Smile Custom Resin and Hot Glue 1:400 GSE

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:

Resin GSE:

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.

Awesome work my friend. Do you plan on selling these? I know a few people who would be interested, as the shapeways prices are too high for what you get!

Re: Custom Resin and Hot Glue 1:400 GSE

Thanks for the reply Callum, unfortunately the likely chances are I would not be selling them as my molds can only produce 20 until they loose detail and I am almost running out of enough liquid silicone for the molds.

Re: Custom Resin and Hot Glue 1:400 GSE

Hello, I did quite the same with a poor result for my GSE. In fact, I bought an already done mold, from an old collector who decided to stop the hobby. I still have some trucks made with the mold but they are not good.
Then, one year ago, I made my own mold of an ATR 72 Herpa, casting it with metal. You can see the "ATR project" thread in the custom section. I will soon (during september/october) make another replica, this time with a 3D plane.

Nice to see people trying to make casting mold too, good luck ! Your result is great !

Re: Custom Resin and Hot Glue 1:400 GSE

Progress update:
Sorry for not posting as usually as I promised as this is all due to me being quite busy lately. I have primed all 15 of my first batch of buses with Rustoleum flat white primer and so far the results aren't the best. The surface is rough and dusty and which I have come to result that my technique for spraying wasn't that good. It was my second time using an aerosol and I realised that the humidity may have also affected the outcome. I will sand each bus (leave some to fill the gaps) and respray them with hopefully better results.
