3D printing model post-processing steps and precautions

3D printing model post-processing steps and precautions!

After the 3D model is completed, the surface is still relatively frizzy. In order to make the model surface smooth, it must be post-processed. What are the post-processing steps and precautions for 3D printing the model? Let's introduce it for everyone.

3D printing

1. Sanding: Sanding can help eliminate the layer lines on the surface of the 3D printed model. At the beginning, use coarser sandpaper, and later use finer sandpaper. And do not operate for too long in the same place to prevent friction and heat generation to melt the surface too much. If the prints need to be glued afterwards, it is best not to rub off the seams too much.


Second, bonding: when bonding, it is best to apply glue in a dotted manner. It is best to allow the two contact surfaces to contact more closely when bonding, such as binding with a rubber band. If the seam is rough or there are gaps, you can use Bondo glue or filler to make it smooth.


3. Coloring: In this step, try to do it in a ventilated and dust-free place, so that the coloring of all surfaces will be uniform. When spraying, you can hang the target, and it is best to keep an arm distance from it. After finishing coloring, you need to wait 1-2 days before polishing.


4. Install screw slot: Install the screw slot can increase the service life of the 3D printing shell. In order to install more firmly, the hole on the model is preferably slightly smaller than the screw slot. Fix the model to ensure stability, and do not operate too fast or too fast Otherwise, the hole may be deformed.


Fifth, silicone mold turning: This process requires a 3D printed mold box, silicone, resin, measuring cup and other objects. If you want to calculate the mold volume, you can first fill the 3D printed mold box with water, and then pour the water into the measuring cup . Through this process, users can easily make multiple copies of a product with materials that cannot be used with 3D printers.
