Outer wall speed	30	Support speed	60
Support place	everywhere	Over hang angle	50
Build plate adhesive type	Raft	Raft extra margin	15mm

1. Remove support

Prints with support material will require post-processing to remove the support structures. This can be achieved by breaking the support structures from the build material.

• Tear the inner support structure

Start by removing the walls of the support structure with gripping pliers. This allows you to quickly tear away the majority of the inner support structure.

• Pull the Breakaway support from the build material

After removing most of the support structure, the remaining part(s) can be pulled from the build material. Use cutting pliers to grab the Breakaway support in a corner and try to carefully get underneath it, then bend it upwards. Repeat this for several corners, so that you can loosen the support from the model around the corners. After this, pull the Breakaway support from the model.

• Peel the last traces from the model

Sometimes a final layer of the support material will remain after pulling the Breakaway support from the build material. If this happens, use cutting pliers to peel it off from a loose edge. Any leftover traces on the model can be removed with tweezers.

2. Polish model

We would use sandpaper to polish model with water ,choice sandpaper 180 for rough polish, 240 for polish and 320 for finish polish The following is the result

3. Painting

polish,painting and assemble for the final prototype.

4. Varnish(from translucent to transparent )

This method need use professional Polish mehtod （sandpaper polish at least P800 ）and then varnish.
