How to print with Wargamer

1. Parameters

Find the right exposure times for your 3D printer using a validation test.

We recommend starting from 2.5s normal exposure time and 30s bottom exposure.

All other settings can be left at default value.

2. PPE

Always wear appropriate PPE (personal protective equipment) when handling resin.

This includes nitrile gloves, safety goggles and a respirator. Minimise your skin exposure by wearing long sleeves and trousers.

3. Temperature

Wargamer is intended to be used at temperatures between 20-35°C.

If your ambient temperature is significantly lower than this, consider using a heating method.

4. Mixing

Always mix your resin before use. Shake the bottle or stir it inside the vat.

Some ingredients inside the resin naturally settle to the bottom, like bits in orange juice. Mixing the resin makes the material uniform again, which is optimal for printing.

Shaking will usually create some bubbles inside the resin. Wait about 10 minutes until these have dissipated before starting your print.

5. Printing

Pour in carefully, and start your print.

Do not leave the resin bottle open for too long. Extended exposure to air and light deteriorates the material.

If you need to add more resin to the vat, make sure this is the same temperature as what is already inside.

Once printing is finished, retrieve the part as soon as possible. If left for a long time, it could start soaking humidity from the air around it.

6. Washing

Washing in water

Use a spray/squirt bottle to wash the print with clean water.

Catch any dripping ‘dirty water’ in a container. Once this container fills up a bit, you can use it to pre-rinse other pieces before spraying them.

We don't recommend using a wash station. All the water inside will immediately become contaminated with resin, and contaminated 'dirty water' does not clean as well as fresh water.

Your total wash time should not exceed 3 minutes. Otherwise the print will start to soak itself with water, which makes it soft and weak.

Water mixed with resin is toxic. Do not touch it with bare hands, and do not wash it down a drain. The contaminated water needs to evaporate, leaving just resin behind. This is best done by leaving the resin outside in a wide container/tray. The fresh air will help the water evaporate, and the sun's UV rays will cure any leftover resin. The cured resin can be safely thrown away. If leaving it outside is not an option, putting a fan in front of the container is a cheap way to speed up evaporation. Any leftover resin can also be cured with a UV light.

Washing in IPA

Wargamer can also be washed with IPA or other solvents. We recommend this approach to professionals and heavy users.

Washing in IPA is the same as for any other resin, except the total wash time should not exceed 3 minutes, and the print needs to be thoroughly dry before curing.

7. Drying

Dry your print very thoroughly of any leftover water.

Drying can be done using a hairdryer, food dehydrator, filament dryer etc.

The temperature of the drying air should not be over 60 degrees, as this may lead to the softening of the print.

Do not skip this step.

Wet prints will come out tacky, soft and jelly-like.

8. UV curing

Post-cure for 5-10 minutes using a UV curing chamber or UV curing light.

The exact optimal curing time will vary by the exact device you use and your ambient temperature, but 5-10 minutes is a good rule of thumb.

It should now be safe to touch the part with your bare hands.

9. Coating

Spray the print with a primer or sealer.

The coating will protect the print from absorbing moisture from the air, which could lead to softening or cracking in water washable resins.

Non-water-based primer is preferable.‎

Primer is also necessary if the finished part will be painted.

10. Waiting

Wait 24 hours before applying considerable force to your print.

Resin undergoes serious chemical changes during the printing process, and needs some time to rest. The hardened material looks static, but it still has a lot of internal stresses that it needs to dissipate.

While your print will be safe to handle now, it still needs a few hours to achieve all the strength and durability Wargamer is capable of.

11. Storage

Water washable resins should not be exposed to air, humidity and light for long periods of time.

If leftover resin in the vat will not be used again for over 24 hours, it should be poured into an air- and light-proof container.

This can be the original resin bottle, however if the used resin is somehow contaminated, this will contaminate any fresh resin as well. Use a filter when pouring.

Resin bottles should always be kept in a cool, dry place away from sunlight.
