Smart Vapor Smoothing

Automated post-processing

Zortrax Apoller is a desktop smart vapor smoothing device offering industrial class performance. Every aspect of a smoothing process is managed by proprietary algorithms to get the looks of FDM 3D printed models on par with injection molded items.

Speed and ease of use

Fully automated smoothing process is easy to set up and takes about 3h.

SVS technology

SVS is a proprietary Zortrax technology for automated vapor smoothing.

Consistent quality

Models are evenly smoothed every time, regardless of their size and geometry.

Certified safety

The Apoller has an EU ATEX certificate of safety.

Wide compatibility

Acetone and MEK are supported to smooth models made on all FDM/FFF 3D printers with ABS, HIPS or ASA-based filaments.

How proprietary SVS technology removes visible layering

Smart Vapor Smoothing (SVS) technology evenly smooths surfaces on all kinds of models, including those with complex geometries and interlocked movable parts. It's done through automatic management of temperature, pressure, and concentration of solvent's vapors in the Apoller's smoothing chamber.

Compatible with all FDM/FFF 3D printers

Zortrax Apoller can smooth models printed on all FDM, FFF, LPD, and LPD Plus 3D printers. The device is compatible with filaments based on ABS, HIPS, and ASA, regardless of their manufacturer. Just remember to use only pure acetone or pure MEK as solvents.

A flexible manufacturing plant

3D printing farms can cost-efficiently deal with low to medium scale production by moving it in-house and making on-the-fly adjustments possible. Complemented by Apoller post-processing devices, they can now offer products' quality on par with injection molding.

Solving the low-scale production

Contracting external suppliers, almost no room for adjustments, and high cost per unit are among major issues with low-scale production because the economy of scale is not yet there to bring the prices down. Once significant resources are invested in making injection molds for a new product, a business is basically all-in.

Smart Vapor Smoothing

Automated vapor smoothing is simple and safe enough to be performed by untrained staff.

Step 1 Print

Print the models on any FDM, FFF, or LPD 3D printer.

Step 2 Smooth

Place the models in the chamber, close the door, and choose the smoothing settings on a touch screen.

Step 3 Enjoy

The Apoller does all the rest on its own. After 3h models are smoothed and ready to use.

Vacuum system

The vacuum system in Zortrax Apoller prevents the pressure inside the smoothing chamber from getting higher than the pressure outside of it even after the solvent has been vaporized. That's why the vapors are kept inside the chamber instead of being pushed out of it.

Advanced vapors' circulation
and condensation system

The vapors in the Zortrax Apoller smoothing chamber ar circulated upward to evenly cover the models. Fragile and intricate details are covered with less solvent to keep their shape intact. Once it's done, the condensation system retrieves the excessive solvent that can be reused.

Advanced safety system

Due to redundancy carefully engineered into the system, Zortrax Apoller offers industrial-class reliability. The device is double sealed off from the environment. At all times the pressure inside the smoothing chamber is kept below the pressure in the room. Besides double seals, this is yet another level of redundancy in the safety system preventing fumes from getting out of the smoothing chamber. It also keeps the chamber closed even when there is a power outage causing its electromagnetic lock to shut down. When the power backs on, Zortrax Apoller automatically decontaminates the chamber before allowing anyone to open it.

ATEX Certification

Safety systems are certified to meet high standards required by the ATEX 2014/34/EU Directive regulating the equipment intended for explosive atmospheres.

Every unit requires an annual inspection conducted at Zortrax HQ to keep the EU ATEX certification valid and ensure safe operation of the device.
