Chipping
Chipping
Bits of part break off during removal from platform.
How to Identify
Chipping can be diagnosed as follows:
- Damaged area occurs where the part contacted the platform.
- Occurs on rigid resins.
Cause - Inconclusive

Troubleshooting
It is recommended that you review all the possible solutions before taking action to ensure you are pursuing the best course of action.
If the best course of action is not apparent, try the troubleshooting options in the order listed. Refer here for more tips.
Process and Hardware Checks
If any of these conditions apply to your print, take the corrective action and reprint to see if the problem is resolved.
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.
If problems persist, please reach out to Carbon Support.
Explanation & Causes
Explanation
- Part may be strongly adhered to the platform. Reference also Over-Adhesion
- Poor removal technique.
- Using scraper to pry part off platform.
- Not keeping scraper in contact with platform during removal.
- Using too much force with deadblow hammer.
- EPX is more susceptible to chipping due to brittleness.
Causes
Post-Processing
How the part is handled in post-processing is causing the defect.
Root Issue | Problem | Why Defect Presents |
|---|---|---|
Platform Removal | Aggressive | Resins are delicate in the green state and require gentle handling. |
Print Preparation or Part Design
How the part is oriented, supported, or designed is causing the defect.
Root Issue | Problem | Why Defect Presents |
|---|---|---|
Over-adhesion | Large cross section on the platform | More surface area to adhere the part to the platform at the higher base exposure levels. |
Hardware
The printer, cassette, or platform is dirty or requires maintenance to resolve the defect.
Occasionally, a defect may indicate the printer requires servicing by a Carbon engineer.
Root Issue | Problem | Why Defect Presents |
|---|---|---|
Cleaning | Factory coating on platform | The factory coating on a new platform can lead to stronger adhesion. |
Print Plan Adjustments
Print Plan Adjustments adjust the print plan to optimize mid to high volume production and/or address part defects.
In doing so, adjustment may both prevent or cause defects. Below are adjustments that can cause this defect.
Printing Stage | Parameter Type | Type of Adjustment | Why Defect Presents |
|---|---|---|---|
5 Exposure | Exposure Timing | Increase | Adhesion is increased with more UV exposure |
5 Exposure | Brightlining | Increase | Adhesion is increased with more UV exposure |
