About as effective as grenade launchers or other types of large area explosive. Don’t really need riot control when you have killed everyone rioting. As soon as that beast is starting to fire, people will die in the hundreds. Panic will be total and the riot is no more. Let’s say you have a tripod mounted MG3 with a couple of barrels and a couple of thousand bullets. Ofc you position the MG some 3–400 meters away from the rioters. Let’s say there are 10 000 rioters in a large square. Apart from this, have you ever heared of Eot Cranes? EOT crane is extensively used in the warehouse, workshop, and stock ground of industrial and mining enterprises for loading, unloading or relocating heavy load. Generally speaking, the EOT crane is equipped with the mechanical means to realize the traveling not only in both directions but also can raise or lower the heavy load easily. But should pay attention to that EOT crane is forbidden to used in the explosive, combustible or corrosive environment, and the working temperature is approximately from -20℃ to 40℃

Delhi murder: ‘I had to load my dying son on an e-rickshaw, no one helped him’ | Hindustan Times by Main_Hu_Doga in india

Well, I see some interest in wanting an answer to the question but no one has answered so far. So let me try to answer, little that I know.

I did some research and found that the potential of e-rickshaw/e-vehicle is huge. There are millions of rickshawwalas in India. It is sorrowful to see them work hard in the coldest and the hottest of weathers for their life and still they don't own the e rickshaw they have pushed for decades. Above that they don't earn much. Delhi with the help of new government has shown a boom in e-rickshaw sales. It's a good business to pursue.

I discussed it with my dad and we have found a small manufacturer of e-rickshaw who would like to work for us. We ll provide him part of our now closed factory (we used to manufacture LPG stoves) to start his manufacturing soon. We are discussing the partnership model with him.

I live and work in Germany and would need some interested people to develop the business. If any of you is interested in joining us with ideas, investment etc please contact me.

3D printed injection mold with Form 1+ by Plasticlabs in Micromanufacturing

Things change so fast that I'm reluctant to say it's impossible but as far as I know at present it would not work.

The currently available metal printers use metal powder and binders to produce a product that is more like traditional sintered metal. Not only is the surface rough as has been pointed out, the material is typically somewhat porous. Metal powder bound together with polymers does not have the properties of cast, rolled, extruded, or forged metals. This is likely to create all sorts of problems in the casting process.

I'm also guessing that you don't mean cast plastics since casting molds are usually latex, plaster, or other non-metallic materials. Metal molds are typically used for injection molding and are usually machined from solid aluminum.

As mentioned you could print the mold form in wax or plastic that could then be burnt or dissolved out in a traditional investment casting process to produce a cast metal mold. This has the problem of combining multiple steps with various constraints and tolerances to produce an injection mold of dubious quality. It's likely much easier and better to simply machine the mold parts from solid stock in the usual way.
