Based on the test print results, the ground control team sent commands to realign the printer and printed a second calibration test on Nov. 20. These tests verified that the printer was ready for manufacturing operations. On Nov. 24, grou

7、nd controllers sent the printer the command to make the first printed part: a faceplate of the extruder's casing. This demonstrated that the printer can make replacemeparts for itself. The 3-D printer uses a process formally known as additive manufacturing to heat a relatively low-temperature pl

Wilmore installed a new print tray, and the ground team sent a command to fine-tune the printer alignment and printed a third calibration coupon. When Wilmore removes the calibration coupon, the ground team will be

10、 able to command the printer to make a second object. The ground team makes precise adjustments before every print, and the results from this first print are contributing to a better understanding about the parameters to use when 3-D printing on the space station.“This is the first time we've ev

11、er used a 3-D printer in space, and we are learning, even fromthese initial operations, W”erkheiser said. “Aswe print more parts we' llbe able to learn whether some of the effects we are seeing are caused by microgravity or just part of the normal fine-tuning process for printing. When we get th

12、e parts back on Earth, we' llbe able to do a more detailed analysis to find out how they compare to parts printed on Earth.”The 3-D Printing in Zero-G Technology Demonstration on the space station aims to show additive manufacturing can make a variety of 3-D printed parts and tools in space. The

13、 first object 3-D printed in space, the printhead faceplate, is engraved with names of the organizations that collaborated on this space station technology demonstration: NASA and Made In Space, Inc., the space manufacturing company that worked with NASA to design, build and test the 3-D printer. Ma

15、he printers, ” Werkheiser said.“If a printer is critical for explorers, it must be capable of replicating itsown parts, so that it can keep working during longer journeys to places like Mars or an asteroid. Ultimately, one day, a printer may even be able to print another printer.”Made In Space engin

As the first objects areprinted, NASA and Made In Space engineers are monitoring the manufacturing via downlinked images and videos. The majority of th
