First print with 3Dresyns® resins
This page helps users move from product selection to a first controlled print using the correct 3Dresyns® workflow.
Purpose: reduce confusion, avoid unnecessary trial and error and guide the user from starting parameters to first validation.
A correct first print should connect material selection, IFU guidance, software parameter entry, calibration print validation and post-processing control.
1) What a first print should achieve
Start with stability, not with aggressive optimisation
A successful first print should confirm that the selected resin, printer and workflow can produce a stable result under qualified starting conditions.
- correct adhesion to the build platform,
- sufficient green strength,
- basic feature reproduction,
- predictable support behaviour,
- clean washing and drying route,
- controlled post-curing route.
2) Recommended first-print workflow
Use the workflow in the correct order
- Select the correct resin family for the intended application.
- Read the relevant Fast IFU and IFU.
- Enter the qualified starting parameters in the slicer.
- Use moderate and stable lift settings for the first trial.
- Print 3Dtest1 first.
- If successful, continue with 3Dtest2.
- Only after this initial success, move to deeper CRT-based optimisation if needed.
3) What to print first
Use low-risk validation geometries before real parts
The first print should not be a complex final-use geometry. It should be a controlled validation print.
Start with 3Dtest1
3Dtest1 helps verify general printability, XY detail and whether the selected standard exposure is in a reasonable working window.
Then move to 3Dtest2
3Dtest2 helps evaluate supports, XYZ printability and Z-axis response after the first flat print has succeeded.
4) What to keep simple on day one
Do not over-edit the profile too early
For the first print, focus mainly on:
- layer height,
- normal exposure,
- bottom exposure,
- bottom layer count,
- lift distance and lift speed.
Keep secondary or advanced settings stable unless there is a clear reason to change them.
If the first print fails, do not change many variables at once. Correct the most important variable first, then test again.
5) What to check after printing
Evaluate the print before chasing more optimisation
- did it adhere correctly,
- is it too soft or too brittle,
- are the features readable,
- are supports behaving correctly,
- is the geometry stable after washing.
- was the resin mixed correctly,
- was the vat clean,
- was the part fully dried before cure,
- was the post-curing route appropriate,
- was the selected geometry suitable for a first test.
6) What to do if the first print fails
Use quick diagnosis first
- Detaches from platform: review bottom exposure and bottom layers.
- Too soft or weak: review normal exposure.
- Too brittle or too stuck to the release film: review over-curing.
- Poor detail: review unnecessary overexposure.
- Previously stable, now inconsistent: review UV power, temperature and resin condition.
Governing principle
A good first print is a controlled first validation step, not a final optimised process.
