Another great option is the Siraya Tech Tenacious 3D Printer Resin. This printing resin is created by Siraya Tech with flexibility and high-impact resistance in mind. It is made as a popular photopolymer resin for 3D prints and miniatures.

Along with this, it can double as an additive for increasing the elasticity and strength of other resins. The product comes with characteristics and properties that allow for great print results.

It features many great properties such as:

• High impact resistance
• High toughness
• Ease of printing
• Wide applications

What many customers love about Siraya Tech Tenacious 3D Printer Resin is that it adds flexibility and a nice weight when being used as an additive to traditional brittle resins.

With this resin, you can produce a wide range of flexible, rubber-like parts. It can be used in applications that require parts with high elasticity and flexibility, such as in the production of wearable devices, toys, and prosthetics.

Some users recommend mixing 1 part of this flexible resin with 4 parts of standard printing resin for the best results. That can make traditional resins less brittle and more flexible.

There is one thing to bear in mind before buying this product. It is only available in clear yellow color. Some users would appreciate seeing more color options, particularly light gray and white.

3. SuperFlex Resin for Hard Flexible Parts

The next resin on the list is the fantastic SuperFlex Resin. It is “Amazon’s Choice” and there are a lot of good reasons for that.

It features many great properties such as:

• Balances softness and strength
• 150-percent elongation at break for shock absorption, cushioning, and damping
• Environmentally-friendly resin
• Suitable for printing miniatures with small details
• Can be mixed with another cheap resin to improve print strength and machinability

One of the main reasons for this resin being “Amazon’s Choice” is the balanced softness with strength. SuperFlex features 80A Shore Hardness. Thanks to 150-percent elongation at break, it is suitable for shock absorption, cushioning, and damping.

Furthermore, this environmentally-friendly resin is compatible with any 3D printer because it uses unique photosensitization technology. Low viscosity allows for high-resolution printing with great precision, meaning you can use it for miniatures with plenty of small details.

Many reviews back up its reputation as an excellent addition to affordable resins when it comes to functional part printing. SuperFlex can do a terrific job of printing minis.

People often use it for miniature functional parts, such as snaps, angles, wheelbases, and levers. These miniatures require both machinability and rigidity at the same time.

I recommend mixing 30% of SuperFlex with another cheap resin. That can make your 3D prints less brittle, so you’d be able to cut threads and drill them without breakage.

While some customers find it expensive, you may get your money’s worth from it in the end. And for many users, it is an exceptional value for the price.

4. RESIONE 3D Printer Resin

Next on this list is the RESIONE 3D Printer Resin. It is manufactured by the RI RESIONE Store, a fairly new company but with great reviews.

It features properties such as:

• Long-lasting toughness
• Super easy to print
• Very low water absorption
• Compatible with many 3D printers

This flexible yet tough resin has received a lot of love and appreciation on Amazon. While the price is certainly one of the top reasons for this (a bottle of 500g costs about $30), there are also many other good things besides the low price point.

When checking out the reviews of this product, many customers said it is a great additive to regular clear resins. The RESIONE 3D Printer Resin has made a significant difference in the flexibility and strength of their minis.

After adding this amazing resin, small parts stopped cracking when they were removing supports. According to reviews, mixing 25% of it with standard resin can do wonders for 3D miniatures.

One user mentioned it works great in his Elegoo Mars, resulting in durable minis. Actually, the durability of miniatures is the top reason why most customers are satisfied with their purchase.

One thing to note about RESIONE 3D Printer Resin is that it tends to separate slightly faster than some other brands. That said, consider shaking the bottle vigorously before pouring it into your vat.

Another thing to note is the odor of this resin. Although the smell is not strong, some users don’t like it. So, it is a good idea to use a window fan while keeping your door closed. That can help you get rid of the smell.

One user recommends keeping the heater on low while working with this resin. The proper temperature can make it easier for it to set. According to the manufacturer, the operating temperature should be anywhere from 68 to 95°F.

While minor complaints exist, this flexible resin is still a great product that many recommend buying.

5. Mika3D Rubber Like TPU-Like Soft 3D Printer Resin

The Mika3D TPU-Like Resin is a great option if you are looking for a soft TPU-like resin.

It features many great properties such as:

• Soft TPU-like resin
• Shore hardness ensures soft prints, especially at temperatures above 68°F (or 20°C)
• Easy to work with
• Good tear strength prevents prints from breaking during stretching and bending
• No harmful chemicals
• Available in different colors, including clear yellow, green, and purple

It features shore hardness which ensures that the prints are quite soft, especially when the temp is above 68°F (or 20°C). To increase the hardness of your prints, you need to reduce the temperature.

There are no harmful chemicals and the bottles are quite easy to pour from. You get three bottles in a single package.

They come in different colors, including clear yellow, green, and purple. Some users say that the colors are somewhat darker than shown in the pictures. To make it clear and glassy, one user sprayed his prints with gloss spray paint and was happy with the result.

In addition to rubber-like performance, many customers appreciate the ease of printing. Users claim that it is very easy to work with. According to one customer, the cure time is roughly 15 minutes, while washing takes about 20 minutes.

Good tear strength prevents prints from breaking during stretching and repeated bending. This is what many people like about the Mika3D Rubber Printer Resin.

There are some complaints, too. Aside from the color of the resulting prints, some customers say that Mika3D is brittle compared to other high-quality ABS resins. Besides, the prints may lack detail and they come out with little muddy details sometimes.

6. Siraya Tech Blu Nylon 3D Printer Resin

Here’s another resin by Siraya Tech that is also worth buying, the Siraya Tech Blu Nylon 3D Printer Resin. This flexible high-resolution resin is available in nylon black only. It comes in a bottle of 1,000 grams.

Here are some of the properties of this UV-curing rapid resin:

• High toughness
• Precise prints
• Wide applications
• Works great as an additive
• Biocompatibility

One of the many things customers love about this resin is its toughness. It is less brittle than most other resins out there and it’s very ABS-like.

Siraya Tech Blu Nylon Resin maintains a fine balance between impact resistance and hardness, which makes it suitable for printing flexible yet strong functional parts. The occasional unintentional drop won’t cause it to break easily.

While there is an odor when working with this resin, the smell is not too harsh according to reviews. Also, the customers say the color looks good unpainted/unfinished.

As for the cons, users say it is messier and sticker than standard resins. Cleaning the resin vat takes a lot of effort and time after printing.

Another complaint is about the softening temperature and some users find the temperature stability pretty low. They also say exposure time is a bit long.

The minimum recommended temperature is 25° (or 77°F). However, at around 50°C (or 122°F), it’s already rubber-like, which could be disappointing. Still, the prints have high strength and are very rigid and they’re dimensionally accurate as well.

So, if you’re looking for a precise high-resolution printing resin that has high toughness, this may be a good choice.

7. Monocure 3D Rapid FLEX100 3D Resin

If you looking for a flexible resin that is suited for low-power UV 3D printers, then you should check out the Monocure 3D Rapid FLEX100 3D Resin. It is developed specifically for LCD/MSLA 3D printers.

It features properties such as:

• High tensile pressure

One of the buyers says he added it to the PLA-like resin, which made his 3D-printed earrings more durable. Another customer claims it helped him improve the flexibility of his standard UV resins that were brittle beforehand.

While most users are satisfied with the quality of their prints, some of them say it smells awful. Even when they were printing with adequate ventilation, the smell was still terrible.

It’s important to keep in mind that this resin may stink up your home and the odor of resin fumes may remain on your clothes for some time. That’s something you should consider before starting to use this resin.

Just be aware that the quality of your prints will compensate for the bad smell. If this is your top concern, then you should consider buying this flexible resin.
