I did a Toastmasters speech on this new technology.
Does it have any application in amateur rocketry?
AeroTech DMS motors now use 3D printed thrust rings.
Wasn't there an incident with a 3D printed rocket at NSL this year?
I think its a great prototyping tool. It just has its own quirks and design factors to incorporate (like z-axis lamination)
Is this correct? I haven't seen anyone else say this. It seems like a strange choice given the conditions at that end of a burning motor.
Yep, I have seen them myself. Apparently they've been tested quite extensively. All the 29-54mm motors have them (don't know about the larger ones). Looks like they're on the RCS site as well: https://www.rocketmotorparts.com/Thrust_Rings/cat1577810_2125751.aspx
Nice!I am in the process of building a Nike Apache and have made use of 3D printing for the NC (4"), payload bay transition (3"-4") and interfin spacers (scale detail and camera mounts) on the Apache.
Like a previous post its all about the application, knowing your process and engineering.
I use PLA (!) ejection charge holders. 3 flights so far, no problems, 3g+ charges.
That is surprising. Short duration must be the reason.I've been wondering if anybody had tried that, apparently the temperature and pressure of the BP charge isn't enough to compromise the structural integrity of the wells. Good to know...
That is surprising. Short duration must be the reason.
I use 3d printed parts in my RSR Kits that Apogee is currently selling. The plastic is ABS which is strong and somewhat light weight.
Acetone processing is one reason to like ABS.
