The client was a military enthusiast and ordered a four-floor scaled-down ancient watchtower. It has a relatively complicated structure and thin rails, so we decided to split the model into the stone facade, each floor and a roof, and a corridor.
Solution
Step 1: The client downloads the model from the Internet and sends it to us for examination. For printing convenience, our engineer splits the model into different parts, and add snap-fit structures.
Step 2: We arrange the parts in software and add necessary supports. Then 3D print them with black resin material. The layer thickness we set is 0.05mm and we control the tolerance within 卤0.2 mm.
Step 3: When printing is completed, rinse the models with IPA and post-cure them with UV. Cut off all the supports, then polish with sandpaper.
Step 4: Assemble the parts together and adjust the allowance of the snap-fits.
