LÖMI GmbH, Grossostheim,
Germany, has launched a new system solvent debinding series EDA-AM to meet the
increasing demand from the Additive Manufacturing industry. The company
states that the three systems offer three-in-one functionality by integrating
debinding, the drying of parts and solvent recovery. This is said to save time
and cost, as no additional handling of the parts is required between the
debinding and drying process steps, while the integrated solvent recovery
ensures a continuous supply of fresh debinding medium.

LÖMI’s smallest AM solvent
debinding system, EDA-30, is a tabletop unit with 16 litres batch loading
volume for research, prototyping and small batch production. It is water-cooled
and offers basic automation. The two larger systems EDA-30AM and EDA-50 both
feature integrated tanks for the clean and used debinding solvent. The EDA-30AM
is a semi-automatic air-cooled system with 16 litres batch loading volume,
while the water-cooled EDA-50 offers 26 litres batch loading volume and full
automation. It is PLC-operated, and a touch display shows real-time process
parameters to facilitate process control.

“The solvent debinding
process offers a number of advantages including a greater freedom of feedstock
choice for AM part producers, as a wide range of feedstock can be
processed,” explained Christian Ferreira Marques, Managing Partner at
LÖMI. “This enables part producers to test new feedstock and to optimise
their processes, without having to invest in a another debinding system and
without becoming dependent on a single feedstock producer.”

Ferreira continued, “In
addition, various organic solvents can be employed, such as ethanol,
isopropanol and acetone. Solvent debinding systems offer very compact
dimensions and are very economical in their operation due to their low energy
consumption and very long lifetime, as the solvent debinding process causes
very little wear and tear. The solvent is continuously reprocessed with a rate
of up to 99% and returned to the process in a closed system. This makes our
systems very safe and environmentally beneficial.”
