Technology & Products
Key Products
MSS-150 (Mini Sonic Screen) – batch processing small powder volumes up to 10L; MSS-1000 – powder handling for smaller volumes; CSM-300 – mid-size continuous coarse-fraction discharge; CSM-500 – compact screening down to 20 µm mesh; SPC-Compact – dry process atmosphere / industrial powder conditioning; SPC-Comfort – fully automated powder handling with external AM system integration; RoSM-300 – non-metal powder deagglomeration, gentle mixing & screening; RoSM-700 – larger rotary sonic machine; RoSL-300 / RoSL-700 – ultrasonic cross-flow filtration (solid-liquid separation); Automated conveyance & OEM integration (e.g. Trumpf TruPrint); ATEX-certified inert system components
Technological Advantage
CLAIMED: Sonic Speed Screen™ prevents powder contamination/agglomeration during repeated reuse cycles; delivers consistent powder quality across 100+ reuse cycles. VERIFIED: Patent protection for ultrasonic screening technology; integrated systems reduce post-print labor (manual de-powdering/sieving) by 70-80%; ATEX compliance enables safe operation in explosive atmospheres (critical for reactive powders like titanium). DEFENSIBLE: Trade secrets in ultrasonic excitation parameters + multilayer screening media (sourced from group company Dorstener Drahtwerke). REPLICATION RISK: Medium — core tech is ultrasonic screening, not proprietary to powder AM; competitors could develop similar systems.
Differentiation
Value Proposition
Recovers 80-90% of high-quality, reusable powder post-print through ultrasonic-assisted screening (Sonic Speed Screen™ technology), reducing powder consumption cost by 40-60% per print cycle while maintaining repeatability across 100+ reuse cycles; integrated safety (ATEX-compliant inert systems) and automated conveying eliminate manual handling risks and contamination.
How They Differentiate
Assonic's ultrasonic-assisted technology achieves finer sieving (20 µm minimum) with less powder degradation vs. standard vibratory screening; integrated ecosystem (screening + conveyance + storage + drying) reduces total system cost vs. point solutions; ATEX certification for reactive powder safety differentiates from generic screening suppliers; OEM co-engineering (Trumpf partnership) demonstrates system-level AM integration that competitors lack.
