Here, MineLoC is described as a pipeline developed to generate 3D printable models of master templates for Lab-on-a-Chip (LoC) by using a popular multi-player sandbox game “Minecraft”. The user can draw a simple diagram describing the channels and chambers of the Lab-on-a-Chip devices with pre-registered color codes which indicate the height of the generated structure. MineLoC converts the diagram into large chunks of blocks (equal sized cube units composing every object in the game) in the game world. The user and co-workers can simultaneously access the game and edit, modify, or review, which is a feature not generally supported by conventional design software. Once the review is complete, the resultant structure can be exported into a stereolithography (STL) file which can be used in additive manufacturing. Then, the Lab-on-a-Chip device can be fabricated by the standard protocol to produce a Lab-on-a-Chip. The simple polydimethylsiloxane (PDMS) device for the bacterial growth measurement used in the previous research was copied by the proposed method. The error calculation by a 3D model comparison showed an accuracy of 86%. It is anticipated that this work will facilitate more use of 3D printer-based Lab-on-a-Chip fabrication, which greatly lowers the entry barrier in the field of Lab-on-a-Chip research.

“…Overall simulation-based cost comparison of various techniques including material jetting, vat polymerization and FDM has been performed in a previous study. 23 That study, along with a one focusing on FDM and binder jetting techniques, has also found the FDM method to be the most cost-effective approach and the vat polymerization, material jetting and binder jetting to be capable of producing higher quality models. 10,23 Another advantage of techniques such as vat polymerization and material jetting over FDM technique is the ability to produce higher number of models per print session without significantly increasing the print time or cost.…”

Objective The aim of this study was to compare technical and physical features of four three-dimensional printed bone models used for teaching purposes to commercial models. Study Design A canine tibia was imaged using computed tomography and used for model development. Tibial models were printed using Resin, polylactide acid (PLA), acrylonitrile butadiene styrene (ABS) and high-impact polystyrene (HIPS). They were compared with two commercial models (SAWBONES 2117 and 2108). Models were drilled in three locations and then cut transversely. Subjective quality of models, time and cost of production were compared. Results Print time was approximately 3 hours for Resin and 4 hours for each of the PLA, ABS and HIPS models. Unlike the Resin and SAWBONES, the PLA, HIPS and ABS had higher heat generation during both drilling and cutting with mild construct deformation at cut surfaces in ABS and PLA models. Characteristics of real bone during drilling and cutting were best simulated in decreasing order by Resin, PLA, ABS and HIPS followed by SAWBONES 2117 and 2108 models. Material costs were $14.6 (Resin), $0.48 (PLA/ABS), $1.52 (HIPS), $23.50 and $17.50 for SAWBONES 2117 and 2108 per model, respectively. Resin performed best and had the closest subjective tactile properties to real bone. Conclusion The three-dimensional printed tibial bone models provide a cost-effective alternative to commercially available bone models in veterinary medicine as teaching models.

“…Valves can be tested on different internal structures to reduce the overall weight of the valve while maintaining its structural integrity. Additive manufacturing is potentially a motivating force in numerous industries towards advanced manufacturing initiatives [15]. The goal of this evolution is to produce better performing products with reduced costs and efficiency.…”

Experimental and Numerical Investigation of Six-Bar Linkage Application to Bellow Globe Valve for Compact Design

et al. 2018

View full text Add to dashboard Cite

Bellow sealing in valves provides the characteristic of no emission sealing by extending or compressing within the elastic limit to operate the valve. To keep the motion of the bellow within the elastic limit, a long length of bellow is required, which increases the length of the shaft and height of the valve. Increased height restricts valve usage, especially for large sizes, due to the limited platform space. This study presents the application of a six-bar linkage to operating mechanism by replacing the reciprocating shaft in an attempt to reduce the height of the valve. The mechanism produced aims to reduce the input displacement while maintaining the output displacement in order to reduce the required bellow length. Graphical synthesis of the mechanism was carried out using Autodesk Inventor. The designed mechanism was then subjected to analysis using a simulation tool for the position, force, and flow analysis. The prototype valve with the application of the new mechanism was manufactured using additive manufacturing, which was later used for experimental testing. Application of the mechanism to the bellow valve reduced the required input by 75%, which as a result, reduced the height of the valve up to 50%. The force analysis depicted that the force required to operate the mechanism was approximately eight times higher than the conventional design. Flow analysis of the valve showed that the introduction of the new mechanism had no effect on the flow efficiency of the valve and the flow coefficient of valve remained the same. Application of the six-bar linkage to the valve control mechanism made the design of the valve compact when compared to conventional design in terms of height, which makes it more suitable for use in industry.
