Manufacturing and Security Challenges in 3D Printing

Implications of Malicious 3D Printer Firmware

“…Zeltmann, et al, [33] investigate the impact on tensile strength of two types of manufacturing modifications, sub-millimeter scale defects in the interior of 3D printed parts, and orientation of the part during printing. For the first defect type, cubic defects in three sizes were introduced by replacing main material with a contaminant.…”

Optimal sabotage attack on composite material parts

“…Compromised elements include computers that store design files and control the manufacturing process [2,6], communication networks that connect these computers with the robotized manufacturing equipment [23], the firmware installed on the equipment [24,25], or even an in-situ quality control system [26]. These compromised elements can stage a variety of manipulations, including tampering of the design files [2,6], manufacturing parameters [7,8,25], manufacturing process status information [26], and altering communication timings or power supply [27,28].…”

The Influence of 3D Printing on Global Container Multimodal Transport System

“…If printed by consumer themselves, they are not as good as from professional enterprises. Zeltmann et al (2016) found that if 3DP was performed in a decentralized environment such as being homemade, there was risk of strength and durability in the finished product due to lack of qualified inspection [18]. The case of UPS Company (Dong et al, 2016) showed that in the 3DP era distribution provider is fully capable of acting as a qualified end-manufacturer [15].…”
