Post-Printing The post-printing process begins after printing is complete. The goal is to create a smooth surface and lower friction between parts. Several pieces will need to be carefully glued together. First, glue the four scroll parts together as well as the two shroud parts. How I Designed This This innovative design is based on the combination of a radial compressor and an air raid siren. The theory behind the air raid siren revolves around its use of slats to interrupt airflow from a rapidly rotating fan, producing sound waves through the creation of fast-changing pressure and amplifying it according to the magnitude of the pressure difference. The radial compressor was designed to compress air into a smaller space than what is typical in an axial compressor. The compressor takes in air that enters the blades, accelerating it into the scroll. This gradual expansion converts velocity energy into pressure energy as it gradually opens towards the exit. By merging these two theories, we create a uniquely crafted noise maker that utilizes principles from both sound-making phenomena. The design allows air to accelerate through the blades at a high speed of approximately 5 meters per second and then is disrupted, generating significant pressure variations which amplify the sound produced. This amplified sound is further intensified by directing these pressure waves into a singular direction as well. To solidify the theoretical foundations behind this design, all parts were modeled using computer-aided engineering software and meticulously tested to ensure that our predictions held up under actual circumstances. The end result is a masterpiece of mechanical sound-making precision.

First, push parts 1 and 3 together firmly; if necessary, use glue for a tighter fit since they must rotate in tandem seamlessly. Then slide part 5 through the hole in part 4 before carefully pressing it into part 1 while ensuring all components are correctly oriented. After this, slide part 2 over part 3, then secure part 4 to part 2 by gluing it onto a specially designed ridge – patience may be required here for a snug fit. Finish by sliding part 6 over part 2 and glueing it firmly to part 4 as well. Alternatively, you could also opt to glue the top edge of part 6 directly to part 2. To conclude, insert part 8 through the hole in part 7 with ease. Next, take part 5 gently but firmly and place it over part 7 – a perfect bond can now be secured by gentle pressure and an extra bit of adhesive might also do wonders for your parts sticking well together in all ways necessary.
