INTRODUCTION
The Wash-1 is a solvent debinding station, used to remove wax binder from parts printed on the Markforged
Metal X 3D printer.
Printed “green” parts are placed in a basket which is lowered into an immersion chamber. Solvent is heated in
the boil chamber and cooled by condensing coils for recapture in a water separator. The solvent is returned
to the immersion chamber.
After a prescribed length of time, the chemically debound part is removed, air-dried, and weighed to determine
is ready to sinter in the Sinter-1 furnace. If not, additional wash/dry cycles are necessary.
The Wash-1 is the simplest of the three Metal X System components to install, operate, and maintain. The user
must periodically replenish the boil chamber with fresh solvent, drain the water separator, and occasionally fully
This User Guide includes instructions for all common user procedures; rare service procedures are covered in

SAFETY NOTES
Note: Consult the Safety Sheet included with your device for an explanation of the safety icons used in
this manual. .
HEATED SOLVENT WASH
The Wash-1 debinding station uses solvent heated to a maximum of 130OF. Consult the Opteon SF79 SDS and
follow all handling and safety precautions within.
POWER DISCONNECT ACCESS
accessible at all times.
REDUCING RISK OF INJURY
Never touch heated solvent. To avoid contact with solvent vapor, never reach below the condensing coils inside
the Wash-1.
REDUCING RISK OF FIRE
Do not power on the Wash-1 without solvent loaded into the tank.
USE SAFE LIFTING TECHNIQUE
Follow safe lifting procedures. Never attempt to lift the Wash-1 unit alone. See Pre-Install Guide for details.
HAZARDOUS VAPORS
Immediately clean up and dispose of any spilled solvent, observing any local regulations for disposal of
chemical waste. Avoid breathing in vapors. Wear protective equipment when cleaning up spills. Never operate
Wash-1 or handle solvent without adequate ventilation. Do not leave immersion chamber door open when
REFRIGERANT LEAK
In case of refrigerant leak, immediately contact your Reseller.
ALWAYS FOLLOW SAFETY INSTRUCTIONS
Follow all safety instructions posted on the unit and in the written documentation.

LOADING SOLVENT
WARNING: The solvent in the Wash-1 has a defatting effect on skin. Use chemical-resistant gloves,
included in the accessory kit, when in contact with this solvent. Do not place hands below coils.
Supplies
●
●Siphon from Wash-1 accessory kit
●Chemical-resistant gloves
1. Heater switch on the dashboard to the
position, but do not unplug the unit.
2. Carefully open the Opteon SF79 near the Wash-1 station and place container on top of the Wash-1, on
the right-hand side.

WASH OVERVIEW
The Wash Overview feature in Eiger allows you to track your parts through the Wash-1 debinding process. The
Wash Overview also allows you to record the initial and end masses of parts to help you determine when a part
WASH TIMES AND BATCHES
The Eiger software only recommends minimum Wash-1 chemical debinding times. The Opteon SF79 solvent
will not damage the part, and It is important to fully debind each
part in the Wash-1 to avoid potentially damaging wax buildup in the Sinter-1 unit.
However, a part that remains in the immersion chamber for an extended period may be jostled and damaged by
contact with other parts or by the Wash-1 operator. We recommend carefully tracking wash times and batching
wash cycles to avoid physical damage.

Note:To calculate % mass loss, subtract the mass of the washed (brown) part from the mass of the
unwashed (green) part, then divide by the mass of the green part.

It is important to maintain the vertical orientation of your part throughout the printing and sintering processes,
and drip-dry. For instance, bowl-shaped parts should be washed upside-down if possible, to drain any recessed
areas where solvent might accumulate. This will aid in solvent recovery; it will also let you avoid pouring large
quantities of solvent back into the immersion chamber, which could cause splashing. Additionally, the solvent
will permeate upward into the part more quickly, reducing wash time.

UNLOADING PARTS
WARNING
●Use chemical-resistant, forearm-covering gloves when handling solvent-covered parts
●Always take extra care when working near the coils of the Wash-1
●Never reach past the coils in the immersion chamber where solvent vapor condensate accumulates
●Close the immersion chamber lid after loading and unloading parts in the Wash-1
●Solvent can potentially splash onto clothing, skin, or eyes when loading or unloading parts.
1. Check the Wash Overview to ensure that the parts have been in the debinding solvent long enough.
Note: Completing the debinding process is a critical step. You must never sinter a part that has
not yet been washed.
2. Open the immersion chamber lid.
