I have started 3D scanning, 3D modeling and 3D printing my custom model kits.
I had created masters, poured molds and urethane resin casted a correction set for the Kitty Hawk Banshee. There are issues with expansion, contraction, degrading and storage of the molds. Plus, the labor and expense of having to make more molds when they deteriorate. The molds only last for so many castings. There is also the need to vacuum the molds before curing and pressure casting the resin parts.
With 3D modeling, the parts can be tweaked over and over until the correct shape is achieved. the 3D scanning allows for the designed parts to
3D printing is the way to go. Once the 3D modeling is done and made into STL files, it is just a matter of loading the file into the 3D printer and pressing the start button. A few hours later and the parts are done.
I have been learning the new tech needed for this process and although I miss the custom hand crafting, this is the best and most efficient way to mke the models.
