The Last Supper 3D

pinshape

Leonardo Da Vinci's "Last Supper" sculpted in relief for 3D printing includes a separate frame model, making it easier to finish and print. Both models can be printed quickly without any support or cleanup required. Instructions: Requires a build plate size of at least 191mm x 152mm for a successful print. A perfectly level and clean build plate with plenty of adhesion is essential due to the large size of these models. Otherwise, they are easy prints with no overhangs. Print picture at 0.1 mm, 20% infill, no support. Dimensions: 152mm x 60mm x 4.5mm. Print frame at 0.2 mm, 15% infill, no support. Dimensions: 191mm x 94mm x 8mm. Finishing: Spray paint that bonds to plastic over the entire surface. Mist on the first coat so it only becomes tacky. Spray from each edge at a 45-degree angle, covering all sides. Once dry, spray an even coat again at a 45-degree angle, starting and stopping before reaching the piece. Repeat until satisfied with coverage and finish. Let dry completely. Seal with a light coat of acrylic sealer, preferring matte or satin. This step is essential for the next process. To shade valleys in the picture, use dark brown or black ink or paint. I prefer ink because it stains well without sticking to acrylic. You can experiment with various options: oil, watercolor, pastels, or ink. Pour a small amount of ink directly onto the painting and let it flow into lower points naturally. Use a brush to spread it around until satisfied, then dab off excess ink with a paper towel. Seal again with acrylic sealer. Try dry brushing on highlights or running white pastel/chalk across ridges for extra effect. Assembly: Notice three triangle-shaped openings inside the frame's ledge: one at the center top and one on each side. This is where you'll insert wedges to hold the picture in place. Slide the bottom of the picture into the frame, push it down, then forward. Break apart wedges and insert them one by one into the little openings to secure the picture firmly. Hang using the hole at the top of the frame.
