First 3D Print

[robcat2075]

I got a 3D resin printer.

My first print is the teapot from the Three Teapots Benchmark

 

As it is printed on the build plate. This took one hour to print. At this scale the walls are paper thin.

 

After curing and removing the supports:

Cool!  Are you planning any special projects with it?

Yes, I still have contest medals to make!

Layer lines can be observed on shallow slopes. These are 0.1mm layers. I think they can be made smaller in exchange for longer printing time.

The 3D print is pretty good but consider that the penny has finer details than this 3D print could show.

Is there any kind of chemical treatment that can eliminate or reduce the lines?   You probably can't really see it unless you are right up on it, though.

Maybe. But the last thing I need is more chemicals for this.

True.  Looking at the first 3 photos, the model looks pretty smooth.  You can really only see the lines when you are zoomed way in.

Cool!!....resin printing is a bit tricky with all the chemicals but if anyone can do it right...it is Rob!

My local public library has a 3d printer that I have used for simple printing dice.however I want to print some more complicated things which brings up a question. 

What happens when you have a 3d model sitting on top of (but not connected to)  another 3D object (see attached). It is a sphere just sitting on top of a cube.

If that is exported as an STL file, will it print it like a sphere on top of the cube or will the fact that they are not connected with splines confuse the printing software?

 

Thanks for any clarifications!
