March Update #2 : Special Filament and More

Posted by FLUX Technology LLC (Creator)

Hello backers!

Today we are going to share some test results we have done in the past month and provide some information about our current progress. In this update, you will first see the demonstration of how Flux handles several special filaments and what parameter or procedure we used to print; then you will see our recent progress.

Special filaments

In this section, you will see some test we’ve conducted in the past month. Since Flux is still in development, many parts still have the chances to be refined and printing parameters is not yet optimized to its best, these results are just demonstrations of how versatile Flux can be. The prints you see in this update do not represent the printing quality of the final product.

In each category, we will show the parameter we used when printing the model along with an brief introduction and our thoughts about the filament. If it needs any special treatment to print, it will also be stated clearly. Every filament is used to print the same model in order to compare them easily.
Thanks Mahoney for generously providing the model Mr. Jaws at ! The size of the print is modified to 62 x 22 x7.5 mm.

1. Wood PLA

Printing temperature 210 degrees Celsius
Printing speed 50 mm/s

We have tested two kinds of wood-like PLA, the lighter one contains no natural material and the darker one has 40% of real wood composite.

The first filament contains no real wood, and it mimics wood appearance from its foamed structure. The print made by this filament is light and has rough surface that looks like balsa from the appearance. Another filament is a mixture of 40% grinded coconut particles and PLA. It not only has the look of real wood, but also has the smell of it. You can also see noticeable coconut particles. Both filaments are really easy to print, but they are light and fragile. These wood-like filaments are good for household usage. 

2. Metal PLA

Printing temperature 200 degrees Celsius
Printing speed 50 mm/s 

The manufacturer of this PLA claims that copper powder is added into this filament, and its shimmering color resembles the reflection metal surface. It is easy to print, odor-free and looks gorgeous to fit with jewelries!

3. Luminous PLA

Printing temperature 200 degrees Celsius
Printing speed 50 mm/s 

Glooming in dark, this filament can be used to print those stars hanging in your bedroom. It can absorb the light and emit warm green light, and the more light it absorbed the lighter it will be in the dark.

4. Photochromic PLA

Printing temperature 200 degrees Celsius
Printing speed 50 mm/s

Need a warning when UV light is too strong? This filament changes from translucent to purple in seconds when exposed to UV light. You can easily made this into a bracelet or necklace and bring it with you!

5. Thermocromic PLA

Printing temperature 200 degrees Celsius
Printing Speed 50mm/s 

Depending on the composition, this kind of filaments change its color to white at a defined temperature. We have tried two with different transforming temperature, the pink one changes at 31 degrees Celsius and the black one transforms at 38 degrees Celsius. 

6. Nylon filament

Printing temperature 245 degrees Celsius
Printing Speed 50mm/s 

Nylon filament is an extremely strong and durable material. The one we’ve tried is also highly transparent and lighter than PLA / ABS print. Another interesting property of this filament is that it is slippery, which makes the material suitable for making gears or movable joint. For casual application, nylon can be colored by nylon-compatible dyes. 

To print this filament, be sure to pump up the printing temperature to over 240 degrees Celsius. The terrific thread-to-thread bonding property can easily makes the print surface really smooth and strong under appropriate conditions. 

7. Extra strength PLA

Printing temperature 210 degrees Celsius
Printing Speed 50mm/s 

Normal PLA usually has low mechanical strength compared with ABS. However by implementing special nanostructure, this extra strength PLA can be even stronger than ABS! Furthermore, though it is so tough, it is completely compatible with the 3D printer that uses PLA or ABS. The awesome property allows prints made by this filament machinable and has much more possibility for further application. The following gif shows the mechanical strength of this filament.

8. Flexible PLA

Printing temperature 215 degrees Celsius
Printing Speed 25mm/s 

Sometimes you have to be soft to conquer the most unyielding. This filament creates flexible, yet strong prints. You can easily think of so many utilization of it, such as anti-vibration mounting, pieces that need to withstand pressure or even just for fun! 

To print with flexible material smoothly, remember the following points. Since it is flexible, you cannot print it with high speed in case it bends before the bowden tube. Also because it is relatively soft and tends to drop without support, we do not recommend to use this filament to print models with too much overhang.

This is such a fun filament that can bring more possibilities to your Flux, and we will keep trying more flexible filament to find the best one for you!

9. ABS

Printing temperature 230 degrees Celsius
Printing Speed 50mm/s

ABS is a common material used in 3D printing, yet we don’t recommend using it since it emits poisonous gas and has strong odor when printing. Also, the strengthened PLA mentioned above is even stronger, which can take the place if you need a machinable print. However, Flux is able to print the ABS without heated bed, only with an easy treatment beforehand. Below we will explain how to use ABS juice to print ABS on a non-heated bed.

Prepare a glass jar which is airtight. Pour pure acetone in it and mix with some ABS filament you want to print, the weight ratio is about 3:1. Wait for at least 24 hours for ABS to completely dissolve. Before printing, use a brush to put some ABS juice on the printing bed, then print without raft. Now you can get a print without any warp!


There are still many interesting filaments out there, including carbon fiber filament, conducting filament, etc. We will keep trying them to introduce all of the exciting new possibility disclosed by brilliant manufacturers to all of you, and also test the durability of Flux.

Thanks for Esun, Golden Dolphin, NinjaFlex, and Polymakr (arranged in alphabetical order) for providing sample for us to try on Flux at the TCT + Personalize Asia expo. Also some of the testing filaments are purchased from


Production progress

1. Hardware

We are almost done with the mass-production DFM and have begun to build beta samples to test the function. Few samples were already made but they were not final design so we decided not to show them. If everything goes well, we planned to have an in-depth introduction of the final build in our next update in mid-April.

2. Software

We have recruited experienced UI/UX engineers to help us improve the operation flow and interface of Flux Studio. The beta version will be showed in mid-May to demonstrate the intuitive control. We have also massively improved the scanning quality by changing the design of laser and improving the algorithm. Detailed update will be released in the end of April. 

3. Logistics

We are now talking to different distributors and warehouses worldwide simultaneously. We are trying our best to find the best logistics plan for everyone. More information about logistics will be announced as soon as possible once we have made our decision.


Social media

As we stated in our last update, we are now working on linking all communities together to deliver a more complete experience. The first step is to post regularly on our Facebook fan page to tell everybody what we are doing lately, and we have already posted 7 posts since the last update, hope all of you have seen them! Next week we will be sending our first official newsletter, which can be subscribed on our official website. Here’s what you can expect to see: 

1. The condensed version of our Kickstarter update.
2. What we would like to share with you, such as the production progress, our daily life, or something we make that we think worth sharing.
3. Cool or interesting project, print, or news shared by YOU! 

The third part will be interesting or informative posts we choose from the Flux forum. So don’t hesitate to share anything you think is noteworthy on Flux forum

Also we apologized for the inconvenience that if you have subscribed during the Kickstarter campaign you will have to re-subscribe on our official website to receive the newsletter. This is because the mail system we used previously has several issues that caused some of the subscribers cannot receive our email, and some of the emails sent turned out to be all gibberish. Thus we have to switch to another system to resolve these problem, and we are really sorry if this causes you any trouble.


Thank you for your support, we are trying our best to improve every aspect of Flux. If you have any suggestions please let us know immediately so we can be better! See you in the next update!

      +1 for information about ordering the filaments demonstrated. Either here or on the flux forums.

    5. Sid Blonde on

      Please provide more information on filaments tested, such as manufacturer (where to obtain). I imagine this data will be compiled in some sort of guide; perhaps to ship with the printer?
      Keep up the good work! :)

      I didn't even know all these filaments existed!
      I cannot explain how excited I am, and how awesome those sharks look!
      Thank you!! :D
