3D modelling and mechanical design
the mechanical properties values will be used to find the proper material and 3D printing process, after identifying the best process and material , a FEA simulation is required to be performed to check if the material and process were chosen are selected correctly and can withstand the actual forces and load applied on the product ...

To convert a wheelbarrow into drain silt carrier
We use wheel barrow to carry any solid item like construction material etc. . We need to convert it into a caarier of drain waste by adding fileration and small water storage. Idea is that during cleaning of open drain in small colony / gali , we dont have any carrier which can carry drain silt which is mixed with water therfore we had to kept it on the road and for drying. A wheelbarrow may be changed in acarrier which can drain the excess water and only solid waste remain in the carrier.
Compressor Valve Improvement
I have several designs for a compressor valve that I have been working on. I am looking now to manufacture based on a numnber of tests made. However, I have 2 designs that I need to decide to finalize. I would like to get good engineering feedback on the best option that will ensure no leakage and the longest operational running hours. These valves will run in a compressor and need to run for 16000hrs and longer.
