We have four proprietary, software-driven technology approaches:
TAF - Thermal Atomized Fusillade, utilized in our Hybrid DECI Duo. Two perpendicular single-axis jet streams comprised of compressed air,  detergent and suspended solids providing targeted blast sequences while utilizing 360° part rotation for maximum surface exposure.

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 Support Removal family of solutions. A rotating motion while immersed in the fluid for disposing support material and providing 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 vapour 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.
Our automated support removal and surface finishing solutions are compatible with a number of 3D printing technologies, both plastics and metals. The following printing technologies have been tested by PostProcess and include PolyJet, Fused Deposition Modelling (FDM), Stereolithography (SLA), Selective Laser Sintering (SLS), Digital Light Processing (DLP), MultiJet Fusion (MJF), Direct Metal Laser Sintering (DMLS), Directed Energy Deposition (DED), Electron Beam Melting (EBM) and more.

This is dependent on the part size and the machine size. We offer both Design Series options for R&D or pilot operations and Production Series options for higher throughput needs.
Roughness Average (Ra) is the arithmetic average value of the filtered roughness profile determined from deviations about the center line within the evaluation length.

Rz: the average maximum peak to valley of five consecutive sampling lengths within the measuring length, since Rz averages the highest peaks and lowest valleys, extremes have a much larger impact than in Ra.
Mechanical Rate of Removal and Chemical Rate of Removal. Data collected to measure support removal and surface finishing efficacy for individual energies of our comprehensive solutions; measured in grams/min and Ra, respectively.
PostProcess systems help solve the breakage challenge that plagues manual solutions and traditional vibratory tumblers. All PostProcess production systems are capable of precision energy management – the amount of motion, heat and detergent is optimized to the part. This protects the part while creating unmatched results.
PostProcess’s DECI Duo is world’s first automated, intelligent, hybrid post-printing solution, designed for both surface finishing and support removal in one compact footprint. Engineered specifically for 3D printing, the combination of proprietary software, patent-pending hardware, and specially formulated consumables as a complete system is the only one on the market capable of performing two post-processing functions in one machine. Its multi-functionality extends to its capability of finishing a number of 3D print technologies, including FDM, SLS, SLA, Multi Jet Fusion (MJF) and numerous metal printing technologies.

One of the DECI Duo’s most innovative features is the utilization of our specially designed detergents and suspended solids to address complex materials like advanced thermoplastics and metals. Working in conjunction with our proprietary software and patent-pending hardware, we produce a precise mixture of detergent and suspended solids that are precisely discharged over the surface of the part with an exacting combination of flow, heat, and air pressure.

The DECI Duo delivers fast cycle times and replicable, high-quality uniformity, even with complex geometries. It allows for formerly impossible-to-reach internal geometries to be cleaned, such as conformal cooling channels in 3D metal printed parts.
Our founder, Daniel Hutchinson, thoughtfully named our Support Removal series of solutions with an engineering audience in mind using the metric prefix, or SI prefix, system. The naming correlates the size of the machines to their relative place in the decimal system. Our Surface Finish series of solutions plays off the Latin language influence of the metric prefix system and is comprised of modified Latin words for clean, smooth, polish, and shine.

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. 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. These 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 designed specifically for additive produce a level of quality and consistency that is not possible using manual processes 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.
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 systems 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 and with “library quiet” features for a low dBa. 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. Automation 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, are ramping significantly and printing tens of millions of parts annually requiring automation in every step of the additive process to remove production bottlenecks.
