“…The pedestal was printed with a MakerBot ® 3-D printer (Replicator2, New York, NY) using polylactic acid (PLA) thermoplastic filament (MakerBot ® Industries, LLC One MetroTech Center, 21st Fl, Brooklyn, NY 11201 USA). The PLA filament was fed through the printer head, heated to a molten state (200°C)and extruded to harden in 0.2-mm layers on a modeling plate (Bartolomé et al 2017). Our design criteria were: 1) a raised pedestal for support; 2) proper positioning for quick alignment on the device; 3) rapid classification of samples; 4) straightforward but relevant classification categories, and 5) the ability to provide standardization among user groups.…”

Ultra-rapid cooling under the appropriate conditions will produce vitrification, a glass-like state used to cryopreserve small sample volumes, but there are a number of major technical drawbacks impeding application of vitrification to germplasm of aquatic species. These include a lack of suitable devices, and poor reproducibility and comparability among studies due to a lack of standardization. We used 3-dimensional (3-D) printing to produce a viewing pedestal coupled with a classification system to rapidly assess frozen film quality of vitrification loops. Classification time declined with practice from 2.1 ± 0.3 sec to 1.5 ± 0.2 sec (after 200 assessments), and assessments were consistently made in < 2.5 sec. Classifications should be reported with representative images allowing harmonization for quality control. This approach permits rapid classification and can be applied for development of methods including evaluation of vitrification solution components, concentrations of solution and target cells, and configurations and volumes of new devices. Future studies should address the custom fabrication of 3-D printed vitrification devices for use with aquatic species and other applications.

“…28,29 This combination of materials gives ABS excellent toughness, even in cold conditions, such as cryogenic applications. 30 It also provides good rigidity, good thermal stability, and high resistance to chemicals and cracking due to environmental stress. ABS is inexpensive, flexible, lightweight, and easily extruded, which makes it perfect for 3D printing.…”

The use of three-dimensional (3D) printing for the fabrication of microfluidic chips has attracted considerable attention among researchers. This low-cost fabrication method allows for rapid prototyping and the creation of complex structures; however, these devices lack optical transparency, which greatly hinders the characterization and quantification of experiment results. To address this problem, integrating a transparent substrate with a 3D-printed chip is an effective approach. In this study, we present a solvent bonding method of poly(methyl methacrylate) (PMMA) and acrylonitrile butadiene styrene (ABS) thermoplastic materials for the creation of optically detectable 3D-printed microfluidic devices. To achieve an excellent bonding between PMMA and ABS substrates, we used spray coating as a method for the distribution of ethanol solution followed by UV exposure and post-annealing step to improve the bonding strength. We fabricated a microfluidic chip with S-microchannel to characterize the bonding protocol, and other two application-oriented microfluidic chips, including a 3D split-and-recombine-based passive micromixer, and an integrated microchip for the mixing of two streams of liquid prior to the formation of double-emulsion droplets, to evaluate the efficacy of the proposed scheme. As a result, at least eight bars of the bonding strength between PMMA/ABS substrates was achieved, and the ability of producing optically detectable 3D-printed microfluidic devices based on this bonding method was confirmed.

“…In the category of thermoplastics, one of the most used materials is acrylonitrile butadiene styrene (ABS). 1 –3 The ABS is having properties of fast solidification, average strength and cheap in price but have inferior mechanical properties. 4 –8 The studies have reported the use of ABS printed parts on fused deposition modelling (FDM) in medical/surgical applications, 9 –11 anatomies models of animals and humans, and so on.…”

“…Some of the studies outlined the use of nano- or micro-sized particulate for reduce/reuse/recycle (3R’s concept of waste management) prospective by FDM. 2,37 But hitherto very little has been reported on the recycling of thermosetting waste by using it as filler in thermoplastic matrix along with ceramic particulates. The present study is an extension of work reported by Singh et al 37 in which the study was limited to the preparation of innovative feedstock filaments of thermosetting, thermoplastic and ceramics blends.…”

The 3D printing of thermoplastic polymers (both virgin and reinforced with metal/ceramic particles) has been widely explored in recent past with fused deposition modelling (FDM) process. But hitherto very little has been reported on 3D printing of thermoplastics polymers with reinforcement of thermosetting polymers and ceramic particles. This article is an extension of work reported on thermo-mechanical investigations on waste thermosetting polymer bakelite and ceramic (silicon carbide and aluminium oxide) as reinforcement in recycled acrylonitrile butadiene styrene (ABS) thermoplastic matrix for sustainability. The study reports the experimental investigations on mechanical (tensile), morphological, surface hardness and thermal stability analysis of 3D printed functional prototype as tensile specimen (as per ASTM D 638). In the present case study, it has been ascertained that composition/proportion of thermoplastic matrix has a significant role in controlling the mechanical properties, whereas other input process parameters of FDM are insignificant. The results of the study suggest that thermosetting and ceramic-reinforced ABS thermoplastic-based 3D printed parts have mechanical properties at par with unreinforced ABS.
