Fun to Do Resin Review (2021)

Fun To Do is a Dutch company based in the small town of Alkmaar. Photopolymers of this company are distinguished by a high polymerization rate. Compatible with almost all DLP and SLA 3D printers. The resins have a very low shrinkage percentage (about 0.5%) and a wide range of exposure wavelengths from 225 to 415 nm. In resins Fun To Do is not a pungent odor in comparison with many other polymers, as they do not lead to strong irritation in contact with skin.

At the moment, the range includes 5 types of resin: standard, industrial, casting, Snow White (white polymer, with the possibility of adding a pigment), Deep Black (with carbon particles for high accuracy of models).

Resin types

Fun To Do Standard Blend

Standard and inexpensive resin. It is the best solution for beginners. Good for making prototypes or master models. Resin has a high cure rate and high detail, for 3D printing with a layer of 20 to 50 microns.

Fully cured polymer, Fun To Do Standard Blend has a hardness of 35D Shore.
Available in 3 colors – red, black and natural.

Fun to do snow white

Fun To Do Snow White is a resin that remains snow white after printing. You can also add one of 4 dyes to the resin (red, blue, yellow or black) to obtain any color and shade. 5 ml of polymer is sufficient for coloring 1 liter of polymer.Fun to Do Resin Review (2021) 2

The hardness of the fully cured polymer is 83 Shore.

Fun to do industrial blend

High strength industrial polymer is ideal for functional prototypes. At the same time, Fun To Do Industrial Blend retains its properties at very low and very high temperatures. It has been tested over a temperature range of -45 ° C to +225 ° C. This makes it one of the few polymers that are ideal for the vulcanization process.

The fully cured polymer has a hardness of 75 Shore D.
The resin is available in 3 colors – red, black and natural.

Fun to do deep black

The resin is designed for 3D printing of objects of the highest precision. Resin is a combination of a special mixture with carbon particles, which allows you to print models of the highest resolution. The 3D printed model looks like molded plastic.

The hardness of the fully cured polymer is 81 Shore D.
The resin is available in black only.

Fun to do castable blend

Castable resin. Designed for melting and subsequent casting with metals.

The hardness of the fully cured polymer is 73 Shore D.

  1. For burning out, you need to place the flask in an oven heated to 150C for 2 hours.
  2. Then heat up to 370C and keep at this temperature for an hour.
  3. Heat to 730C and hold at this temperature for 2 hours.
  4. Reduce temperature to pouring temperature and wait 1 hour more, then pour.

Since the polymer is not melted, but burns out, the muffle furnace must be with forced ventilation.
The resin is only available in red.

Answers to popular questions

Clients often call us with questions about resin properties. Here we have compiled a selection of the most popular questions.

How many times can you use a polymer “run-off”?

There are no clear criteria. When printing, part of the pigment passes into the model, part settles. Just remember to stir the resin before every print.

What is the shelf life and conditions of polymer storage?

There are no restrictions on storage in the bank. The main thing is to shake the polymer well before use. When storing resin in the printer tray, do not expose the resin to light. Stir the resin well before use (pigment may precipitate).

How can models be glued?

You can glue with ordinary superglue or any other glue for plastics.

Printer exposure time settings.

Standard exposure time of layers: 3-5 sec. But the exposure time may vary depending on the power of the projector lamp or laser. For example, for Wanhao 7 it is 12-15 seconds, for Flash Forge Hunter – 1.8-2 seconds per layer.

The exposure time of the first 3-5 layers (fasteners) is usually up to 5 times longer than the subsequent layers.
When printing models with thin walls, the exposure time should be increased to avoid the possibility of gaps.

Our impressions

We tested FTD resin on FlashForge Hunter and Wanhao Duplicator 7 resin 3D printers… The resin was found to be very unpretentious and easy to use. It gave stable and good results on both printers. Due to its good fluidity and low viscosity, even very small parts are printed without streaks and roughness. Of the advantages, one can also single out a high curing speed, real numbers were written at the very beginning, and a slight shrinkage. Although of course this also depends on the power of the projector of the printer you are printing on. And one more obvious plus, in our opinion) The prices for Fun To Do resins are very affordable and the price-quality ratio is directly proportional to each other. Below are photos of our models printed with FTD resins. In fact, there are many more of them, we will gradually share with you. =)
