Disclaimer: This is my first post on this forum so my apologies if I do anything incorrect. You may have also seen me on DiecastAircraftForum but I have moved my thread over to Wings900 as I tend to use it more.
Anyways, I have recently bought some 3D Printed GSE off Shapeways but they are quite expensive and I do not like Herpa or Gemini GSE. I decided to solve this problem by creating my silicone caulk mould that replicated the GSE I bought off Shapeways. After that I would inject hot glue into the mould and hopefully have an exact replica of the GSE. Nothing went as planned...the shape of the GSE only barely replicated the original and I soon realised it was because the mould's shape was incorrect and due to hot glue's temperatures air bubbles have been forming on the object. This silicone mould was homemade with potato starch and silicone caulk mixed into a non sticky putty that I was able to wrap around my object to form a mirrored design into the putty.
Here are some photos of the unsuccessful hot glue gse outcome:
Update: First time unsuccessful due to resin not filling mold cavity but second time more successful though front air bubble needs to be filled.
In conclusion please feel free to reply with some feedback or criticism if you like as it will help me not mess up on my castings. I will also soon spray a coat of white matte primer over the castings and then stick waterslide decals onto the finished castings to hopefully reveal a high quality resin model.
