'''Keywords''': Direct metal deposition, Micro manufacturing, Micro computed tomography

'''Methodology''': Powder injection coaxial with laser beam such as direct metal deposition (DMD) + scanning electron microscopy and micro X-ray computed tomography (μCT).

'''Findings''': Acting on the scanning speed, the surface quality of parts improves.

'''Limitations''':
- increasing the scanning speed inhibits the growth rate in the building direction.

'''Benefits''':
- By using micro direct metal deposition process and specific set of process parameters, feature sizes can be reduced without losing the accuracy, as well as surface finish and density can be improved.

'''Practical implications''': μDMD process was used to produce NiTi parts with predetermined cylindrical holes via tuning of process parameters such as hatch distances and laser spot diameter.

'''Abstract:''' Additive Manufacturing (AM) differs from traditional manufacturing technologies by its ability to handle complex shapes with great design flexibility. These features make the technique suitable to fabricate customized components, particularly answering specific custom needs. Although AM mainly referred to prototyping, nowadays the interest in direct manufacturing of actual parts is growing. This article shows the application of AM within the project 3DP-4H&W (3D Printing for Health & Wealth) which involves engineers and physicians for developing pediatric custom-made medical devices to enhance the fulfilling of the patients specific needs. In the project, two types of devices made of a two-component biocompatible silicone are considered. The first application (dental field) consists in a device for cleft lip and palate. The second one (audiological field) consists in an acoustic prosthesis. The geometries of the devices are based on the anatomy of the patient that is obtained through a 3D body scan process. For both devices, two different approaches were planned, namely direct AM and indirect Rapid Tooling (RT). In particular, direct AM consists in the FDM processing of silicone, while RT consists in molds FDM fabrication followed by silicone casting. This paper presents the results of the RT method that is articulated in different phases: the acquisition of the geometry to be realized, the design of the molds taking into account the casting feasibility (as casting channel, vents, part extraction), the realization of molds produced through AM, molds surface chemical finishing, pouring and curing of the silicone. The fabricated devices were evaluated by the physicians team that confirmed the effectiveness of the proposed procedure in fabricating the desired devices. Moreover, the procedure can be used as a general method to extend the range of applications to any custom-made device for anatomic districts, especially where complex shapes are present (as tracheal or maxillary prostheses).

'''Purpose:''' Show the application of AM within the project 3DP-4H&W (3D Printing for Health & Wealth) which involves engineers and physicians for developing pediatric custom-made medical devices.

'''Methodology:'''
Direct AM: FDM processing of silicone.
Indirect Rapid Tooling (RT): molds FDM fabrication followed by silicone casting.

'''Practical implications:''' developing pediatric custom-made medical devices.

'''Title''': Additive Manufacturing Approaches for Hydroxyapatite‐Reinforced Composites

'''Authors''': Mario Milazzo, Nicola Contessi Negrini, Stefania Scialla, Benedetto Marelli, Silvia Farè, Serena Danti, Markus J. Buehler'''*'''
'''Keywords''': bioinks, bioinspired, composites, hierarchical, hydroxyapatite, materiomics, tissue engineering.

'''Abstract''': Additive manufacturing (AM) techniques have gained interest in the tissue engineering field, thanks to their versatility and unique possibilities of producing constructs with complex macroscopic geometries and defined patterns. Recently, composite materials—namely, heterogeneous biomaterials identified as continuous phase (matrix) and reinforcement (filler)—have been proposed as inks that can be processed by AM to obtain scaffolds with improved biomimetic and bioactive properties. Significant efforts have been dedicated to hydroxyapatite (HA)‐reinforced composites, especially targeting bone tissue engineering, thanks to the chemical similarities of HA with respect to mineral components of native mineralized tissues. Herein, applications of AM techniques to process HA‐reinforced composites and biocomposites for the production of scaffolds with biological matrices, including cellular tissues, are reviewed. The primary outcomes of recent investigations in terms of morphological, structural, and in vitro and in vivo biological properties of the materials are discussed. The approaches based on the nature of the matrices employed to embed the HA reinforcements and produce the tissue substitutes are classified, and a critical discussion is provided on the presented state of the art as well as the future perspectives, to offer a comprehensive picture of the strategies investigated as well as challenges in this emerging field of materiomics.
Purpose: review applications of AM techniques to process HA-reinforced composites and biocomposites for the production of scaffolds with biological matrices, including cellular tissues.

'''Limitations''': An interconnected porosity represents a necessary condition for vascularization, but few studies have evaluated the capability of the constructs to allow the flows of nutrients needed to avoid the necrosis of the tissues and the embodiment in the host site.

'''Benefits''': These composites are used mainly as tools to promote/replace cartilaginous and bone structures due to their chemical similarities to the native tissues.
'''Practical implications''': growth and development of biomatrix.

'''Originality/value''': have found a new material for production of biological scaffolds.

'''Title''': Additive Manufacturing Approaches for Hydroxyapatite‐Reinforced Composites

'''Authors''': Mario Milazzo, Nicola Contessi Negrini, Stefania Scialla, Benedetto Marelli, Silvia Farè, Serena Danti, Markus J. Buehler'''*'''
'''Keywords''': bioinks, bioinspired, composites, hierarchical, hydroxyapatite, materiomics, tissue engineering.

'''Abstract''': Additive manufacturing (AM) techniques have gained interest in the tissue engineering field, thanks to their versatility and unique possibilities of producing constructs with complex macroscopic geometries and defined patterns. Recently, composite materials—namely, heterogeneous biomaterials identified as continuous phase (matrix) and reinforcement (filler)—have been proposed as inks that can be processed by AM to obtain scaffolds with improved biomimetic and bioactive properties. Significant efforts have been dedicated to hydroxyapatite (HA)‐reinforced composites, especially targeting bone tissue engineering, thanks to the chemical similarities of HA with respect to mineral components of native mineralized tissues. Herein, applications of AM techniques to process HA‐reinforced composites and biocomposites for the production of scaffolds with biological matrices, including cellular tissues, are reviewed. The primary outcomes of recent investigations in terms of morphological, structural, and in vitro and in vivo biological properties of the materials are discussed. The approaches based on the nature of the matrices employed to embed the HA reinforcements and produce the tissue substitutes are classified, and a critical discussion is provided on the presented state of the art as well as the future perspectives, to offer a comprehensive picture of the strategies investigated as well as challenges in this emerging field of materiomics.
Purpose: review applications of AM techniques to process HA-reinforced composites and biocomposites for the production of scaffolds with biological matrices, including cellular tissues.

'''Limitations''': An interconnected porosity represents a necessary condition for vascularization, but few studies have evaluated the capability of the constructs to allow the flows of nutrients needed to avoid the necrosis of the tissues and the embodiment in the host site.

'''Benefits''': These composites are used mainly as tools to promote/replace cartilaginous and bone structures due to their chemical similarities to the native tissues.
'''Practical implications''': growth and development of biomatrix.

'''Originality/value''': have found a new material for production of biological scaffolds.
