Matlab logo is copyright The Mathworks. I make no claims to have created this logo, I just uploaded it because I thought it was cool! Made with Matlab and two projects from the Matlab File Exchange: surf2solid by Sven http://www.mathworks.com/matlabcentral/fileexchange/42876-surf2solid-make-a-solid-volume-from-a-surface-for-3d-printing and stlwrite by Sven http://www.mathworks.com/matlabcentral/fileexchange/20922-stlwrite-write-binary-or-ascii-stl-file Thanks Sven! Logo itself is the L-shaped membrane, which is an eigenfunction of the wave equation.No supports should be required, STL is manifold, should be as easy as load, scale, and print! Use infill to reduce print times.
