How to Print Crystal-Clear Models

Why your clear prints look foggy? It's not the resin. It's the post-processing.

Step 1: Print Settings

• Layer height: 0.05mm or lower (finer layers = less sanding)

• Exposure: Use stock settings

• Orientation: Keep clear surfaces support-free

Note: antinky High-Transparency Resin needs zero post-curing. Print → straight to post-processing.

Step 2: Remove Supports

1. Snip large supports, leave 1mm stubs

2. Tweezers for the small stuff

3. Don't pry or yank—you'll scar it

Key: Clean removal = less sanding.

Step 3: Dry Sand (400 → 800 → 1200)

• 400: Flatten support marks + layer lines

• 800: Erase 400-grit scratches

• 1200: Smooth but frosted finish

Pro tip: Wipe dust between grits.

Step 4: Wet Sand (2000)

• Wet sandpaper + damp model

• Light pressure—stop when it feels slick

• You want even, matte, semi-transparent

Tell: Looks like frosted glass when wet? You're done.

Step 5: Clean + Dry

• Rinse with water, wipe dry

• Air dry or cool air

Warning: No alcohol. Turns clear resin white instantly.

Step 6: Clear Coat

This is the magic step.

• Transparent spray (auto clear coat or model paint)

• 15-20cm distance, sweep evenly

• 2-3 thin coats, 10 mins apart

• Switch direction each coat (horizontal → vertical → horizontal)

Why: Fills micro-scratches. Light transmission goes through the roof.

Step 7: Wait 24 Hours

• Room temp, dust-free

• No post-cure needed—just let it sit

• Comes out hard and crystal clear

✅ Remove supports

✅ Dry sand (400→800→1200)
