“…It is worth mentioning here that 3D stereo-lithographic (SL) is an additive manufacturing method that widely used to produce 3D microfluidic structures. This method can produce good fabrication resolution and acceptable fabrication time, but is too limited by the device speed and space [ 27 , 28 ]. Moreover, good dimensional stability, chemical inertness, and acceptable optical transparency can be produced using this method.…”

The fabrication and testing of spiral microchannels with a trapezoidal cross section for the passive separation of microparticles is reported in this article. In contrast to previously reported fabrication methods, the fabrication of trapezoidal spiral channels in glass substrates using a femtosecond laser is reported for the first time in this paper. Femtosecond laser ablation has been proposed as an accurate and fast prototyping method with the ability to create 3D features such as slanted-base channels. Moreover, the fabrication in borosilicate glass substrates can provide high optical transparency, thermal resistance, dimensional stability, and chemical inertness. Post-processing steps of the laser engraved glass substrate are also detailed in this paper including hydrogen fluoride (HF) dipping, chemical cleaning, surface activation, and thermal bonding. Optical 3D images of the fabricated chips confirmed a good fabrication accuracy and acceptable surface roughness. To evaluate the particle separation function of the microfluidic chip, 5 μm, 10 μm, and 15 μm particles were focused and recovered from the two outlets of the spiral channel. In conclusion, the new chemically inert separation chip can be utilized in biological or chemical processes where different sizes of cells or particles must be separated, i.e., red blood cells, circulating tumor cells, and technical particle suspensions.

“…89 Latest advances in skin 3D scaffolds include the use of novel composite biomaterials such as a gelatine-sulfonated silk composite scaffold, which is used to stimulate neovascularization within the construct, 90 and the applications of innovative technologies in scaffold fabrication such as stereolithographic 3D bioprinting, a layer-by-layer photopolymerization system which provides good material selection, resolution, speed and low surface roughness. 91,92 Another example is the use of mechanical micromilling technology, a precise fabrication of undulated microtopographies of poly(methyl methacrylate) to mimic dermal papillae of skin. 93 These innovative technologies allow to have the possibility to overcome one of the main problems in skin TE which is the deficiency of dermal vascularization, as well as improving the resolution and biomimicry of the scaffolds.…”

Regenerative medicine and tissue engineering (TE) have experienced significant advances in the development of in vitro engineered skin substitutes, either for replacement of lost tissue in skin injuries or for the generation of in vitro human skin models to research. However, currently available skin substitutes present different limitations such as expensive costs, abnormal skin microstructure and engraftment failure. Given these limitations, new technologies, based on advanced therapies and regenerative medicine, have been applied to develop skin substitutes with several pharmaceutical applications that include injectable cell suspensions, cell‐spray devices, sheets or 3Dscaffolds for skin tissue regeneration and others. Clinical practice for skin injuries has evolved to incorporate these innovative applications to facilitate wound healing, improve the barrier function of the skin, prevent infections, manage pain and even to ameliorate long‐term aesthetic results. In this article, we review current commercially available skin substitutes for clinical use, as well as the latest advances in biomedical and pharmaceutical applications used to design advanced therapies and medical products for wound healing and skin regeneration. We highlight the current progress in clinical trials for wound healing as well as the new technologies that are being developed and hold the potential to generate skin substitutes such as 3D bioprinting‐based strategies.

“…The type of 3D printer used depends on the object to be manufactured. For example, SLA provides an interesting compromise between resolution, material selection, speed and low surface roughness [19]. Meanwhile FDM is widely used in the prototyping and direct manufacture of parts using thermoplastic materials [20].…”

Additive manufacturing, also known as 3D printing or digital fabrication technology, is a process of accumulating deposited layers to form solid 3D objects from 3D models in digital fi les. 3D printing technology is a fast-emerging technology. Nowadays, 3D printing technology is successfully applied in shaping the globe and producing most of the products used today, from simple plastics to advanced ceramics and metallics. 3D printing technology can print an object layer by layer, by directly depositing the material using computer software, with only just one click. This paper gives an overview of the Critical Success Factors (CSFs) for 3D printing technology in manufacturing fi rms.The literature found in this paper is mainly from Emerald Insight, Science Direct, Google Scholar and Additive Manufacturing. Briefl y, the list of Critical Success Factors can be divided into nine major factors, which are cost, technology, business and support, management and organisation, materials, quality and accuracy, demand, the environment and lastly, research and development.
