Finishing

SLA/DLPIPA or TPM agitation bath (30-45 mins)

Manual/Hand tools (pliers, razor blades)

Bead Blast or Hand Sand

Water hone for standard ‘frosted’ finish

Up to 20hrs/part hand sand + clear coat for ‘water clear’ finish

FDM

Sodium Hydroxide- Parts submerged in SCA or Waterworks system.

Parts need to dry for 6-24+hrs. Fans are utilized often.

Hand sand, acetone or vapor smother chamber.

Prime and paint where required.

POLYJETBulk removal, or let parts soak in water overnight.

Waterjet system or hand tools. Hand sand

Conventional Submersion Tanks


DECI/BASE TECHNOLOGY

Volumetric Velocity Dispersion (VVD)

A series of high volume and flow jet streams spraying bidirectionally coupled with perpendicular linear motion for mechanically assisted support removal.

Volumetric- Proprietary PPT detergent is circulated at a rate of up to 150 gallons per

minute (GPM) while maintaining low pressure, around 35 PSI.- For reference: Garden hose flow is ~24 GPM, Fire Hose is ~500 GPM

Velocity- High speed flow optimizes the Rate of Removal (RoR), leveraging steady

mechanical force to dispose of support material as it weakens.

Dispersion- Jetted agitation engulfs the part with an optimized droplet size through

two rack manifolds with linear control for sweeping and targeted coverage.

Low Pressure; High Volume, High Velocity- 15 - 35 PSI (garden hose)- 150 GPM

Agitation Algorithm optimizes flow- Varying energy levels, targeted rack limits

Auto drain, fill and dose chemistry - No manual mixing- Detergent is recycled internally

Quick part drying (no submersion)Best for:

- FDM- Average cycle time reduction > 50%

- SLA:- Resin removal; printer build tray frame

Maintenance:- Automated maintenance settings & reminders- No filtration to maintain- Sanitary clamps for virtually tool-free maintenance- High Mean Time Between Failures (MTBF)- Low Mean Time To Repair (MTTR)

DECI/BASE Notes


Alternate Systems


DECI / BASE Conventional Flow/Ultrasonics Tanks

Monitors and auto-doses detergent to maintain proper pH level; PM warnings

Requires manual draining and refilling tank if efficacy drops

Part feels near-static, low pressure force with bi-directional flow from top and bottom, minimizing damage risks.

Ultrasonics On/Off only; risk of warpage or delayed cycle if running unattended. What if cycle starts at higher temp?

Full immersion without soaking parts, leading to faster dry times for additional post-processing (i.e. surface finish, dye, etc.)

Uneven support removal leading to cracking & longer dry times; Floating parts exposed, sinking parts not rotating

Ability to optimize cycle time via AUTOMAT3D settings

Limited variables to control; manual, no variable agitation

One-button recipe selection for repeatability and eliminate user error

User selects process parameters individually

Updates via software (customer feedback, etc.); remote support

Stagnant ‘software’; updates require purchasing a new model

DECI Performance Eval


- How often does the detergent need to be emptied in the SR machines?- Water based detergents require only that the system is topped off

when as it evaporates - the DECI/BASE do this automatically. Depending on usage, a complete change out may be required 2-3 times per year (higher for SLA today)

- Cleaning larger debris from debris filter will extend detergent life.

- How potent is the smell of the detergents?- Tested safe. Respirator not required. Similar to D-Limonlene (citrus)

- Can multiple technologies and materials be run simultaneously?- No - PG1 (PolyJet), PG2 (FDM) PG1.1 (SLA)- DECI/BASE can power drain and fill

- How much detergent/media is required to operate each machine?- SR Spray (DECI/BASE) require approx 20 & 40 gallons, respectively.

FAQs


- Do the detergents have to be diluted?- NO - PG concentrate is auto-dosed with municipal supply

- What is the change over times for switching the different detergents?- Typical change over times for the different detergents on our DECI/BASE is 15 minutes. Power drain drain and fill.

- Can I go ‘straight to drain’ when draining tank?- Depends on local regulations. Reviewed during the sales process

- Average process times for the VVD systems: - DECI/BASE are spray systems with average processing times of sub 1hr
