How To Make a Giant LED • How an LED Works

3d files: AMZN RESIN: AMZN LED Hi folks, in this video, I’m going to experiment different methods to cast epoxy resin instead of using classic silicone molds. I’m going to try to use wax paraffin or in any case try to use their 3-D printer casting it’s self for Apoxsee resin inside. First of all I design into fusion 360 the file I need to have the mold and the shape of an LED a pretty huge one and afterwords I try to print it she can use any kind of 3-D printer for these purpose but in my shop, I have a racing 3-D printer, which is great to have perfectly smooth design objects After printing. Hi soon realize I have the mold that isn’t perfect. It’s all covered with square faces, which is a bad thing because we never seen his LED with the square faces to fix it. I mounted everything in elite and use a lot of sandpaper to make everything smooth again now that everything is shiny smooth I can then take a spray and apply it this patch layer that helps to release the mold. In this case it didn’t work well. It could be a great idea to use some wax or some oil as a layer for let the resident not stick to the mall to self. After pouring the resin inside and mixing everything in a glass container, I can see I have so many air bubbles and that transparency of the Apoxsee raising isn’t good enough. I absolutely need to remove all these air bubbles and I can’t use a fridge air compressor to do this. You can use a fridge air compressor is a vacuum pump, just connecting the suction pipe and sucking away all the air now that I have remove all the air bubbles I can forward the Apoxsee resin inside the mold and wait for about 24 hours that everything cures the next morning I just realize that it wasn’t working, unfortunately the Apoxsee resin sticks to the rising of the mold itself, and it’s impossible to remove the two parts, I don’t switch method this time I want to experiment with some paraffin wax. This could work, but you need to choose the right Apoxsee resin. Otherwise it will get so hard and get hot very quickly and come out the wax itself. In this case I was so lucky that the room temperature and the humidity Wass Perfect and the Apoxsee resin took so much time and didn’t get so hot and didn’t deform the mold itself after this time I can then break open the paraffin, wax, mold and take away the LED. It’s perfectly shiny and smooth, and I Duncan connect power 12 V to the LED chip and that’s it. My LED is ready I’m pretty sure you can take inspiration from these procedures for your own epoxy creation. I’m here just to give you an inspiration, but it’s up to you to make yourself what you really need.
