CLEARANCE — Phrozen Sonic Mega 8K V1 — $1,999

This is the Phrozen Sonic Mega 8K V1, not the V2. The V1 does not include a built-in air filter, does not support the pump and fully automatic resin feeder, and does not have the built-in hanger for suspending the build plate while resin drips into the vat.

But you pay only $1,999 for the same build volume instead of the current MSRP of $2,899–$3,199 advertised by Phrozen.

Condition: Refurbished, nearly mint condition. This unit was sitting in our warehouse since early 2025 and was not sold because it was mislabeled as the Phrozen Cure Mega station instead of the Phrozen Sonic Mega 8K V1 3D printer.

Our technical support inspected the machine and confirmed it is fully functional. Read their report and see photos here: Google Drive photo gallery

What maintenance does the Phrozen Sonic MEGA 8K require?

The Phrozen Sonic MEGA 8K requires 8+ maintenance procedures to ensure reliability, prevent failures, and maintain print quality.

After Each Print Session

• Vat Cleaning Function: Use the built-in vat cleaning feature with 20-second exposure time to cure residual resin in the vat when planning to use the same resin for subsequent prints. This prevents cured resin accumulation that leads to FEP film damage.
• Building Plate Cleaning: Clean the perforated aluminum building plate with paper towels, then immerse in 95% isopropyl alcohol for 15 minutes to 1 hour to remove all cured resin from the holes.
• Resin Filtration: Pour leftover resin through filters to remove cured particles before storage, preventing FEP film breakage during future printing operations.

Weekly Maintenance

• LCD Screen Cleaning: Perform dry cleaning with microfiber cloth or wet cleaning using 95% sanitizing alcohol applied with soft paper towels in one direction to remove dust, smudges, and fingerprints.
• Resin Vat Deep Cleaning: Remove and disassemble the aluminum resin vat, cleaning all components with 95% isopropyl alcohol to remove residual resin from metal frame junctions.

Monthly Maintenance

• Z-Axis Ball Screw Lubrication: Clean the dual linear rail system with lint-free wipes, then apply lithium-based lubricant such as Shell Alvania Grease S or REACH_151 EP Lithium Grease to the ball screw mechanism. This procedure prevents friction buildup and maintains 0.00125mm positioning accuracy.

Quarterly Maintenance (Every 3 Months)

• Z-Axis System Inspection: Test Z-axis movement from bottom to top, checking for unusual sounds or vibrations during operation. Perform complete dry cleaning and re-lubrication of the ball screw assembly.

As-Needed Maintenance

• FEP/PFA Film Replacement: Replace the PFA (nFEP) film when dented, deformed, or pierced using the diagonal tightening sequence for proper installation. The replacement process requires 8 corner screws, 4 side screws, and remaining screws tightened diagonally.
• LCD Screen Resin Spill Cleaning: For resin spillage, cover affected areas with 95% alcohol-soaked paper towels for 12-24 hours under plastic wrap, then remove softened resin without metal tools to prevent LCD damage.
