Stereo lithography, which is mostly use for rapid tooling applications, is the earliest
technique developed for rapid prototyping. It converts CAD models directly into real parts,
which offers the considerable benefit of shorter lead times and less waste. Layer thickness,
build orientation, exposure time, and other process variables all affect the strength of
part produced via masked stereo lithography. This work aims to identify, investigate and
maximize the influence of process variable on the part produce by Anycubic Dental non
castable resin in Anycubic Photon S LCD SL printer. To do this, L9 orthogonal array
designed using the Taguchi method has been developed, which lowers the number of
experimental runs compared to other approaches. In addition, an empirical regression
model linking part strength and process variables such layer thickness, build orientation,
and exposure time was created. Prior to physically fabricating the item, this process model
may forecast the amount of strength that can be attained for the specified set of process
parameters. Additionally, the model demonstrates how strength is dependent on the
specified process parameters, which is particularly beneficial for technical individuals like
designers, engineers, and RP machine users.
