Show off your 3D printed rocket parts

[Danh]

There is a lot of people 3D printing rocket parts nowadays. Thought it would be cool to see what others are making.

Here is a few things I have printed:


29mm saucer

29mm minimum dia translation to 24mm minimum dia. Still need to finish fincan for sustainer.

Fin alignments

38mm fincan

Ebay bulkheads for usrockets banshee

More fincans and nosecones.

There another thread discussing this here: https://www.rocketryforum.com/showthread.php?137126-3D-printing

Here is a copy of my original post:
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. All the details are here on the build thread:
https://www.ausrocketry.com/forum/viewtopic.php?f=6&t=5019






I also tried to build the fins with a 3D printed isogrid core (bonded to CF skins) but I didn't have time to get the bonding right for the ABS. Went back to a G10 f/g core (CNC routed) for those fins.

The NC has had about six flights on my Velociraptor. No problems.



If the Melbourne weather manages to improve from its unseasonable unreasonableness it is currently showing the Apache will fly solo next weekend on an M840. I'll let you know how the transition goes! It has been designed well for flight, but I am concerned it may suffer "broken chalk syndrome" when it lands. Probably not, but possible.

This page says it all... all of my detail and larger scale parts are 3D printed for my kits. ..website: apogeecomponets.com

I hadn't really considered using 3D printed parts for things like bulkheads, figuring they wouldn't do well with the burning bits/heat produced by the BP. Have you found that not to be an issue, or do you end up coating the exposed surfaces with JB Weld or something to help insulate it?

For use in the rocket itself I've only printed sleds for altimeters and trackers and their associated batteries/cable management. I've been working on a camera shroud for the Firefly Q6 camera (for 1080p/60 on-board video, I've used Landru's shrouds for my Mobius cameras). I've also printed some jigs for drill guides and forming fins and the like.

I haven't had any issues , I do print with mostly abs not sure if it makes much difference. The heat and burning bp from ejection charges isn't there long enough to do any serious melting that I have found. Coating with epoxy would help with cleanup the layers like to collect debris . Which is also why I like abs because I can smooth out the layers with acetone.

For my LPR use I have been 3D printing what could best be called little oddball doodads (other than my fin jigs).

I am finding designing and 3D printing parts to be just about the most fun parts of my builds, even for my silly little thingamabobs. Maybe because the whole thing still seems so improbable and science-fictiony to me.

AIM Xtra with 1000mAh LiPo inside of a 54mm x 6" long bay. Also printed the switch band:

38-29 fin can:

 

[patelldp]

54mm Raven sled. 3" long with broken out terminals for two events. This will be the primary board for my upcoming 54mm three stager. There will be a Raven in each booster with each controlling the separation charge, ignition, and recovery of their respective stage. The previously shared AIM Xtra board will control the sustainer with full telemetry.

 

[patelldp]

Last but not least for now, my ultra compact 54mm altimeter plate for the Altus Metrum EasyMini. Comfortably fits the altimeter, battery and switch in a 54mm coupler only 1.875" total length. Easily got redundant electronics systems inside a 4" long 54mm coupler. Available for sale from my website www.easyresearchrocketry.rocketryspot.com.

 

[patelldp]

Definitely last for now...I am getting ready to break ground on my LOC Ultimate, a 7x 29mm cluster rocket using the cases that I sell. I printed new CR's for the build and a fin alignment guide to assure the fins are perpendicular to the tube.

The twist lock nosecone is very cool! I like it!

What material are you printing with? Have you noticed any deformation from the ejection charges?

 

[new2hpr]

Dan,
Nice Ultimate you've got started! I hope you've taken into account the thrust rings on your cases (or maybe your research cases have smaller rings?). I had to tweak the hole spacing on the rings from LOC in order to fit Aerotech cases in all holes, but they still fit!

Look forward to seeing what you stuff in it.

Yep, they fit. I'm having a retaining ring machined that will look a lot like the CR and will retain the motors via their thrust rings.

Sized for 38mm. Planning more prints in the future. Lots of fun AV bay stuff to mess around with.

Dan;

I could have sworn I responded to this already, but here goes again.....

I'm using ABS for all my printing. Haven't flown with this exact baffle yet so I can't provide experience on THIS part. However I've had a few flights now using ABS bulkheads and haven't seen any evidence the material is being affected at all. I'm also using Doghouse charge wells on a couple rockets, which are PVC, and those are holding up quite nicely too. So considering the dwell time and such for the exhaust gases I'm not concerned in the least. Worst case, all I'll be out is a body tube as it's the upper section on the rocket I'm building, and all the fins and motor mount are in the lower. I'm also thinking about my Mosquito which I use a nomex wrap on the chute, and the nose cone gets a pretty regular blast of ejection charge from a closer distance. That nose is ABS as well and hasn't seen any issues. I fly the hell out of that Mosquito.

I recently made this tail cone for a 54mm MAC Performance Radial Flyer. I thought that the use of a boat tail motor on the 3" version really made the profile of the rocket, but there's no such option for the 54mm size with a 29mm mount. So I designed this piece to do the job. I tried to balance mass and structure, making it robust enough to tolerate a rough landing without adding too much weight to the wring end. The large counterbore on the aft end is to allow a 29mm Aero Pack retainer to be partially recessed.

3 screws works, too. :wink:

Now you guys have me wanting a 3D printer, with all these cool ideas.
It would be useful info for each of you to note what kind of printer (and filament) you're using.
Thanks,

Anyone know if anyone has ever tried 3D printed fins with an airfoiled, light weight geometric internal structure (I'm visualizing a skinless WWII Wellington bomber) with an epoxy adhered skin, say Tyvek?

 

[BEC]

https://bigrep.com/bigrep-pro-ht-high-temperature-resistant-filament/

How (or where) did you acquire that material? It sounds very intriguing (my first 3D printer should be here soon) but it's shown as "not available" in the site to which you linked.

No, but I have done an isogrid core of G10, CNC routed, with CF skins. Tried a printed ABS core but adhesion was not predictable.

I have a da Vinci 1.0a flashed with repetier .92 and use simplify3d for my slicer. I mostly print with abs but have used everything from ninja flex to nylon.

[patelldp]

I have a Monoprice Maker Select i3 v2 (https://www.monoprice.com/product?p_id=13860) that I have modified per the Wiki articles online (https://3dprinterwiki.info). Biggest mods were the z-brace to solidify the z-axis, adding a glass printing bed, then printing a new spool holder and filament guide. Printers are almost like milling machines...you can upgrade them extensively by printing parts on the actual printer you intend to upgrade!

The printer has logged 15 days and 20.5 hrs of print time and has worked its way through 1149.1m of filament without a single clog using the off-the-shelf extruder.

I use Cura as my slicer software and Hatchbox filament from Amazon. If someone is interested in learning my settings, shoot me a PM.
