Abstract

3D printing is a rapid manufacturing methodology which provides low turnaround times greatly advancing the efficacy of low technology readiness level (TRL) prototyping of opto-electric sensors. Herein, we describe the design and evaluation of a discrete adjustable optical prototyping system, refered to as the Rapid Indexable Positioning System which can be utilized in conjunction with formfitting 3D printed opto-mechanical components to aid in the development of aerospace payloads. “Grid holes” are integrated to an enclosure wall using a grid pattern of holes on every face of a payload enclosure. This works in conjunction with various components that can be semi-permanently positioned with the use of “studs,” allowing for rapid validation of layout within an enclosure. The demonstration of this technique is conducted on prints using both PLA and ABS with the use of a Raise3D Pro2 Printer with the print properties of 20% honeycomb infill and .2mm layer height. The use of this technique in payload enclosure development facilitates rapid and indexable changes to be made, requiring that only a single enclosure, which requires nearly 24 hours to print. This print can be utilized with multiple iterations of each part to be indexed, requiring only about 1 hour. Additional Dynamic oscillation simulations can be conducted to ensure that the optical components would remain within a necessary manifold of deflection once the viability of their final location was verified.
