around the selected volume. The number of triangles determines the quality of the
reconstruction: the more the triangles, the higher the quality [

].
(k) Importing the geometry to ANSYS:
ANSYS is an engineering simulation software developer. The humeral head is
fixed and the elbow is considered a motor rotation couple having some angular
variation. The load is applied according to the force values calculated with respect
to the angular variation (Fig.
2
). The parameters like total deformation (Fig.
3
),
Von-Mises Stress (Fig.
4
), maximum principal stress (Fig.
5
) and equivalent strain
(Fig.
6
) are calculated.
Steps Involved in RP Process
• The STL files are checked for flaws within the file.
• The data have been sent to the machine for the Stereo lithography (SLA) process
to take place which is the most widely distributed process of RP.
• A photosensitive liquid, i.e., a photopolymer resin that solidifies when exposed
to light, is in a vat.
• A laser, emitting ultraviolet light, is placed on top of this vat.
• The movement of the laser light on the surface of the resin is controlled by a
movable mirror, using the data from the STL files.
