LCD/MSLA Resin Calibration Coupon

Create a precision calibration coupon for LCD/MSLA resin 3D printing and export it as a STEP solid. Overall specimen dimensions: 30.0 mm long × 20.0 mm wide × 1.5 mm thick. All calibration features must be OPEN recesses from the same top face of the specimen. Do not create enclosed internal channels. The opposite bottom face must remain flat. Divide the top face into 3functional zones: -X-direction channel-width calibration. Create eight straight rectangular open trenches oriented parallel to the 30 mm length of the coupon. Nominal trench widths: 0.025, 0.050, 0.075, 0.100, 0.150, 0.200, 0.250 and 0.300 mm. Each trench should be 3.0 mm long and 0.300 mm deep. Keep at least 0.50 mm edge-to-edge spacing between neighboring trenches. Arrange them in increasing-width order. -Y-direction channel-width calibration. Create another set of eight straight rectangular open trenches oriented perpendicular to the first set. Use the same nominal widths: 0.025, 0.050, 0.075, 0.100, 0.150, 0.200, 0.250 and 0.300 mm. Each trench should be 3.0 mm long and 0.300 mm deep. Keep at least 0.50 mm edge-to-edge spacing between neighboring trenches. Arrange them in increasing-width order. -Z-depth calibration. Create eight separate rectangular open pockets. Each pocket should be 2.0 mm × 2.0 mm in XY. Pocket depths must be 0.025, 0.050, 0.075, 0.100, 0.150, 0.200, 0.250 and 0.300 mm. Keep at least 0.50 mm wall thickness between adjacent pockets. Arrange the pockets sequentially from shallowest to deepest. Surface-roughness measurement area. Provide one unobstructed square measurement area at least 4.0 × 4.0 mm. Make this area a broad open recess 0.300 mm deep so its floor represents a printed microfluidic channel surface and can be measured directly using optical profilometry.

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
