Printing a piano

[agwebberley 0]

Hello everyone,

I am trying to make a grand piano model and I am having some possible issues.  I am new to 3d printing but I have been doing modeling for a while, so your patience will be much appreciated..  

 

Issue #1

The first image is in xray mode in the prepare section, is the red area errors? If so can it be printed with those errors?

Issue #2
The second image in in the prepare section, My main question here is will the print work or will it fall apart, I know that the red means possible overhang...

issue #1 may cause problems.  Or it might not.  You can tell when you slice it and look at it in "preview" mode.  There may be some things missing (not printed) next to the red areas.

 

you are going to have much more serious issues.

 

The red in the second picture is going to need support.  Well maybe not the piano lid - but that might be too thin to print.

 

Maybe you should post your project file so other's can take a look at your model and your settings.

 

I would probably print the 3 legs and pedals separately and print the piano bottom flat on the print bed.  But with holes in it for the legs to stick in and glue in.

 

If you do that then the lid might not need any support - or just a few columns half way up the piano cover to keep the cover from wobbling too much while you print.

Basically, you need supports. Any type of support would work (there are only a few) but it would be a lot of support material.

When designing things for FDM printing, the physical limits of the process have to be in the front of your mind.  Fortunately Super-Glue works very well on PLA and PETG.

If the legs were separate, you could put 2.2mm holes in the tops (3mm deep) and then matching holes in the bottom of the piano body.  Cut pieces of filament to suit and use them as locating pins when you glue the legs on.

If the foot pedal assembly had a plate on top with two locating holes, it would glue right on and be clocked correctly.  Round plates on top of the legs might be helpful both for printing, and to keep them at 90° to the body while the glue sets.

The lid attachment would need some thought but the lid printed flat on the bed would be SO much easier to print.

The main problem would become either the candelabra (Liberace) or the seatbelt (Victor Borgia).

I would definitely make separate pieces to be assembled after printing. You could completely do away with supports.

I see a trip in the 'Way Back Machine.' 😄

I didn't want to be repetitious and a couple of weeks ago I used an Elton John reference.

Mr. Peabody's glasses would be easier to print than Mr. John's though.  Horned rims don't generally require mountings for rhinestones.
