Overview🔗

Warning

Resin printers are TA-operated only and part of a paid print service. Unauthorized use of TA-only printers may result in suspension from all TTDA resources.

Health and Safety🔗


Eye protection is provided for your safety and must be worn
Gloves must be worn
 

Resin may cause allergic reaction
Risk of fire*
 

* Improper handling of IPA may cause combustion

Warning

Resin materials are potentially hazardous. Please follow the safety guidelines below:
- Turn on the exhaust system (shared with the laser cutter) when the printer is in use.
- Always wear nitrile gloves and safety goggles when operating or cleaning the resin printer.
- Avoid direct skin contact with resin. If contact occurs, immediately rinse with plenty of water and clean with alcohol.
- Do not pour uncured resin into sinks or drains. Dispose of it properly according to lab regulations.
- Use alcohol (isopropyl alcohol, IPA) to clean tools and parts, and avoid inhaling its fumes.
- All waste materials (including used paper towels, gloves, etc.) must be discarded in the designated chemical waste bin. - Keep the printer lid closed if not accessing anything inside the printer.

Only the machine exhaust (left knob) must be active during printing; if fumes are strong, also enable the room exhaust (right knob).

Laser Exhaust

When using the machine exhaust, open the inline flap by one quarter. The flap is normally closed to keep laser‑cutting dust from entering the printer.

Available Machines🔗

Machine Count Build Volume (mm) Filament
Saturn 4 Ultra 1 218 x 122 x220 (10") Resin
Sonic Mega 8K S 1 330 x 185 x 300 (15") Resin

Chitubox and SatelLite print profiles are available for download

Solid Model🔗

Models must be watertight solid objects with actual thickness (i.e., not surface-only geometry).

Print Resolutions:

XY resolution Z resolution
≥0.05mm (min)
≥0.1mm (recommended)		 ≥0.025mm (min)
≥0.1mm (recommended)

Chitubox🔗

Chitubox is the most mature and widely used slicing software for resin printers. It offers a free version, which is officially supported by the atelier.

Presets🔗

Official print profiles are available here. Once imported, presets labeled with TTDA will be accessible. These serve as reliable starting points for most prints.

Parameters🔗

Certain parameters may require fine-tuning depending on the condition of your FEP film and resin used to ensure successful prints.

Exposure Time🔗

  • Standard Exposure Time: 2.5 seconds is a typical minimum for most resins.

    • If the print does not form properly or there is a clean break with both sides printing cleanly, increase the exposure time in 0.25-second increments.
    • If the print shows excessive blobs or loss of detail, decrease exposure time in 0.25-second increments.

  • Bottom Exposure Time: 35 seconds is generally sufficient for stable adhesion to the build plate.

    • If the base adheres too strongly, decrease bottom exposure in 0.5-second increments.
    • If the base fails to stick, increase bottom exposure in 0.5-second increments.

Note

If the resin manufacturer's recommended exposure times differ significantly, follow their guidance.
However, if the recommended values deviate from the atelier's defaults by no more than ±0.3 seconds for normal exposure and ±3 seconds for bottom exposure, the atelier's starting values (2.5s normal / 35s bottom) are likely acceptable for initial testing.

Lift Distance🔗

Info

The Saturn 4 Ultra uses a tilting mechanism managed by the printer firmware. Therefore, lift distances will not be shown when S4U is selected as the printer.

If your print breaks/tears mid-way, add 1mm to all lift distances.

Note

  • If the model (excluding supports) fails to form at all, adjust the Exposure Time, not the lift distances.
  • Retract Distance is automatically calculated and typically does not need modification.
  • Lift and Retract Speeds generally do not require changes. Prioritize adjusting Exposure Time if issues persist.

SatelLite🔗

SatelLite is a new and promising slicing software for resin printers. The atelier is currently evaluating and testing it. Official support may shift to SatelLite in the future based on ongoing results.

Presets🔗

Preset profiles are available here. Once imported, presets labeled with TTDA will appear. These are recommended as reliable starting configurations.

Parameters🔗

Certain settings may need adjustment depending on the condition of the FEP film and resin used to ensure consistent print success.

Exposure Time🔗

  • Normal Layers Exposure Time: 2.5 seconds is a common minimum for most resins.

    • If the print does not form properly or there is a clean break with both sides printing cleanly, increase the exposure time in 0.1-second increments.
    • If prints show blobbing or a loss of detail, decrease the value in 0.1-second increments.

  • Bottom Exposure Time: 35 seconds is typically sufficient for reliable plate adhesion.

    • If the model adheres too strongly, decrease in 0.1-second increments.
    • If the base detaches during printing, increase in 0.1-second increments.

Note

If the resin manufacturer's exposure recommendations differ significantly, follow those values.
If the difference is within ±0.3 seconds (normal exposure) and ±3 seconds (bottom exposure), the atelier’s default values (2.5s / 35s) are acceptable starting points.

Lift Distance🔗

Info

The Saturn 4 Ultra uses a firmware-controlled tilting mechanism. As a result, lift distances will not be shown when S4U is selected as the printer.

If your print breaks/tears mid-way, add 1mm to all lift distances.

Note

  • If the main model (excluding supports) fails to form, adjust the Exposure Time, not the Lift Distance.
  • Retract Distance is calculated automatically and typically does not require changes.
  • Lift and Retract Speeds usually do not need adjustment. Focus on tuning Exposure Time if issues persist.
