SLA/DLP/LCD 3D Printing Troubleshooting
Here! That's why we want to make this page for SLA/DLP/LCD 3D printing troubleshooting.
Sticking to FEP Vat
If there are no parts or just fragmentary ones on the build platform, you should check your issues before restarting.
Unexplained Thin Layers Sticking to FEP Vat
Unexplained thin layers sticking to FEP vat and located in the same position each time.
Pits and Holes on the Surface
Shallow pits and the deep hole are caused by different factors, which need to be distinguished.
Hollowed Part Being Broken After A Period of Time
For some hollowed parts, after putting for a period of time, it may be cracked or even broken.
Broken Layers or Bulging Bubbles
Parts of the finished prints may appear to have broken layers bubbles filled with uncured liquid resin.
Layer Separation
Layers are separated into layer by layer which should be originally compacted together.
Misrun
Misrun means that the part has been printed but incomplete.
Floccules
Floccules are usually suspended in liquid resin, or the flakes or flocculents attached to the part or the surface of support structures.
Uncured Resin on the Part Surface
Sometimes, the surface of the part looks as being covered with a thin film which is in a state of semi-curing.
Separation of Supports and Part
Separation of supports and part is mainly caused by the peel force/separation force during mold release from FEP.
Broken or Layer-separated Bridges
A bridge generally refers to a horizontal overhang that connects two ends of a part, such as the middle part of the symbol ∏.
How Angles of Models Affect Surface Quality
In light-curing 3D printing, the placement angle of the model has a great influence on the printed surface.
