The Building Blocks of VVD Technology

Welcome to the first in our four-part series guiding you through a deep dive into the building blocks of our first-of-their-kind automated support and resin removal and surface finishing solutions 3D post-print technologies. You may know us as the world’s first and only software-driven solution for post-processing of additively manufactured parts for all 3D print technologies. What you may not know is that we have four unique key technologies that harness various chemical and mechanical energy sources that form the basis of all the innovative solutions we offer.

Our four core technologies are:

  • Volumetric Velocity Dispersion (for soluble support and resin removal)
  • Submersed Vortex Cavitation (for soluble support and resin removal)
  • Suspended Rotational Force (for surface finishing)
  • Thermal Atomized Fusillade (for excess powder removal and surface finishing)
PostProcess DECI™ using VVD Technology

In a series of four blog posts, we’ll educate you on the building blocks of each technology and relate them to the flashy words our technologies are tagged with. First up is our Volumetric Velocity Dispersion (VVD) technology for support and resin removal, which is used in our DECI and BASE Solutions.

The key components to VVD are our:

  • Proprietary detergents
  • Two jet rack manifolds
  • AUTOMAT3D™ software

Now let’s dive into the role each one of these components plays…

 

Proprietary Detergents:

Our additive-formulated chemistry is leading the charge, playing a key role in the power of our VVD technology. Unlike anyone else in the industry, our three primary detergents for use in the VVD line were all developed by our chemists specifically for additive materials. We have a detergent specific for each of the primary polymer based print technologies – material extrusion (i.e., FDM), material jetting (i.e., PolyJet), and vat polymerization (i.e., SLA). For each one of these technologies, PostProcess’ detergent will dissolve the soluble support material or uncured resin without compromising the build material. Our chemistry is optimized for the materials used by each technology, and then taken a step further and optimized by multiple fine-tuned mechanical energy sources which we will cover in the next section.

The parts being doused in a high volume of our proprietary detergent while processing covers the “Volumetric” portion of VVD technology.

 

VVD TechnologyTwo Jet Rack Manifolds:

Leveraging spray technology rather than submersion introduces a mechanical energy source that is very unique in the industry. PostProcess VVD technology utilizes two jet rack manifolds, the first being a stationary bottom mounted manifold intended for low pressure, full tray coverage. The second, top mounted manifold moves on a linear axis across the length of the chamber. The user may set parameters for varying levels of energy output from the jets via the AUTOMAT3D software for a more focused agitation. Together the two opposing jet streams keep the parts in equilibrium throughout the cycle mitigating the need for fixturing. The mechanical energy from these two streams, flowing at rates upwards of 200 GPM (over 750 liters/minute), optimizes the chemistry by disposing of the support material as it weakens, dramatically accelerating the cycle times. This high volume flow complemented by low pressures (less than 35 PSI, or 241 kPA) remains gentle on part geometries throughout processing. These powerful yet gentle flow patterns are what accounts for the “Velocity” component in our VVD technology.

 

AUTOMAT3D Software:

At this point, we have covered the hardware and chemistry portion of PostProcess’ VVD technology. Our AUTOMAT3D software is the final and most imperative part of our technology. The acute control of the system’s energy sources is essential to all of our solutions. AUTOMAT3D acts as the conductor of the whole process, configuring all of the energy output sources in response to sensor input data. The software manages the temperature, pH, jet flow patterns, and movement, all in concert with cycle time. This control over the combination of jet usage and movement is the “Dispersion” piece of the technology. Not only does the software provide the solution with the highest degree of energy management, but it also simplifies machine operation for the user. With recipe storage, process parameters can easily be saved for easy recall, requiring minimal operator time and promoting consistency with each cycle. Lastly, preventative maintenance and warnings allow users to plan for maintenance, further minimizing any downtime.

Now that you have a better understanding of our Volumetric Velocity Dispersion technology, find out if it is right for your application! Contact us today to discuss your specific application and get the benchmark process started.

New White Paper: Considerations for Optimizing Surface Finishing of 3D Printed Inconel 718

DMLS Metal PrintingMetal and metal alloy parts can now be made with near limitless design freedom to high standards using a wide range of metal powders via additive manufacturing (AM). And while prototyping metals with 3D printed technologies has proven quite valuable, it is no longer solely for design validation. It is now being used for the production of components for the most demanding applications in aerospace, automotive, medical, dental, and industrial industries.

This added value does not come without its challenges, however. Many of these challenges appear in the post-print stage after the geometry has been generated in achieving an acceptable finish on the part.

Our latest white paper discussions a novel approach to smoothing the surface profile for one particular metal produced by AM, nickel superalloy Inconel 718. Key considerations reviewed in this paper include part density and hardness, corrosion (chemical) resistance, grain structure, as well as manufacturing factors including the impact of print technology and print orientation on surface profile outcome.

Learn about how combining software-driven automation and a patent-pending chemistry solution dramatically improves surface finish results including reduced technician touch time and increased consistency and productivity.

Printing PolyJet? Your Guide to the Benefits of Automation Utilizing SVC Technology

Printing PolyJetIn our latest White Paper, we’re tackling the dilemma of how to achieve increased productivity and consistency for the tedious task of PolyJet support removal.  Whether printing with SUP705 or SUP706, each presents their own challenges. The SUP705 material adheres to the part more firmly, so when applying intense force with legacy methods such as water blasting, you can easily damage fragile portions of a print. With SUP706, as it is a softer support material, you run the risk of being overly aggressive and damaging the print with manual methods.

This new White Paper includes results from testing of both SUP705 and SUP706 PolyJet parts in our software-driven DEMI Support Removal solution, demonstrating how SVC technology can minimize touch time, breakage, and the learning curve of automation to advance your additive manufacturing operation.
