Official 3DP Thread

[Elbee]

RCJD, Well, I thank you, though it looks differently from this side. Your talking about a guy that can't draw a stick figure without circle templates and a ruler. It is a slow process and nothing when compared to what others have and are doing here with 3DP. Nonetheless, I really like doing it. I would be building these things using 'old school' techniques anyway, so it saves a lot of running around looking for fabric, plastic shapes, tubing, lite ply and bits to recreate the same details. Trouble is with all this great tech, I keep thinking it should be 'dam^ near perfect and like most of us, I am my own worst critic. Hope to be posting the STL files soon. Humbly, LB

Hey Ya'll, Working on the LB Ejection Seat for my F-18C which is guaranteed never to eject anything from anywhere and that's a promise. Again trying to keep the parts count minimal and light, though easily assembled. A work in progress and a bit clunky yet, but getting there. Best, LB

Clunky? Hardly! You amaze me with your skills sir.

That sounds great. I will be looking out and checking your progress. Your cockpit and the mods from RCJETDUDE are all the additions I would like to do to my jet. As a second jet I was thinking about the new Eflite 80mm F-18D or the Banana Hobbies LXF-18F(as a Growler). Both models have fantastic looking scale gear. I wonder if they would fit my Motion Jet.?

[Elbee]

Hey, that looks great and something I would gladly pay for the file when you make it available. Is there a seat that goes with it?

DM, Yes, the seat will part of the file set. I am working on it, . The files will be posted in this forum when complete and I am satisfied with the results at 'no cost'. The joy is in the doing. I have done 6 tub configs and I am still not yet pleased with the design or the part count, though it's coming along, I think. The picture is a single print and hopefully only requires the LH/RH Instrument panel height to be corrected to proper scale. Console widths are an issue for pilot choice and mod at 1.5625", so some minor surgery will be required. No biggie for modelers, right? I have not built my Freewing F-18C, so exact battery placement is a 'SWAG', but with the extra weight of the 3DP parts in the forward fuselage I think battery placement will move aft enough to make space for the deeper tub and 'pit'. I will post more pics as the work progresses. Best, LB

Hey Y'all, Finished and printed a set of the LH/RH Consoles. Plenty of detail, though I will try a print with the consoles laying 'flat' and see if it ups the resolution some. It is looking like it will make more sense to add these to the 'tub' for a finished print. Also, will need to push these a bit outside the tub walls to add some interior space for the pilot. The OEM foam walls on the air-frame are scaled nicely, but thick, so to stay within some semblance of interior scale, the pilot will be a snug fit. It'll all be good, I think. Best, LB

Amazing work sir! Just top notch stuff.

[Hardway]

Nice work bro!

I will be printing in ABS. the one pictures was another RCGroups member who printed in PLA. The original designer printed/flies his in PLA, but he lives up in the arctic circle where it is normally cold.

[Elbee]

haha, yup it does remind me of another cockpit set.The braking system might be scale-able, but would need some alterations for different O-rings and servos to operate the cams. I plan to 3d print the 120mm housing and fan that the designer made for the model. He seems to have good efficiency with it, and can get 5 minutes of flights on a 5000mAH 12S setup.

Chris, Whoa, you're printing the fan? Which material for that? Amazing to me, though I am easily entertained most days. Best, Steve

There is a Gas Turbine section under Power Systems. I am not converting any of my EDFs to turbine (like Jan Berg has been doing). But there are some foamy turbines on the market today from HSD and now Global Jet. But for now I'm sticking with composite jets.

[Dirty Dee]

Chris, I thank you, Sir. Does the design remind you of another cockpit kit? I am coach-able. Wow, what a great new project for you, I am envious. That is one large 3DP airframe! Do you think that the 'braking system' could be scaled down? Which EDF system will you be using? Best, Steve

CRXMP, Very cool. Are you converting 'foamies' to 'turbine'? Is there a "turbine-based'" forum on this website? Best, LB

[crxmanpat]

Haven't been doing much printing lately as I've moved up to turbines, but I did print something nice yesterday in ABS. Most turbine engines come with a FOD screen that slides on the front and is held in place with an o-ring. It's a pretty secure fit, but we all know that o-rings dry out and break eventually, especially since I live in a very dry climate. A friend designed a cover that uses existing screws in the nose of the turbine to secure it in place. It's printed in ABS because turbines get hot.

These fit most Kingtech turbines except for the very small and very large ones.

Looks great Steve. I decided to try out one of lynxman's designs and started printing out the L-39 in ABS. A lof of the fuselage parts need a 300x300mm bed, so I will be needing to split the parts to fit the prusa, or possibly purchase an artillery sidewinder or jgaurora a5s. The smallest fuselage section that fits on the prusa takes 18hours

Well Hulloo All, Still plugging away, though I am progressing. There are 6 parts in the photo and I think that is what it will take, but hope to make the RH/LH side consoles part of the "Tub". The MB Ejection Seat is a bit tedious and so far has a high part count. Not certain whether to simplify it as most of these are or stick it out and make it a little more detailed with 'Some Assembly Required". In any case, I will keep up the 'good fight'. Best, LB

Hi LB, how o I go about getting this file for my FW F-18?

Hey DM, I will post the STL Files for this when I have proven the design, i.e., when I have finished my F-18 and all the parts fit well. The 3DPUP thing has become part of the "hobby" for me and I enjoy it, but it is not something I work on everyday. I understand that you want to add a cockpit to your F-18 and so do I, hence taking the time to build the files. I post designs so whoever wants to print my stuff can and I do it at no cost. Not that there's anything wrong with capitalism, but there's in lies the rub, if I charge you, then I am responsible for the prints and shipping and who knows what else and that takes away from all this being a hobby for me. I hope that I haven't offended you in any way with this, but if you are patient, all will be revealed. Best always, LB
