Abstract
Fused deposition modeling (FDM) is suitable for various mobile occasions due to its significant advantages, including a relatively low cost, high reliability, comfortable mobility, and low energy consumption. Nevertheless, limited by the energy density and power density of the mobile energy storage system, the printing service time and health status of the present FDM printer leave much to be desired. In this work, we derive the first survey on energy analysis of a mobile multi-material FDM by separating a full printing cycle into different operating phases, of which the individual energy consumption is analyzed. In consideration of the switching between materials with different melting temperatures, which might require significantly varying power inputs, a hybrid energy storage system consisting of both a battery and a supercapacitor is developed. In addition, by governing work mode switching based on the prediction of power changes, an energy management strategy is finally realized to meet the design requirements.
Highlights
Fused deposition modeling (FDM) is considered as one of the most important subset of additive manufacturing (AM) techniques for building a 3D complex structure by melting and extruding filaments of thermoplastic polymer materials through a small diameter nozzle onto a building platform
Their relatively low cost and high reliability have been advancing the mobile applications of FDM 3D printers in humanitarian relief,1–3 field research exploration, telemedicine,4,5 extreme environments,6–8 and space missions
In an extreme environment such as a nuclear plant to which the operators cannot be exposed for a long duration, Hunt et al.13 have implemented the printing experiments in complex nuclear environments by altering the 3D FDM printer into a drone carrying an extruding head, which helps in removing the nuclear wastes
Summary
Fused deposition modeling (FDM) is considered as one of the most important subset of additive manufacturing (AM) techniques for building a 3D complex structure by melting and extruding filaments of thermoplastic polymer materials through a small diameter nozzle onto a building platform. Their relatively low cost and high reliability have been advancing the mobile applications of FDM 3D printers in humanitarian relief, field research exploration, telemedicine, extreme environments, and space missions.. They enabled two mobile printers to work together and be linked for efficient and fast manufacturing in the very near future
