PostProcess Technologies' Submersed Vortex Cavitation (SVC) technology is already integrated in the DEMI 400 version to ensure a uniform cleaning effect.

The DEMI 400 provides a precise, automated post-process solution for additive manufacturing operations.

A uniquely,e software-controlled process control in conjunction with special cleaning agents, ensures highly efficient cleaning of components.

Technical data:

Basin size: 355 x 355 x 355 mm.

Capacity for consumables: 64 liters

Variable temperature: 30-63°C


Vortex Pumping System

PostProcess SVC solutions use a sophisticated pumping system to rotate the part while it is immersed in the cleaning agent. The vortex component of SVC technology ensures that the part is uniformly exposed to the cleaning agent and cavitation from the ultrasound, regardless of density or geometry and its effect on the buoyancy of the part.

Variable ultrasound

PostProcess uses cavitation generated by ultrasound as an additional source of mechanical energy to improve cleaning. The ultrasound creates compression and expansion waves in the cleaning fluid by emitting sound waves with varying frequencies and amplitudes. On the surface of the part, the movement of the liquid causes cavitation and the formation of small bubbles. As the substrate is weakened by the chemical, these bubbles agitate it, accelerating the reaction.

Advanced cleaning agents

Post Process' unique chemistry is a key factor in the effectiveness of SVC technology.

The three main cleaning agents in the SVC line were all developed by Ph.D. chemists specifically for cleaning additive materials.

Here, each printing process has its own special cleaning agents, which have been optimized for the materials used.

PostProcess cleaning solutions dissolve the substrate or uncured resin for each of these technologies without damaging the build material.


Optimal wave generation

In a conventional system, the carrier material disintegrates and falls to the bottom of the machine. The efficiency of the shaft generated by the converter would then be compromised by this deposited material. By placing them on the side of the machine, PostProcess SVC machines have reduced this problem and ensured optimal efficiency throughout the cycle.

Software-controlled cleaning algorithm

The purging algorithm, which carefully controls the energy, speed and direction of the system, ensures that the cleaning time is minimized.

The AUTOMAT3D software varies the rinsing intensity, temperature and process time to achieve ideal cleaning in the shortest possible time.
