Thermal - Leveraging heat when necessary to operate in temperature ranges required for optimal Chemical Rate of Removal (cRoR).

Atomized - Balancing and varying both liquid and air pressures to reduce our chemistry to exact particles for precise accuracy while protecting fine feature part detail.

Fusillade - A sequence of controlled jetting, either simultaneously or in rapid succession, to support a variety of geometries and throughput requirements.
SVC - Submersed Vortex Cavitation, utilized in our DEMI Support Removal and Resin Removal family of solutions. A rotating motion helps to dispose of support material while the part is immersed in fluid. This helps provide even exposure to induced mechanical agitation.

Submersed- Part fully immersed and suspended in proprietary PPT detergent.

Vortex - Swirling fluid to create a tumbling effect through strategic pumping scheme.

Cavitation - Formation of vapor bubbles during ultrasonic process creating high-frequency pressure waves to agitate a liquid and break loose from the support material.
VVD - Volumetric Velocity Dispersion, utilized in our Support Removal family of solutions. A series of high volume and flow jet streams spraying bidirectionally, coupled with a perpendicular linear motion for mechanically assisted support removal.

Volume - Detergent is pumped at a rate of 150 GPM.

Velocity - High-speed mRoR to dispose of support material as it weakens.

Dispersion - AUTOMAT3D can control the pressure, spray pattern, and rack travel for targeted agitation.
SRF - Suspended Rotational Force, utilized in our Surface Finish family of solutions. A circulating motion, horizontal or vertical, while immersed in a mixture of composite abrasive and fluid for applying even mechanical force at the surface level.

Suspended - A microscopic layer of detergent creates a film around the media to keep the part suspended.

Rotational - The part cycles during the dwell phase to support uniform contact and friction.

Force - Digitally tuned oscillation controls the amplitude, in turn controlling the G-force applied to the part.
VAD - Variable Acoustic Displacement, utilized in utilized for SLS and MJF gross depowdering (decaking). Software-tuned frequencies identify unique geometries while sound (pressure) waves function as a non-destructive mechanical energy source to de-cake powder. These functions are automatically monitored and adjusted in real-time in a closed-loop solution that repurposes powder.

Variable - Thermodynamic video and infrared monitoring control the decaking process, ensuring the process is scalable, and suitable for a variety of unique SLS and MJF parts.

Acoustic - Sound (pressure) waves do the heavy lifting, removing loose powder precisely and effectively while minimizing safety risks.

Displacement - The intelligent process releases, transfers, and recovers loose powder particles with minimal need for operator intervention. Removed powder can typically be reused, optimizing sustainability efforts.

Post-Processing & Additive Manufacturing (AM) Market Questions:

With the forecasted exponential growth of the additive manufacturing industry comes challenges for the market to scale to achieve its full potential (see our Annual Post-Printing Trends Report for more). One of these critical challenges is the bottleneck in post-processing, created as a result of methods that were adopted while the market was in its infancy.

Current post-processing methods are often highly manual with limited throughput, long lead times, and inconsistent quality. Examples include hand sanding and picking as well as manual finishing on conventional machinery, such as a waterjet system. This archaic model is unsustainable as print volumes grow, especially for industries with stringent conformance requirements such as automotive and aerospace. As such, the post-processing bottleneck can cause a company’s printing operations to halt and productivity to suffer while waiting for support removal and surface finishing to produce customer-ready parts.
Our automated surface finishing solutions are designed specifically for additive to produce a level of quality and consistency that is not possible using manual processes, sandblasters, or traditional vibratory tumblers – especially where there is fine feature detail, a key design feature of additive. Utilizing our software-driven surface finish solutions delivers three major benefits: consistency, significant increases in throughput, and enhanced productivity. This means faster processing times with less or no breakage driving better throughput.
While both water jets and traditional tanks often require additional manual labor to fully clean 3D printed parts, our automated support and resin removal options were developed as full-stack solutions, leveraging proprietary software, hardware, and chemistry to automate the process in full. PostProcess solutions also have much lower breakage rates compared to traditional options, as they are built to be conducive to the materials and intricate geometries of additive parts. Overall, our solutions are able to clean multiple parts simultaneously, increasing throughput and shortening cycle times.
We set out from the start to ensure our line of automated Production Series support removal and surface finishing solutions fit into a full production workflow. Our range of solutions work with all 3D print materials and technologies. Driven by intelligent software, our machines require minimal technician time to operate and include both pre-programmed and custom recipes to optimize finishing. Preventative maintenance schedules are also included to minimize downtime. PostProcess’ hardware is thoughtfully engineered within a compact footprint to save space on crowded production floors. We’ve formulated consumables specifically for 3D print materials for ease of use as “ready-to-use” solutions. These are just a few examples of how our systems were designed to integrate into the AM factory of the future.
Markets such as automotive and aerospace that lead the pack in projected AM growth are already disciplined in looking at efficiencies within every step of the supply chain. Automating the post-printing process allows the AM value proposition to be more fully realized and creates an even more compelling case for AM’s place on the manufacturing floor of the future. Redirecting human resources to spend their limited time on more value-added activities is a benefit of automation that everyone who is implementing additive manufacturing, not just automotive and aerospace, is seeking. Mass customization in several additional markets, such as dental and medical, are ramping up significantly and printing tens of millions of parts annually, requiring automation in every step of the additive process to remove production bottlenecks.
At a company level, we regularly implement and work on sustainability goals which we derive from the United Nations’ 17 Sustainable Development Goals. However, we also work hard to ensure every product we develop is even more sustainable than the last. Compared to traditional support removal methods, our software-driven technology improves workflow efficiencies while reducing energy, chemical usage, and the amount of time spent on manual labor. Additionally, many of our detergents utilize constituents that make them much safer than traditional post-printing chemicals.
