Applications and prospects of machine learning for aerosol jet printing: A review

Aerosol Jet Printing (AJP) is an additive manufacturing process that deposits ink-like materials suspended as an aerosol mist. AJP creates three-dimensional (3D) functional structures onto flat or conformal surfaces in complex shapes without the aid of additional tooling, enabling the manufacturing of extremely fine electrical interconnects with freeform structures. Due to the novelty and complexity of AJP, physical understanding is rather limited, hindering physics-based process modeling and analysis. Fortunately, the data resources from AJP applications, e.g., 3D Computer-Aided-Design data, Standard Triangle Language files, in-situ images of part, and nozzle motion records, provide an unparalleled opportunity for developing data-driven, Machine Learning (ML) methods to characterize AJP processes, support process control, and facilitate product improvement. To thoroughly identify the newfound opportunities, this study reviews state-of-the-art ML methods used in AJP applications, investigates open issues in AJP, and outlooks future development of ML-based research topics for AJP. It sheds light on how to maximize the value of ML on AJP data to develop scalable, generalizable decision-making methods. More future works along the direction will be motivated.

Ellagic acid as stabilizer in the thermo-oxidative degradation of thermoplastic polyurethane

Ellagic acid (EA) is a plant polyphenol with strong antioxidant properties. The stabilizing effect of EA on the thermo-oxidative degradation of the commercial thermoplastic poly(ester-ether urethane) (TPU) was studied for the first time and compared with effect of kraft lignin (KL), butylated hydroxytoluene (BHT) and pentaerythritol tetrakis (Irganox 1010). TPUs doped with antioxidants (ca. 20,000 ppm), were analysed for their oxidation induction time (OIT) at 200 °C and the oxidation onset temperature (OOT). The extent of TPU degradation with and without addition of antioxidants was studied by head space-gas chromatography-mass spectrometry (HS-GC-MS) at 200 °C under aerobic atmosphere. The highest stabilizing effect of EA was attributed primarily to its stronger antioxidant capacity when compared to KL and synthetic polyphenolic antioxidants (BHT and Irganox), which was corroborated by antiradical power studies with 2,2-diphenyl-1-picrylhydrazyl (DPPH). The analysis of the volatile products released under thermo-oxidative degradation showed the suppressive effect of EA on the thermally induced depolymerization of TPU occurring via homolysis. Furthermore, it has also been proposed that EA affects TPU degradation with the cleavage of urethane bonds in carbamates due to eventual coordination with the intermediate cyclic intramolecular transition complex involved in thermally induced depolymerization. Further studies in this area can prompt the performance improvements of TPU products, allowing them to be used in a wider range of durable goods applications.

Idea crowdsourcing platforms for new product development: A study of idea quality and the number of submitted ideas

Organizational innovation communities for new product development (NPD) have become an integral part of organizations' strategy to find innovative ideas for new products with the help of their consumers. The success of these communities largely depends on users' idea submission and idea quality. While more ideas will increase the chance of finding novel ideas, more low-quality ideas will increase the costs of finding novel ideas. Although the idea crowdsourcing literature has grown significantly, it is relatively new and focused on idea crowdsourcing platforms for product improvement ideas where individuals submit ideas to fix software bugs or to request new features. By examining idea quality (measured by vote) and idea submission in idea crowdsourcing platforms for NPD, we aim to enrich our understanding of these contexts. Furthermore, we review the literature from two perspectives: individuals' own experiences (past performance) and the experiences of others (interaction with peers' ideas) and identify several key gaps in the literature. Using data from a pioneer innovation community for NPD, we find an inverted U-shape association between users' past performance (in terms of average quality of past ideas) and idea quality and idea submission. Additionally, interaction with peers' ideas (in terms of quantity and intensity) positively influences idea submission but does not impact idea quality. A complementary relationship between own experience and others' experiences was also not found. The findings provide new insights into idea crowdsourcing platforms for NPD and the determinants of individuals' idea submission behavior and idea quality on these platforms which have several implications for practice.

A METHOD TO SUPPORT THE IMPROVEMENT OF KNOWLEDGE TRANSFERS IN PRODUCT AND PRODUCTION ENGINEERING

AbstractThe product engineering process as part of the product life cycle includes product and production system development as well as production. In integrated product and production engineering (PPE), knowledge transfer is an important success factor. Optimizing the efficiency and effectiveness of knowledge transfers can, for example, support the avoidance of costly, production-related changes to the product design. The current state of research describes different models of knowledge transfer as well as factors that influence it. Some results show how the speed and quality of knowledge transfer can be improved by implementing so-called interventions. However, those models either represent abstract contexts of knowledge transfer or focus only on product engineering. Therefore, a literature analysis is conducted to identify the system of objectives for a method, that supports the improvement of knowledge transfer in PPE. Subsequently, the system of objectives is operationalized to provide the basis for the InKTI – Interdepartmental Knowledge Transfer Improvement Method, which is applicable, supports the user in improving knowledge transfers in PPE, and aims to increase the quality and speed of knowledge transfers.

Beef tallow/lard blends in O/W emulsions: Characterization of fat crystals, partial coalescence, rheology, and aeration performance

This study aimed to find new strategies for enhancing the stability and texture properties of aerated emulsion by combining different animal fats with different ratios. Beef tallow (BT)/ lard (LA) were mixed at different ratios to prepare oil-in-water (O/W) emulsions, with and without aeration. The compatibility, crystallization behavior, stability, and rheology in both O/W and aerated emulsion systems prepared with BT/LA binary blends were further investigated. Larger and inhomogeneous β′ and β crystal mixtures appeared as the BT ratio increased. Monotectic or eutectic interaction was displayed according to different BT/LA ratios, solid fat content (SFC) and temperatures. O/W emulsion prepared with BT/LA binary showed higher apparent viscosity with larger fat globules distributed as the BT ratio increased. BT had higher SFC at any given temperature and the fat globule aggregation extent was higher. Partial coalescence occurred as the LA ratio increased when SFC < 35 %. Higher foam firmness of the aerated emulsion was achieved by BT/LA binary with higher BT ratios. As a result, combining BT and LA with different ratios achieved higher emulsion stability and foam properties. This study provides a novel insight into the application of different animal fats and the improvement of high-quality whippable products.
