Summary

My second attempt to a printable trumpet.

Sounds a bit hazy, still.

Mr. hello
Why didn't I file horn mouth
Thank you

Got any recommendations for printing the bell? I have tried a few times and it keeps breaking apart on the rim. I have tried with a raft and support and still nothing. I ran it through netfab and it didn't help. I am going to try and up the perimeters and see if that may help. I got everything else printed and looks good.

Cant wait to finish printing this! Could you upload instructions telling which part goes into which? Thanks!

All the pieces have printed beautifully except for two, the bell and it's conjoining piece (30-100). The bell of the trumpet breaks apart at the edges and doesn't fit tightly whatsoever with the next piece. The layers on the bell also don't hold in some spots. Did you print it on a raft and/or with support, or at high resolution? I saw in the remixes a conjoined version of the two pieces, but wanted some advice before I continue.

Do you print with raft and support?

Printed this almost twice. I would like to see a list of the order it has to be assembled as i am puzzled by the fact that one of the files contains 2 parts (which in my book is a no-go)

How can you play different notes without keys in the trumpet???

i am a french horn player and back then the french horn had no keys and looked very similar to this. in order to play different ranges you would have to change the length of tubing or the slides. for this you can only play certain notes which are in the register.

Ever wondered how a trumpet can play so many notes with only three valves? You can play "natural notes" on a trumpet without valves.
These are multiples of the ground frequency (230Hz).

Multiplier Hertz Tone (in Bb)
1 230 C
2 460 C
3 690 G
4 920 C
5 1150 E
6 1380 G
7 1610 Bb
8 1840 C

We just buzz a different tone through the mouthpiece and the trumpet follows.

I've been printing the parts for this for the past few days. Everything is going well so far! Definitely a lengthy print when you combine the times for every part lol

I'm in the process of plating all the parts together in Makerware as I type this. It's fairly easy to pack them together pretty tightly, I should be able to do it all in one print, but if not I can definitely get it in two.

Never thought about doing that, but definitely a good idea as long as you're up to the task of putting them all on the platform like a puzzle. Sounds like a good remix item to me

It's a little easier than a puzzle since the curve in 13 of the pieces is very similar, they almost nest. I am printing it at this moment. If it comes out right on the first time, I'll definitely post the remix. It's estimated to take 90-95% of the time as printing all the parts independently, but at least I can do it all in one shot and not have to worry about swapping out build plates or loading up the next print. I was able to get everything but the mouthpiece and the large end piece in one plate under 120x120mm. I might play around with it more, but I don't think it will be possible to get everything on one single plate without a 250x250 build area.

What's the time estimate on your version?

Hey Tinman. Unfortunately my first version did not come out perfect, I had two parts nested thinking they'd have enough clearance, but it was no good. I then moved them around and resaved the .STL, but now I can't get it to slice (in RepG OR Makerware). So I'll keep trying, but if someone else beats me to it, I won't be surprised.

It took me about two weeks, just to find the time to print the entire thing.

I have no idea how to play brass instruments, so it'll be interesting trying to get it to work correctly. I just wanted to be the first downloader to print the entire thing and add it to the "made" section haha

does it accept some kind of standard mouthpiece that can be used on an actual instrument? cool idea

It accepts a regular trumpet mouthpiece. If you don't have one, print this one: http://www.thingiverse.com/thing:44422http://www.thingiverse.com/thi...

Robo, awesome concept!
I think it sounds pretty good. I
started printing (my wife teaches music technology and "has to have one" to show
her students) but I think some of the sections are missing from the files:
400-500, 900-1000, 1000-1100, 1100-1200.
That is, if I am understanding your numbering methodology. I tried the customizer, but could figure out
which numbers adjusted what and what the units were. Any help would be appreciated. Thanks for sharing your model (love the mouth
piece model by the way).

Robo - in reply to dkarch

I uploaded the missing parts. I'll have a look at the openscad-model to make the parameters a bit easier to understand

dkarch - in reply to Robo

Thanks, I'm back to printing again, my wife will be a happy camper!!! I'll post an "I made one" when its done.

I think you are correct, as if you look at the picture, there are 15 distinct pieces (including the mouthpiece) and he only has 10 files for download.

I don't see the mouth piece in the list of printable items. is it missing?

He has a mouthpiece customizer that you could use.

Take the STL, it should be the same as in the video. Print in fine layer resolution (<0.2mm).

Thank you Robo, and thank you for the missing pieces.
