NASA Tests Feasibility of 3D Printing on the Moon & Other Planets Using In-situ Materials and a Really Hot Laser. From

…Using basalt regolith (BP-1) and lunar basalt simulant (JSC-1A) as building materials for their robotic additive construction, they were able to test to see if this method of 3D printing the in-situ resources on the moon and other planets could be feasible. Researchers needed to come up with a way to take this regolith found on non-terrestrial surfaces and then harden it in a way that it could be used as a building material. Some of the methods available to do this include solar heat sintering, microwave sintering, polymer binders, compaction, regolith paste extrusion, and lunacrete forming. After careful examination, the KSC researchers “selected laser heating using an infrared laser as the most direct method to deliver a sufficient amount of energy into a small volume that will allow granular regolith particles to fuse together.”

The preliminary results are quite interesting:

“Flexural strength testing (3 point bending) was performed on test coupons of solid processed BP-1 and JSC-1A using an Instron load frame testing machine and 100 kN (22,480 lbf) load cell. Multiple samples and tests were conducted for repeatability. Test results indicated that the samples had strengths better than residential concrete, and similar to some weaker glasses (Bon,2003). Testing of useful shapes beyond test coupons has focused on structures with unsupported spans (which pose a challenge for any Additive Manufacturing process), including cones, hemispherical domes, and ogive domes.

…NASA KSC says that the results have been promising but we must consider the fact that they are only at a “bench top scale.” Researchers are continuing to work on the development of this innovative technique, as well as issues that they foresee arising….

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! We also offer the LulzBot TAZ – Open source 3D Printer and the Printrbot Simple Metal 3D Printer in our store. If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Join 16,000+ makers on Adafruit’s Discord channels and be part of the community!

Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7:30pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.

Join us every Wednesday night at 8pm ET for Ask an Engineer!
