Introduce NEXTFILA

Construction of a prototype is not only for technological products, but can also be for various patents and tangible ideas for a variety of forms prior to mass production.
In this way, many entrepreneurs in various fields can take their idea as a prototype to groups of investors and raise money for the project, and create partnerships with production companies and many other useful actions.
In the past, one needed to seek the services of special commercial companies to build a prototype, one with professionals that can interpret your idea, create a graphic design and then print it in three dimensions using a special printer that works with the 3D method for printing the prototype.
Because the costs to print of prototype are considered expensive, in recent years special printers have been developed for professional use by private consumers at prices that meet their needs.
Today, there are three types of 3D printers tailored to the end consumer that can print a prototype for any use, whether it's a manufacturing technology product, patented, electronic device or anything else.
The most popular 3D printer that works on technology is FFF. Although this type of printer is considered new in the market, it is gaining momentum due to the fact that it uses relatively inexpensive materials for production of a prototype. Let's look at what is happening in the market and understand the main problem encountered when printing a prototype with the 3D printer.

Biggest problems with 3D printing

Currently there are bobbins of filament suitable for use in 3D printers. The common denominator among them is that you can use only one end of the filament and need to thread on the head of the printer and work with it to the point where the bobbin ends and a new bobbin needs to be replaced. This sometimes occurs in the middle of the printing process and creates significant economic loss. The other end of the wire coil is hidden and cannot be accessed in order to make a connection between the two wires to continue the printing operation, creating significant damage and many losses for printers worldwide. By using the new bobbin of our company, NEXTFILA, you can access the second end of the filament of the bobbin and plug it at any stage of the printing process using a specially developed welder. This is done at minimal cost, thereby ensuring quality work, operation flow and significant savings of time and money.

- wasted remaining filaments

- Vacantly wait until the old filaments to be all consumed to change filaments.

- Printing failure will occur because of shortage of the filament.



This problem will be solved, if you can connect the old filament to the new one in advance.

NEXTFILA® : The world's first connectable filament

NEXTFILA is the world's first connectable filament. You can simply connect a new filament to the remaining filament while printing without stopping your 3D printer.


This can be achieved without a highly complex mechanism.
NEXTFILA' filament is wound to our specially-designed bobbin, which makes filaments' connection possible.
You can connect your remaining filaments to the new one using a special filament welder.
After all of remaining filament is consumed, the joint filament will naturally follow through the gap and the new filament will start to be consumed.

Try use NEXTFILA filament.
It enables you to work with 3D printer using endless filaments, and it is even possible without any printer modification and additional cost.

♦ You can save your money and save the environment because there is no wastage of filament. You can completelyuse the filament to the end.
♦ You can save your time because you can connect a new filament to theremaining filament at any time you want without stopping your printing job.
♦ You would have no printing failure due to a lack of filament.

You can use all of these advantages just by changing your filament to a NEXTFILA filament without an additional cost.


How to use


An example of filaments connecting work. Koean. English Subtitles.

A way of connecting filaments is simple. You can connect filaments without stopping a printing job.

Step 1. Pull out a filament that you are using(a residual filament). If your printer can adjust printing speed, reducing the speed would be helpful.

Step 2. Cut a begging of a residual filament that is winded to a extra flange.

Step 3. Assemble a residual filament and new filament using bolt and nut. The bolt and nut's STL files can be downloaded from NEXTFILA home page. There are several size of bolts and nuts. You can choice one of them.

Step 4. Connect two ends of the filaments using a filament welder. If you don't have a welder, you can buy a simple and cheap welder made by NEXTFILA.

Step 5. Wind remaining filament to a bobbin by turning two bobbins clockwise relatively.

Step 6. Done.


Product Size


Check the size of a bobbin assembly. Refer to the upper diagram whether you can use NEXTFILA filament to your printer or not.
(The bobbin's diameter is 200mm(7.87in), and the width across two bobbin assembly is 86mm(3.39in). A filament holder size of your printer has to be bigger than these sizes.)
If the assembly size is bigger than your printer holder, you might need an extra filament holder.
If you want to use a thick head bolt and nut, the total assembly width will be 108mm. Check your printer holder width.

Filament Welder



A filament welder is needed to use a NEXTFILA filament. Therefore, we have developed a special filament welder. This welder has very simple structure to achieve an economic price. It doesn't have a heater, a temperature sensor, a temperature controller and a power supply.
Please read this to check the possibility.


Development History


Gwacheon National Science Museum in Republic of Korea

Several types of 3D printed test bobbins

testing...

We have proceeded with a connectable filament development acquiring a patent since Oct. 2014 to solve several 3D printing problems.
A shape of a NEXTFILA bobbin was tested using 3D printer with the help of Fablab of the Gwacheon National Science Museum in Republic of Korea and, the design was finalized in Dec. 2015.


There are many size of bolts and nuts(to assemble two of NEXTFILA filaments) STL files in NEXTFILA web site. Download STL files as your choice and print to use. The shapes of these bolts and nuts are being tested using a 3D printer for many cases.


The NEXTFILA filament can
Save your money,
Save your time,
Save the earth.
 

NEXTFILA® is the world's first connectable 3D printer filament.
Use a whole filament completely without a remaining filament waste, No stress for waiting to change a filament even in night time or holiday, No stress for printing failure due to unexpected filament shortage when you are printing.
