“…For example, in the field of biomedicine, there is a strong interest in the development of engineered lattice structures capable of mimicking the mechanical behavior of bones and providing strong bonding with surrounding tissues via the bone tissue ingrowth [5,6]. Moreover, the high surface/volume ratio of lattice structures makes them especially appropriate for high-efficiency heat exchangers [7] and catalyzers [8]. The power requirements for pumping fluids and gases through the lattices are reduced as compared to traditional foams due to their periodicity and, therefore, their higher permeability.…”

Abstract:The fabrication of engineered lattice structures has recently gained momentum due to the development of novel additive manufacturing techniques. Interest in lattice structures resides not only in the possibility of obtaining efficient lightweight materials, but also in the functionality of pre-designed architectured structures for specific applications, such as biomimetic implants, chemical catalyzers, and heat transfer devices. The mechanical behaviour of lattice structures depends not only the composition of the base material, but also on the type and size of the unit cells, as well as on the material microstructure resulting from a specific fabrication procedure. The present work focuses on the static and fatigue behavior of diamond cell lattice structures fabricated from an AlSiMg alloy by laser powder bed fusion technology. In particular, the specimens were fabricated with three different orientations of lattice cells-[001], [011], [111]-and subjected to static tensile testing and force-controlled pull-pull fatigue testing up to 1 × 10 7 cycles. In parallel, the mechanical behavior of fully dense plain and notched tensile specimens was also studied and compared to that of their lattice counterparts. Results showed a significant effect of the cell orientation on the fatigue lives: specimens oriented at [001] were~30% more fatigue-resistant than specimens oriented at [011] and [111].

Additive Manufacturing Technologies: 3D Printing in Organic Synthesis

2018

View full text Add to dashboard Cite

The manufacturing of a three‐dimensional product from a computer‐driven digital model (3D printing) has found extensive applications in several fields. Additive manufacturing technologies offer the possibility to fabricate ad hoc tailored products on demand, at affordable prices, and have been employed to make customized and complex items for actual sale. However, despite the great progress and the countless opportunities offered by the 3D printing technology, surprisingly a relatively limited number of applications have been documented in organic chemistry. This Minireview will focus specifically on the exploitation of additive manufacturing technologies in the synthesis of organic compounds, and, in particular, on the use of 3D‐printed catalysts and 3D printed reactors, and on the fabrication and use of 3D printed flow reactors.

“…There have been sporadic reports on the applications of inkjet printing in catalysis. 37,41 Liu et al 37 reviewed some applications of inkjet printing for photo-and electro-catalysts as a family of functional metal oxides. Here, there will be more focus on the synthesis of catalyst materials by inkjet printing for chemical and photochemical reactions.…”
