to 'uil# the !o#el fro! a series of cross sections

These layers" $hich correspon# to the %irtual cros

CONCLUSION

Nothing communicates ideas faster than a

three-dimensional part or model. With a 3D

printer you can bring !D files and design

ideas to life " right from your des#top.

$ %est form, fit and function " and as manydesign variations as you li#e " &ith functional

parts.
