Answer:
=1.53 hr
Step-by-step explanation:
In your question 30mm should be the thickness. Also, the minimum possible time is required.
SOLUTION:
The part should be oriented on its side in stereo lithography, thus laser Area A is same for all layers.
A= 1/2 (b x h) =>0.5 (36 x 38)
A= 864 mm²
Time to complete one layer 'T' is same for all layers
T= [(A/spot size x velocity)+ last time]
T=[(864/ 0.15x2200) +25]
T=27.62 sec
Number of layers 'n' is given by:
n= t/ layer thickness =>30/0.15
n= 200 layers.
Next is to determine minimum possible time required,
= n x T =>200 x 27.62
=5524 s /60
=92.06 min/60
=1.53 hr
