Veining

11min

Veining
Organic ridges on part in the build direction.
﻿
How to Identify
Veining can be diagnosed as follows:
Ridges on part along the build direction (Z axis). 
Can be wandering or straight.
May be wavy especially for larger, flat surfaces.
This is an uncommon defect.
An extreme form of this defect is called Caping﻿﻿
Cause - Inconclusive 
Cause - Inconclusive
 
﻿
Cause - Supports too close to surface

Troubleshooting
﻿
Print Preparation or Part Design Adjustments
The following solutions will address print or part-related causes of the defects. Choose among the suggested actions below and select the best approach for your application. Usually only one type of adjustment is needed.
Adjust supports to allow more space between part and support.
Adjust density of supports to allow for more resin flow
﻿
Increase padding to at least 5 mm.
Reference Layout﻿﻿
﻿
﻿
Reference Print Plan Adjustments﻿ for guidance on the following parameters:
4 Settle Down Stage
Delay Timing Parameters
Minimum Pre-Exposure Delay
Minimum Time Force Slope Down Settled
If problems persist, please reach out to Carbon Support.
Explanation & Causes
Explanation
Parts, features and/or supports are too close together restricting resin flow.
Slow moving resin heats up making it more susceptible to curing from stray UV light.
This condition is magnified over time as resin heats up over the course of the build.
Supports are too close to surface

Root Issue
Problem
Why Defect Presents
Supports
Over-supported
Parts that are over-supported provide less space for resin to flow properly throughout the build causing light to scatter.
Layout
Parts too dense on platform
Padding between parts is to small for resin to flow properly throughout the build causing light to scatter.
Print Profile
Print too fast in Dynamic
A shortened print gives less time for resin flow to all areas of the build causing light to scatter. For M1 and M2 printers
