Technology & Products
Key Products
MSS-150 (Mini Sonic Screen) – laboratory & small batch powder processing (up to 10L); MSS-1000 (Mini Sonic Screen) – intermediate batch processing with integrated conveyance; CSM-300 (Compact Screening Machine) – medium-volume metal powder conditioning for 1-3 printers; SPC-500 (Powder Conditioning System) – large-scale metal powder prep for multi-printer industrial operations; RoSM-300 (Rotary Sonic Machine) – plastic powder agglomerate dissolution & conditioning; SPC-Compact – modular compact industrial solution for high-efficiency large-volume powder; PTC-150 (Powder Transit Container) – temporary storage & conditioning between print cycles; Automated conveyance & integration modules – seamless integration with printer ecosystems (Trumpf TruPrint, others); ATEX-certified inert system components – explosion-safe powder handling
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.
