Overview
The SCA 1200ht Support Cleaning Apparatus (SCA) is designed to remove soluble
support from FDM parts (PLA, ABS, PC, nylon) and Material Jetting (MJ) parts (UV Cured
Resins) using water or approved caustic cleaning solutions.
How it works
The SCA removes support material by immersing parts created with soluble support
material in a bath consisting of water or cleaning solution. The SCA is designed to
accommodate a broad range of material specific cleaning solutions and bath
temperatures. The gentle bath agitation dissolves the support material without harming
the underlying model material. The time required to remove the support material
depends on model geometry and the total amount of support material. When the
soluble support material is completely removed, models are unloaded from the SCA,
rinsed, dried, and ready for further finishing or use.

Major components
The SCA consists of several key components that all users should be familiar with.
Understanding the function of each component is important for the safe operation of
the system and will aid in extending the life of your SCA.
Many aspects of the SCA have been designed specifically for safety. All electrical
components are properly grounded and labeled for safety protection.

The Tank Area is used to hold the liquid and it is where the parts are cleaned. The SCA
improves part cleaning by circulating the liquid in the tank.
The Large Parts Basket is used to hold parts during cleaning and to lift parts out of the
tank. Users should wear thermal gloves when lifting the basket from the tank.
The Small Parts Basket is used to hold small parts during cleaning.

The Strainer over the drain opening in the tank prevents debris from entering the drain
when the tank is emptied. It should be rinsed after emptying the tank before refilling
with fresh liquid.
The Heater is located behind the perforated Heater Shield. It heats the water in the
tank.
The Spray Nozzle directs the flow of liquid into the tank. The spray nozzle can be
removed for cleaning if the holes are clogged. Simply unscrew the nozzle and rinse with
tap water to un-clog holes.
The Pump Intake Screen prevents large particulates from entering the pump. It may
occasionally need to be cleaned with a soft brush or toothbrush to remove debris
trapped in the holes.
The Temperature and Level sensors are used to sense the temperature and height of
the liquid in the tank. They are mounted behind the rear support bracket.
The Main Power Switch is located on the right-hand side of the unit. This turns power to
the unit on and off.

The Power Cord (not shown in figure) is used to connect the system to a wall outlet for
power. Only use a power cord provided by the manufacturer.
The Power Cord Receptacle is where the power cord is connected to the unit. The plug
is a disconnecting device and should be easily accessible at all times.
The Drain Tube and Drain Valve are on the front of the tank for easy accessibility.
The tank is drained by connecting a hose to the Drain Tube and turning the Drain Valve
to the open position. The liquid in the tank should be at room temperature and the unit
should be turned off and unplugged from the wall before it is drained.

Setup
Locating the SCA
To maximize ease of use and operational safety, make sure the following preparations
of the physical site are met:
•Place the SCA on a sturdy horizontal surface or cart capable of supporting 200 lbs
(the weight when filled with water).
•The selected location should be isolated from unintentional contact from those
working in the area.
•The electrical outlet must be located within 2 m (6 ft) of the SCA. Do not use an
extension cord or power strip with the system.
•The SCA should be near a grounded wall outlet such that the power cord does not
pose a hazard to people or equipment passing by.
•The grounded electrical outlet (US: 110VAC, 20A, 60Hz, single phase, Europe:
220VAC, 16A, 50Hz)
•The power cord plug-in receptacle is a disconnecting device that should be easily
accessible at all times. Position the unit so that the plug can be easily reached.
•It is strongly recommended that the unit be placed on a circuit with its own GFCI
breaker.
•Place the unit in a well-ventilated area.
•The operating environmental temperature must be between 5⁰C - 40⁰C (41⁰F –
104⁰F); and operating environmental humidity between 0% - 80% RH.
Preparations for draining and disposal
•Consult your local regulations regarding disposal of the cleaning solution effluent
prior to use. A permit or form of pre-treatment may be required.
•The SCA relies on gravity to drain the cleaning tank. Locating the system near a drain
or sink will make draining the unit much easier. Alternatively, the SCA can be kept on
a cart for easy transport to a sink or drain.
•Use a 1” inner diameter hose made of PVC or equivalent on the drain tube to
facilitate draining. Ensure the tubing or hose can withstand the temperature and
caustic properties of the cleaning solution.
