About Project

To celebrate the completion of the new underground line, Metro Bureau ordered this commemoration model. The enclosure is part of the subway station, on the inner wall of which is the relief of rails, the escalator, windows, etc. The name of the subway is carved on the front while its logo is on the top. The spiral lines symbolize the tunneling subway, which are hard to produce under traditional manufacturing methods.

Solution

• Step 1: Check the blueprint and STL file to ensure the model is printable. As requested, the spiral lines need to be fixed onto the back wall by sticking into the holes. Thus we need to adjust the diameter of the holes and the rods for the stability of those lines. Also, the lines do not meet each other so they need to be connected by the rod.
• Step 2: Manufacturing the enclosure and the spiral lines separately with SLA 3D Printing technology using SLA Tough Resin. Produce the connecting rods with CNC milling. The resin base is solid while the thick line is hollowed.
• Step 3: Remove the supports, rinse with IPA, and post-cure the prints with UV. Be careful when polish the holes. Paint the lines, the ceiling and the logo.
• Step 4: Connect the lines with a rod and fix them onto the back wall with two other steel rods.
