Instructions for Use

Software:

VisiJet

®

 PXL requires 3DPrint

TM

 latest software version and up to date firmware.

 
Color Setting:
On the ProJet 660Pro and 860Pro models, there are two unique color settings to choose from when

selecting your ProJet Core Type:

Vibrant - Produces bright, vibrant colors for display and showy VisiJet

®

 PXL models.

Pastel - Produces more natural skin tones, and accurate colors on your new VisiJet

®

 PXL models.

Infiltrating with ColorBond will bring out the best of these two new color settings for VisiJet

®

 PXL.

 
Processing:
Most parts can be removed from the build chamber as soon as the drying cycle is completed. For

best appearance, parts should be removed from the build chamber within 24 hours. If your 3D

model has thin, fragile features, allow it to dry for another hour in the printer, or in a 40-60°C

convection oven for approximately two hours.
Infiltration:
After your 3D model is dry and cleaned of excess core, it can be infiltrated. When high strength is

not critical, Salt Water Cure™ is a quick, easy way to finish monochrome parts. The best, most

colorful, concept models are made by infiltrating with ColorBond. StrengthMax resin will confer

superior strength for functional models.

*

For more information on the Water Cure procedure, please refer to the Appendix of this guide.

Sanding:
Parts can be sanded to improve the surface finish. Start with 100-grit paper and continue to 220-

grit if a smoother finish is desired.  If sanding an infiltrated part, please refer to the User Guide of

the infiltrant used for relevant safety information.
Painting:
Parts printed with VisiJet® PXL can be painted with most commonly available paints and coatings

without additional processing after being fully dried and depowdered. For the best surface finish,

sand lightly, use a primer, and then apply paint.

Appendix

Instructions for Salt Water Cure™

Salt Water Cure™ with Epsom salt is the best way to finish

concept models quickly and easily. No hazardous or restricted

chemicals are involved: simply dissolve the Epsom salt into

tap water and spray a fine mist over the surface of your parts

to give them a smooth, hard surface and a bright white

appearance.

The Salt Water Cure™ with Epsom salt method applies to all

monochrome parts printed using VisiJet® PXL

Salt Water Cure™ with Epsom salt can be used on color parts

but it may cause color muting and streaking.

 

Spraying vs. Dipping

IN MOST CASES, SPRAYING IS STRONGLY RECOMMENDED: it is quicker and easier than dipping.

Dipped parts require a large amount of salted water to be prepared and longer drying after

dipping. Dipping does not provide added strength as compared to spraying.
In cases where complete penetration of thick sections is desired, the dipping method should be

used.

Handling and Usage Information

The salt used in this procedure must be magnesium sulfate heptahydrate. In most countries, this is sold as Epsom Salt. Do NOT use any other type
of salt.
For storage & handling precautions of the dry salt, refer to the Epsom Salt package or consult your salt supplier.
While mixing the salt solution and finishing parts, we recommend wearing gloves and safety goggles.

Set Up the Work Area

Place a clean sheet of non-stick material (Teflon, freezer paper or wax paper) on your work area for easy clean up and to put your parts on as they

1.

dry.

Add a layer of paper towels where your model(s) will be placed to wick excess salt water away from your model

2.

Tip: Have a sheet of the non-stick material on a tray so parts can be safely moved while they dry.

 

For spraying, you will need a spray bottle (supplied with your starter kit or your upgrade kit).
For dipping, you will need a sturdy, clean, watertight container (example: plastic, glass) and a graduated container or some other means of
measuring volume of water and salt.

Spraying Method

Prepare the Salt Solution

Prepare the Salt Solution

Remove the spray head from the spray bottle.

1.


background image

Fill with Epsom salt up to the 7 oz line.

2.

Add tap water until you reach the 16 oz line.

3.

Tip: Using warm water helps the salt dissolve faster.

Note: if you're using a different spray bottle, use the mixing ratios provided in the dipping section of this document.

4.

Replace the spray head, close it tightly and shake for 1-2 minutes.

5.

If there are still undissolved crystals at the bottom, allow 30-60 minutes to dissolve and shake for 1 more minute.

6.


background image

Once all the crystals are dissolved, test the spraying and adjust it to a fine mist using the spray knob.

7.

 

Note: If the salt has not dissolved completely, you may experience poor spraying

performance. If the amount of salt mixed in is incorrect, the salt solution may be too dilute

and parts may become weak during spraying

Spray the part

1. Place your part on a flat surface coated with paper towels or wax paper.
Tip: Spread extra towels or paper around the area to catch any overspray.
This will make cleanup easier. Overspray can be wiped up with a damp
sponge or cloth.
2. Lightly coat one side of your part with a fine mist from a
distance of one to two feet (30-50 cm). DON’T TRY TO
SATURATE THE SURFACE - just a light misting is good. Make
sure the entire side is coated. Avoid touching the part where it has been
sprayed.

Carefully turn the part and coat the other side with a similar fine mist.

3.

Note: Fine structures/protrusions may be delicate. Over-saturating with water may cause

drooping/breakage of such fine structures.

 Let the part air dry for at least 5 minutes before moving it.

4.

Tip: A fan or hair dryer can be used to harden the surface layers more rapidly. This allows for quicker handling. Note the part may still be weak, so

handle with care.


background image

Dry the Part

Allowed to air dry at room temperature, the part will be dried to touch within a couple hours and

fully dried within 24 - 48 hours.
For faster drying, the parts can be placed in an oven set to 70˚C for 1-2 hours. This also helps

guarantee maximum whiteness of the parts. Drying time may vary depending on your oven and

the size of your models.

Note: If you dry your models at room

temperature, a pattern may appear on your

parts after several days. See photo to the

right (contrast has been exaggerated to

make it more visible).

This may be prevented or removed from a

part by drying it for 1-2 hours at 70°C.

 

Dipping Method

Prepare the Salt Solution

Measure enough tap water into the container to submerge your part completely and allow room for handling.

1.

Allow room in the container for the volume of salt and for the water that will be displaced by your part.

2.

For each 1 volume of water, add 0.7 volume of salt (see table below).

Tip: Using warm water helps the salt dissolve faster.

Stir the water solution intermittently until the salt completely dissolves (5-10 minutes). If there are any undissolved crystals at the bottom, allow 1-2

4.

hours to dissolve, and then stir again for 1-2 minutes.

Note: Failure to dissolve all the salt could cause crystals to deposit onto your part when you

dip it.

Dip the part

Tip: Wear gloves while dipping models to keep the bath clean and prevent mold growth.

Gently submerse the part in the bath for at least 5-10 seconds or until bubbles subside.

1.

Slowly remove the part and hold it above the bath for 5-10 seconds to allow a majority of the excess water to run off. Rotate the part to help the

2.

water escape from any cavities or crevices.

Move the part to the paper towels and gently dab the bottom of it on the dry paper towels.

3.

Tip: Avoid wiping the excess water on the top surfaces with a paper towel as this will
compromise surface finish.

Place the dipped part on the wax paper and allow it to air dry for 1-2 hours before handling.

4.

Tip: A fan or hair dryer can be used to harden the surface layers more rapidly. This allows for
quicker handling. Note the parts may still be weak, so handle with care.

Dry the Part

Allowed to air dry at room temperature, the part will be fully dried within 24 - 48 hours.
For faster drying, the parts can be placed in an oven set to 70˚C for 3-4 hours. This also helps guarantee maximum whiteness of the parts.

Clean Up

Any overspray is easily cleaned up with a wet cloth or sponge.
The salt solution may be covered and reused for up to one week. Always check the solution before any subsequent uses - if the solution is cloudy
or discolored in any way, discard it and make a fresh batch.
The salt solution may be safely disposed of by pouring down a sink drain and flushing with plenty of water.
