About FunToDo

 

  • What is FunToDo material?

FunToDo 3D resin is one of the best 3D resins on the professional 3D printing market. This material differs from competitors in high printing accuracy and polymerization speed, the material is durable and safe for health.

  • Is it suitable for my printer?

The resin is compatible with almost all DLP and SLA 3D printers on the market. The combination of an affordable price, as well as a short exposure time, allows you to significantly save your funds, reduce the cost of 3D printing and the lead time.

  • What is the period and storage conditions so that the material does not deteriorate?

There are no restrictions on storage in a box (in a place protected from light). The resin can be stored for quite a long time – we tested the material from three years ago, the print quality and other properties have not changed.

  • What should be done before printing, after a long period of storage?

The main thing is to shake the container with the polymer well before use, for 5-8 minutes. It is especially important to mix well opaque resins with a high concentration of coloring pigment.

 

Washing and post-processing of FunToDo 3D resin products

 

Note! The final surface quality and mechanical characteristics of the model are 80% dependent on how well you do the processing of the model after printing.

  • How to wash the model after printing?

After printing, the model must be washed immediately. Ethyl alcohol (ethanol) or isopropyl alcohol (isopropanol) diluted to 40-60% approach perfectly. It is possible to use a universal cleaning solution, such as TEK1960. Alcohol must be diluted!

First, rinse the model in previously used alcohol to wash off most of the excess resin. Next, use a toothbrush to clean the remaining material from the small parts.

To achieve maximum results, place the model in the ultrasonic cleaner for 2-3 minutes at a power of 50 watts.

If the model is left in ultrasonic cleaner for more than 5 minutes, the polymer may be partially washed out between the layers, since there it has not completely hardened yet – a barely noticeable mesh may appear on the surface of the model.

Alcohol residues can be washed off with demineralized water.

  • How to dry the model after printing?

After washing, the model must be dried well. Ideally, with compressed air, a powerful hair dryer without heating is suitable at home. Pay special attention to removing excess photopolymer from hard-to-reach places, such as small diameter holes.

  • How to remove the supports?
Removing supports FunToDo resins

Carefully remove supports. A scalpel, clerical knife or scissors is perfect. If necessary, additionally rinse again in ultrasonic cleaner (1 min), then dry again with compressed air. Now the model is ready for final fixing.

Before final fixing

 

This step is optional. Place the model in a dry, dark place at room temperature for several hours so that the material “rests”. If an incubator is available, 30 minutes is sufficient at 38°C.

In order the model to be solid and durable, and the geometry does not change over time, the model must be kept in the sun or in a UV chamber. To do this, put the model in the sun for 2-4 hours, turning every 30-60 minutes. If you are using a UV chamber, 20-30 minutes will be sufficient. Depending on the size of the model and the capacity of the curing chamber, more time may be required.

  • Burn out resin the same way as wax?

Casting from 3D resin and wax are two different processes. The photopolymer is not melted but burned out. Accordingly, the process and cycle of burning is completely different.

  • How to prepare a model for burning?

After construction, the model must be immediately washed in an alcohol solution of 40-60% ethanol in ultrasonic cleaning for no more than 5 minutes.

Dry and remove liquid resin from hard-to-reach areas before drying and photo-curing.

Remove supports and, if necessary, rinse again in ultrasonic cleaning (1 min), then dry again.

Place the models in an incubator (38°C) for 30 minutes or in a dry, dark place at room temperature for 6 hours.

Place the models in a UV chamber or in the sun until fully cured (about 2-4 hours depending on size, turn every 20-30 minutes).

  • What forming mass to choose for burning resin?

For casting precise models, for example, jewelry, Plasticast molds are used. For regular Satincast products, as a more affordable option. Molds Goldstar KB may not be suitable, because when casting 750 gold, the products are rough.

  • The molding mass cracked in the flask, what should I do?

Try to burn the resin slowly using an 8-hour schedule.

If you use an accelerated burnout mode (2 hours), then you should use an expensive molding sand that has an expansion when heated by more than 1% so that it does not crack in the flask.

The burnout process

1. Mix the mold according to the instructions. Standard: 38 ml of water (24-26 degrees) per 100 g of powder.

2. Leave for 2-4 hours before placing the flask in the oven (depending on the size of the model).

3. Place the flask in an oven preheated to 160°C for 2 hours.

4. Heat the oven to 370°C (120°C per hour) and hold at this temperature for 1 hour. This step burns out the polymer. If the part is large, you need to increase the time.

5. Heat to 730°C (120°C per hour) and hold at this temperature for 2 hours.

6. Cool to pouring temperature, hold for 1 hour.

7. Before casting the model, ventilate the flask.

Conclusion

The FunToDo burnout resin gives amazing detail when printed on a 3D printer. Following this instruction, the resin is burned out completely and no ash remains.

The calcination schedule is better to choose a full-fledged, long one (on the Slow Burnout chart). In the accelerated burnout mode (on the Flash Burnout graph), you should use expensive molding sand that has an expansion when heated by more than 1% so that it does not crack in the flask.
