6: Understanding your SCA

The Support Cleaning Apparatus (SCA) is a device specifically developed to provide
robust and efficient removal of support material from parts created with 3 D pri nters from
Stratasys, Inc. that utilize their Soluble Support Technology (SST). This is an improved
model based on the feedback received from SCA users in the Stratasys 3D Printer
community. The original SCA system was developed with input from Stratasys, users and
distributors of SST based systems.

6.1: How it Works

The system removes support material by immersing parts created with Stratasys’ SST
material in a warm bath of water with a specific amount of cleaning solution added (see
operating instructions). The SCA heats the water and circulates the heate d water around
the parts in the tank. The hot solution dissolves the support material without harming the
underlying model material. Over time, depending on geometry and the amount of support
material, all the support material is dissolved and the part is ready to be rinsed, dried and
used for its intended purpose.

6.2: Key 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.

8: Operating Your SCA

Figure 9: Fill Unit to MAX line

Although the SCA is simple to operate, it is critical that all users follow the instructions in
this manual and adhere to all safety guidelines.

8.1: Fill the Unit with Water

Make sure that the strainer is clean. Make sure
that the drain valve is in the closed position.

Fill the tank up almost to the MAX slot on the
rear support bracket. If you plan on running
large parts, it is advisable to fill to a lower level
(but above the Minimum level) to make room
for the parts and basket. DO NOT use hot water.
The addition of WaterWorks to water is a heat­releasing reaction and if added to HOT water
will result in dangerous spattering.

Never operate the tank unless the liquid leve l is ab ove the liquid leve l MIN slot on the heat
shield. This is just below the bottom edge of the rear support bracket.

8.2: Add Cleaning Concentrate to the Tank

Users have two approved options for cleaning concentrate: either WaterWorks or
Ecoworks, both available from your local Stratasys reseller. The WaterWorks soluble
concentrate contains Sod ium Hydroxide and care must be taken when working with the
solution and when disposing of it. Refer to section on Maintaining your SCA for disposal
instructions. The Ecoworks cleaning agent is both user- and eco- friendly. The
WaterWorks concentrate will generally remove support material in less time than the
Ecoworks. However, no personal protection equipment is required when handling the
Ecoworks concentrate and only dilution is required when disposing of the used solution.

If Using WaterWorks Soluble Concentrate:
Wearing protective gloves and proper eye protection, carefully and slowly add one

bottle (950 grams) of WaterWorks Soluble Concentrate P400SC into the filled tank. Never
add concentrate to a tank without water. Optimal pH for the cleaning solution using
WaterWorks is 12.6, and the solution begins to lose effectiveness below 11.5pH. Using
litmus paper on a room temperature sample of the solution is sufficiently accurate to
determine the pH.

If Using Ecoworks Cleaning Agent:

Carefully remove the entire contents of six packages (foil bags) and gently drop them into
the water in the tank. Make sure to use both sides A and B. Ne ver place the cleaning agent
in a tank without water.

Note: As the parts a re cleaned the cleanin g solution becomes saturated with the support
material and loses its effectiveness. Refer to the Troubleshooting section for further
information about determining when the solution requires replacement.

The unit is compatible with both North America 110V~50/60Hz and International

220V~50/60HZ power. The unit ships with both power cords. Onl y use a power cord
provided by the manufacturer.

It is strongly recommended that the unit be placed on a circuit with its own breaker with a
GFCI. The power circuit must be grounded.

Press the ON/OFF rocker switch. The display control panel should be on.
Press one of the four temperature preset buttons or the Heat Off button to select the cleaning

temperature. The temperatu re can be ch anged at any time duri ng the c ycle by select ing a
different temperat ur e button. If heating the water from room temperature to 70°C, it takes

again to accept the time. Press the button to start the heater and pump.

8.4: Loading Parts and Testing Le v el Sensor s

Wait until the SCA has reached the desired temperature before loading parts into the tank.
This minimizes the time the parts are immersed in the cleaning solution.

Open the lid on the large parts basket and place the parts inside.
For smaller parts, open the spring-latched door of the smaller, square basket, place the

part(s) inside and place small basket inside larger basket.
Before placing the basket into the cleaning solution, press the button to pause the

heater and pump. With the basket cutout facing the nozzle, slowly lower the large parts
basket into the solution-filled tank. The spray nozzle should be centered on the basket
cutout.

If the high level alert lights and the alarm sounds, press the button to silence the
alarm, and remove liquid by draining or scooping liquid from the tank until the alert
indicator is no longer lit.

Note: It is recommended that the level sensors be tested periodically. Adding water to
just above the MAX fill line should cause the high level alert to illuminate and the buzzer
to sound. Draining water until the liquid level is below the MIN fill line should cause the

SCAHTUM-03 18 SCA 1200HT User Manual

low level alert to illuminate and the buzzer to sound. If the level sensors are properly

Figure 10: Rest basket on tank

working the system will not operate until the liquid level is between the MIN and MAX
fill lines.

Never operate the tank unless the liquid level is above the liquid level MIN slot on the heat
shield. This is just below the bottom edge of the rear support bracket.

The system will not run until the liquid level is properly adjusted.

When adding or removing liquid from the tank, always remember that the tank liquid
contains cleaning solution. Always use gloves and wear eye protection when adding or
removing water from the tank. Never use aluminum or zinc containers.

Close the lids on the SCA to prevent heat loss and evaporation. Never place your face
near the tank when opening the lid – vapors from the cleaning solution may cause eye
and respiratory irritation.

8.5: Cleaning the Parts

To activate the cleanin g cycle after setting the time and temperature, and adjusting the
liquid level, press the button. Illuminated bars will sweep under the temperature display

when the pump is operating.
Parts can take a few hou rs or longer to clean. Cleaning time is affected by the size of the

part, the amount of support material, part geometry, and the pH level of the cleaning
solution.

Parts can be checked at any time during a cleaning cycle by opening the lid, carefully lifting
the Large Parts Basket from the tank, turning the basket 90° and resting it on the rear
support bracket and front tank ledge. Nev er place your face near the tank when opening
the lid - vapors from the cleaning solution may cause eye and respiratory irritation.

Protective gloves and eyewear should always be worn when lifting the basket from the
tank.

If the parts are clean before the end of the cleaning cycle, you can stop the cycle by pressing
the button on the display control panel.

After several cleaning cycles the cleaning solution becomes saturated with the support
material and loses its effectiveness. Refer to the Troubleshooting section for further
information about determining when the solution requires replacement.

8.6: Removing Parts from the Uni t

Once the cleaning cycle is completed or has been stopped, the
parts can be removed fro m the system. Open the lid, slowly
lift the Large Parts Basket from the t ank, turn the basket 90°
and rest it on the rear support bracket and front tank ledge.
Never place your face ne ar the tank when removing the lid ­vapors from the cleaning solution may cause eye and
respiratory irritation.

Let the basket rest abo ve t he t ank to let the liquid drain off of
the parts and the basket.

The proper gloves and eyewear should always be worn when
lifting the basket from the tank or handling wet parts before they
are washed.

ledge and bracket

Remove the parts and rin se them with wate r to wa sh awa y an y residual cleaning solution.
Air dry or pat dry with a cloth or paper towels.

Lower the basket into the tank and close the lid on t he tank when part removal is completed.

8.7: Readiness for the Next Cleaning Cycle

Once the cleaning cycle is completed and the parts have been removed, the system should
be turned off by pressing the ON/OFF rocker switch. Alternatively, if the SCA will be used
periodically use the 50°C temperature preset to maintain the water at an elevated
temperature. This will shorten the time required to heat the water to the optimal cleaning
temperature of 70 or 85°C.

If the system is not going to be utilized for an extended period, all liquid should be drained
from the system and the power cord should be removed from the wall socket.

SCAHTUM-03 20 SCA 1200HT User Manual

9: Maintaining Your SCA

As with any piece o f equip ment, prop er mainten ance is cri tical for safety and long life of
the SCA.

9.1: Cooling the Tank Liquid

Before draining the t ank, make sure that all parts h ave been removed from the unit. If
possible, open the lid to decrease the cooling time as well. Never place your face near the
tank when opening the lid - vapors from the cleaning solution may cause eye and
respiratory irritation.

Leave the power on to the system to indicate the liquid temperature. Once it has reached
30ºC the tank can be drained safely.

9.2: Draining the Tank

Never drain the tank unless the fluid is at or below 30ºC.
Prior to draining, turn off power to the tank and unplug from wall socket.
Always wear protective gloves and eyewear when draining the tank.
You should drain the liquid from the tank if the unit will not be used in th e near future or

if the liquid needs to be changed out because the cleaning solution is saturated with support
material.

Make sure that the strainer is in place at the bottom of the tank.
To drain the tank, attach a hose to the drain tube on the front of the unit. P lace the other

end of the hose in a sink, or a plastic or stainless steel container that will be used to transport
the liquid to a drain after dilution. Secure the end of the hose in the sink or container so
that it cannot come loose during draining.

Turn the drain valve to the “Open” position.
Once the tank is drained, make sure the drain valve is in the “Closed” Position.
Note: use 1” inner diameter PVC tubing or equivalent on the drain tube. Ensure the tubing

or hose can withstand the temperature and caustic properties of the cleaning solution.

SCAHTUM-03 21 SCA 1200HT User Manual

Figure 11: Drain Valve

9.3: Disposing of Solution

Used solution must be disposed of under applicable local waste disposal regulations. It is
the responsibility of the user to determine and verify what the local disposal
regulations are and to follow those regulations.

Proper disposal requires that the alkalinity (pH) of the solution be reduced to allowable
levels before it is disposed of. The pH may be lowered by either diluting the solution or by
neutralizing it by adding an acid. Litmus paper or an alternative method of measuring pH
levels should be used to d etermine if the p H level is within allow able levels bef ore disposal.

If you used the WaterWorks Soluble Concentrate, it is recommended that you dilute the
solution at a ratio of 5 parts clean water to 1 part used solution. More dilution may be
required, please check your local regulations.

If you are using Ecoworks cleaning agent, a dilution ratio of 1 part water to 1 part used
solution is sufficient for most applications. More dilution may be required, please check
your local regulations.

If you are ever unsure as to which solution was used in your SCA, assume that the
WaterWorks Soluble Concentrate was used and dilute accordingly.

9.4: Inspecting and Cleaning Drain S tr ainer

The strainer should be cleaned ev ery time the tank is refilled so it is clear of debris. You
should never remove the strainer when the tank is full of dirty liquid. Doing so will allow
debris to get into the drain tube.

The proper gloves and eyewear should always be worn when cleani ng and removing the
strainer. Never place your face near the tank when removin g the lid - vapors from the
cleaning solution may cause eye and respiratory irritation.

Figure 12: Strai n e r Removal

To remove the drain strainer, simply lift it up and out of the tank drain.
To clean debris from the strainer, scrub it with a nylon brush or a tooth brush and rinse

with warm water. Make sure that all holes are unplugged.

9.5: Inspecting and cleaning the pum p int a k e s cr e en

The pump intake screen may become clogged with debris. This will noticeably reduce the
flow in the tank.

Rinse with water. Verify all holes are unplugged before replacing the screen on the pump
intake.

9.6: Refilling the Tank

Refill the tank and add cleaning solution as described in sections 9.1 and 9.2.

9.7: Cleaning

The SCA should only be cleaned with mild soap and water with a sponge or cloth. Never
immerse the system or use a spray nozzle or hose to clean it. Any liquid in the electronics
area of the system may damage the system and void the warranty. Before using any
cleaning or decontamination method except those recommended by the manufacturer,
users should check with the manufacturer that the proposed method will not damage the
equipment.

9.8: Moving

Always use two people to lift the SCA. The SCA should always be drained before moving.
To lift, have each person stand on either side of the unit and place their hands into the
indentations under the unit. Lift the unit to a cart or wheeled table for transport.
