review methodology. The analyses are based upon the filtering of a huge amount of publications available in literature up to obtaining the most significant 25 studies published in the last 5 years. The study’s main result is the technology gap’s identification, i.e. where AM and voxelization still need improvements, thus providing the reader with suggestions about possible further studies. Computer elaboration power and voxel discretization algorithms are suggested being key issues in AM’s further development.
