This is a technique which I haven’t heard talked about too much. Most clearcoats contain acetone. By clear coating an ABS print, it does an amazing job smoothing and sealing the object. It also removes any sanding residue, and any marks from ABS Slurry!

This video show us how to use the liquid silicone rubber to make mould by pouring way.
A. The operation of pouring way
Pouring way is suit for the product with the smooth surface and simple pattern, no need mold line. The soft silicone rubber will be choose for pouring operation, easy operation and demould, won’t destroy the original mold.
Step 1 Handle the original mold
Choose a prefect original mold, Manually polish and smooth the model, clean the surface and dry it. Fixed the original mold in a smooth wooden board, and using 4 pieces wooden board around it to make a square frame
Brushing the release agent evenly on the surface of original mold and wooden board.
4 kinds release agent we often used in condensation silicone mold: Vaseline, soap water, detergent, liquid paraffin.(silicone oil also can be used as release agent)
Step 2 Weight part A & part B according to the mix ratio recommended
Weighting two parts in Electronic scale with mix ratio 100:2 or 100:5.
Eg: Take 100g part A and 2g part B
Step 3 Stirring evenly
Remember to mix part A and part B evenly, otherwise the silicon rubber will be partly solidified and bring problems in your final operation. What’s more, the finished molds will meet a short life. All of these will cause a waste of silicon rubber.
Step 4 Vacuum pumping
For releasing the air bubbles, after mixing evenly, put the mixture in to vacuum pumping for 3-5 minutes, without exception, this step takes less than 10 minutes. Otherwise, it will cause cross linking reaction, and no more further steps will be available.
Step 5 Pouring
Pouring the silicone rubber to the frame from a corner, make the silicone rubber flow to the frame smooth.
Step 6 demoulding
After 3-5 hours later, can demould the silicone mold, It’s will be better for mold to demould after 24 hours
