NASA Challenge: Human Rated Spacecraft 3D Printing Process Animation

Medium

The thermal protection and passive thermal system Technical Discipline Leads (TDL) at the Johnson Space Center are in need of a visual aide and short concept demonstration animation that shows a new automated manufacturing process, using robotic additive manufacturing methods, being pursued for development as part of the effort to address the existing technical gaps for future human exploration missions.

The 3D rendering of the envisioned concept, with short animations showing the printing process of a spacecraft thermal protection heat shield and pressure vessel (see guidance below), will help the TDL’s convey the ideas to NASA management, universities and private companies for funding and partnership opportunities in this development endeavor.

Requirements

  • JUDGING CRITERIA

    1. The graphics and animation should depict a modern automated manufacturing site in which large space structures, note dimensions in above sketches, are being fabricated and covered with thermal protection materials. The materials would be deposited on the structures using additive manufacturing deposition techniques.

    2. The artistic concept should be original and not copying the robots shown in the Partner Space. Orion structural images found in the internet can be used as guidance and included in the project. Other vehicle concept could be used but should be submitted for approval by the TDLs before they are included in the work.

    3. The rendering must have a realistic appearance with the proper scaling and the space structures depicted are not limited to those in the Partner Space.

  • TECHNICAL REQUIREMENTS

    The process should show two robotic arms performing the printing and final machining of the thermal protection system material.

    A feed-bay where multiple printing heads reside should be considered as part of the CAD.

    The CAD must show some form of material storage (mixing tank) or filament feed system for the printing process.

    The process should show the deposition on a composite material structure for the thermal protection system printing.

    There must be a separate CAD showing the 3D printing of a metal spacecraft pressure vessel structure.

  • SUBMISSION FILE FORMATS

    CAD files in STL, STEP
    Animation in COLLADA and FBX

    Which material you want to print with?
    How it should be printed?
    From NASA site about Orion heat shield :"The titanium truss structure has a composite substrate surrounding it."
    How it is possible to print metal on top of composite?
    Explain, please, the technology you want to be rendered by participators.

    Hi Azamat, Notice that there are two materials to be printed, one is the thermal protection material and the second is a metal structure. The thermal protection material to be printed would be a paste like material. It would be similar to a clay or concrete extrusion. The thermal protection paste would be the material to be extruded on a composite structure.

    A bit disappointed by this challenge. Grab Cad challenges usually ask the community to design new products and develop new concepts and ideas.
    Here, it looks more like a "low cost" (compared to what it would cost if asked to a dedicated firm) rendering project.

    like those launched by the site "launchfort / NASA."
    It is therefore a matter for creative graphic designers.
    The engineering approach is a bit too far from what you ask for...

    What a cool challenge! Just started yesterday and I'm onto a pretty good idea and hope to get a WIP up early tomorrow which I’ll add to over the course of the challenge.

    The challenge does have a lot of hidden facets and is a bit under documented technically and visually, so I'll be sure to share my 3D and my plan for creating these animations, and maybe it could help others looking for a direction, or to enhance their own concept.

    I will share that I’m creating ALL of my 3D using SolidWorks CAD, and will either render/animate this in Modo, or the Unreal Engine. The challenge definitely belongs here on GrabCAD, but you’ll have really to s-t-r-e-t-c-h yourself to round up these project goals if you only have a few disciplines in 3D, or only use to create just the basic products.

    Thanks for bringing this to GrabCAD NASA !!

    In the first paragraph under judging criteria it mentions, 'note dimensions in above sketches', but there are no images. From this I assume that there are accompanying sketching somewhere for us to use as reference? My apologies, as I am new to this, but it seems like there should be some more specific instructions/specifications for this contest. Am I missing a link to something else or to some additional content? Or is there a page with better/further instructions?

    Thanks...

    Good evening to all. We are glad to see so much interest in this challenge. I will try to address the common questions regarding this challenge. You will find that the challenge is to come up with the CAD of the robotic arms (to protect companies IP this needs to be an original design) and needed equipment for the additive manufacturing process of a human rated spacecraft. Specifically the TPS and pressure vessel portions of the spacecraft. Additional points will be given If a short animation showing the process is provided. NASA is currently engaged in developing this technology for future exploration spacecrafts. Your work will be help us in this effort.

    -What's the ablative material: honeycomb filled or 3D woven fabric?
    -Do you want, in the case of using honeycomb, that the machine procced to the fillin of the cells (injector assisted by a camera)?
    -Do you want to stay with a robotic arm or a cast aluminium gantry with a 2 or 3 axis head with a "suffisant" gooseneck could be suitable?
    -What kind of rigidity/precision is necessary? (+/- 0.01 or+/- 1mm; also metal machining?)
    -For the greater vehicle, what's the size of the parts to be processed? (9 meter wide x 20 meter long x 3 meter height?)
    -What are the tools you want to fit on the head(s): electric spindle, PU printing head or glue applicator, solid depositing material (powders)...

    I'm not sure i will participate but the answers to those questions could help many to produce suitable ideas, (i think!).

  • Angel Alvarez

    Angel Alvarez 18 days ago

    Clarification to the community: The proposed design needs to show a system that is capable of printing a human rated spacecraft heatshield and pressure vessel separately (Orion heatshield/pressure vessel preferred). Take a look at file 2.png. As an example, this could be modified to have the robotic arm deposit a slurry to print the heat shield using a rotating table. The design would just modify existing technology (robotic arms or 3d gantries) to accomplish the manufacturing process. A similar and separate configuration could be created for the pressure vessel. Use human rated spacecraft samples (Orion design preferred) that are currently being developed. Avoid the use of futuristic spacecraft designs. Take a close look at the requirements section. Please advise if there is anything missing, or if there are any areas where clarification would be needed. Thank you and good luck to all!

    Good afternoon to all,
    I wanted to take the opportunity to address concerns regarding the extension of this challenge. We have decided to extend the challenge by 2 weeks in order to allow the opportunity for additional members of the community to submit their proposed designs, and for current participants to make any modifications needed. Without a doubt submissions made by Aug 10th at 11:49pm EST, will be given consideration during the selection process. Please read carefully the requirements and the additional clarifications made in the comments above. The design submitted should show the heat shield portion of the vehicle being printed with the proposed method. The CAD of a partially printed heatshield would help convey the idea of the process. Thank you again for your participation and hard work. Best of luck to all!

    I’m working on another entry and I have a few quick questions about the thermal layer:

    1) About how thick is thermal layer applied? .25-inch, 1-inch, 3-inches? Also, is it traditionally applied as one single layer, or is it comprised of several layers? Or it that up to us?

    2) What’s the consistency of the thermal material? For example is it nectar-thick, honey-thick, or pudding-thick?
    ...
    Thanks in advance!

    Tommy, You can assume that your heat shield is printed by depositing roughly +/- .5" layers of the ablative material until completing the overall thickness. Currently manufacturing a heat shield involves a 9 step labor intensive process (see second link on @Tarik Cs post) where a honeycomb structure is attached to a titanium base and filled with ablative material. The consistency for the proposed AM process would be similar to the concrete extrusion shown in the YouTube video I posted earlier. I hope this helps.

    Rather than using existing systems like gantry system or other pre existing systems can I introduce new system something innovative system... which will be possible & may be useful...
    May be useful for NASA like camera shutter simple mechanism used to grab objects in space.

    Like this concept of grappler comes from camera shutter
