In a vat photopolymerization process you are building with t

In a vat photopolymerization process, you are building with the STAR-WAVE build style under the following        conditions:

      Layer thickness = 0.005\"; Penetration depth, D_p = 6.2 mil; Critical exposure, E_c = 9.5 mJ/cm² (SL-5240);       machine = SLA Viper Si2: Power at vat: 100 mW; Beam diameter = 0.25 mm; Part drawing speed = 5 mm/s.

      a) Determine the cure depths C_d1 and C_d2 needed.

            b) Determine the laser scan speeds required for C_d1 and C_d2.

please answer b

Click \"Select Samples\".Photopolymerization processesbuild use of liquid, radiation-curable resins, or photopolymers, as their primary materials. Most photopolymers react to radiation within the ultraviolet (UV) vary of wavelengths, however some actinic radiation systems square measureused likewise. Upon irradiation, these materials endure a chemical process to become solid. This reaction is named photopolymerization, and is often advanced, involving several chemical participants.
Photopolymers were developed within the late Nineteen Sixties and shortly became wide applied in manyindustrial areas, most notably the coating and printing business. several of the shiny coatings on paper and cardboard, as an example, square measure photopolymers. to boot, photo-curable resins square measureemployed in medicine, like for protection the highest surfaces of teeth to fill in deep grooves and stop cavities. In these applications, coatings square measure cured by radiation that blankets the organic compound while not the requirement for patterning either the fabric or the radiation. This modified with the introduction of stereolithography,the primary vat photopolymerization method.
