Rubber 3D Printer Filament Guide – All You Need To Know

ADVERTISEMENT

When it comes to discussing 3D printer filaments, all we can think of is ABS, PLA, TPU, or at the most Nylon. But, there are other filaments in existence as well like, PVA, PETG, Rubber, etc.

Rubber 3D printer filament is an area that is yet not as popular as ABS 3D printer filament or any other, but it exists and is developing at a rapid pace.

People in the 3D printing domain are extremely excited and are doing everything to make Rubber 3D printing as popular as any other. Whether they will succeed or not, only time will say!

Rubber products have their own unique set of demands and markets. Since the inception of manufacturing, rubber has always had a special place in terms of materials used for manufacturing. And this special place is because of the unique characteristics possessed by rubber.

For this reason, after the idea of 3D printing came into existence, researchers were desperate enough to try the idea on various materials, especially Rubber.

But 3D printing with rubber 3D printer filament is not possible. As rubber undergoes vulcanization by external factors for improving its elasticity and strength.

Once Rubber undergoes vulcanization, it can never be reheated, otherwise, it burns. And for this reason, researchers occupied their brains in developing rubber-like 3D printer filaments and resins.

In this article, we will discuss the most common rubber 3D printer filaments that are made of thermoplastic elastomers.

These rubber-like 3D printer filaments have found use in several applications including shoe soles, flip flop as well as sealing rings.

List of Rubber 3D Printer Filament

The Rubber 3D printer filaments that we are going to discuss below have been created after the result of trouble taken by designers, initially experimenting with flexible filaments.

As these filaments are softer to print than the regular ones, they did not print as they were expected to, when subjected to a 3D printer. The pushing string effect of extruders either bent or twisted the flexible filaments.

Ninjatek

This is the brand name given to manufacturing materials made by Fenner Drives, the company that produces specialty materials for end-users in the industrial segment.

Because of its characteristics and unique performance, Ninjatek has achieved tremendous popularity in the 3D printing industry.

Through its polyurethan integration, Ninjatek has unmatched extrusion manufacturing expertise of fifty years in the field.

Currently, on its website, one can get information about:

Printing Guidelines:

  • The recommended extruder temperature range for printing Ninjaflex should be 225 to 235 degrees Celsius.
  • Room temperature in which the printer 3D printing parts and functional prototypes using Ninjaflex is kept should be 40 degrees Celsius.
  • In case your printer does not have a heated bed, you are suggested to use Glue with/without blue painter’s tape.
  • The top and bottom layers’ print speed should be in the range of 10 to 20 millimeters per second. Whereas the infill speed should be in the range of 15 to 35 millimeters per second.
  • You are also recommended to use a cooling fan after two layers of the part or functional prototype have been printed.

NinjaTek has partnered with ColorFabb, a brand active in the business of 3D printing for more than seven years. ColorFabb is a Dutch company that specializes in the development and production of high-end quality 3D filaments. With the help of this partnership, Ninjatek will be able to distribute its range of filament in entire Europe.

Among many types and diameters of filaments, rubber 3D printer filaments in Soft PLA.

Soft PLA: This 3D printer filament acts, and feels much like Rubber. The shore hardness of Soft PLA is 92A. It is one of the most convenient 3D printer filaments for creating parts or functional prototypes that are subjected to bending or flexing when put into applications such as:

  • Stoppers
  • Blets
  • Springs
  • Phone Cases
  • Tires
  • Machine parts
  • Kids toys and a lot more.

Weight: 0.75 kilograms is the standard weight in which this filament is available.

Colors: Black, White, Red, Blue, Silver, Lime Green, as well as Beige.

Printing Guidelines:

  • Sticks to the print bed that is layered with blue painter’s tape.
  • MatterHackers recommend a slower speed than the one used for manufacturing normal PLA.
  • The recommended extruder temperature range for printing this rubber 3D printer filament is 220 to 235 degrees Celsius.

After seeing the examples of the parts and functional prototypes manufactured from this 3D printing material, you can judge for yourself, how functional this rubber 3D printer filament is. All these parts and functional prototypes have been tested and approved by its in-house team.

Apart from having a fantastic technical team, the company also has a wonderful customer service team that helps you with anything you may need. Be it finding the right machine for packaging your specific product, to discussing which filament is best for your application.

Taulman

Taulman PCTPE

There are twelve 3D printer filaments that one can find on Taulman’s website. The one that is rubber 3D printer filament is titled PCTPE.

PCTPE: 

TPE is something anyone in the field of the 3D printing industry can relate to. PC stands for plasticized copolyamide. This complexly named material is a chemical co-polymer of highly flexible nylon and TPE. This 3D printer filament has some unique features that allow users to print even highly flexible parts or functional prototypes with ease.

It allows any FFF 3D printer to print parts from the durable prosthesis to completely wearable outfits, as well as cell phone closures and highly flexible industrial parts and functional prototypes.

The end parts printed using PCTPE possess the smooth lustrous texture of Nylon added with the flexibility of rubber-like TPE.

But while giving a part all of these, the filament does not compromise on durability as well as non-delaminating benefits.

The shore hardness of this 3D printer filament is estimated to be around 100A.

The diameter of the filament: PCTPE is available in 1.75 as well as 2.85 mm.

Color: Natural and Black

Printing Guidelines:

  • The printing temperature range that is considered safe for PCTPE is 235 to 242 degrees Celsius.
  • For achieving low shrinkage on parts and functional prototypes, one should consider printing this filament on glass with a fifty percent water or PVA glaze heated up to 40 degrees Celsius.
  • PCTPE can be printed using the Bowden as well as the direct drive extruder.
  • All the parts and functional prototypes printed using PCTPE are bound to have a super layer to layer bonding allowing single perimeter walls folded along the thread axis.

This rubber 3D printer filament is also used in manufacturing cell phone covers and cosplay wearables that can be made with FDM 3D printers.

To 3D print rubber and to 3D print PCTPE is almost similar as it has high durability and a smooth texture that is nylon-like.

Typically, you can use PCTPE for printing parts and functional prototypes that have similar to or more flexible characteristics than Nylon.

It is also quicker and easier to print with this rubber 3D printer filament as it is less elastic than TPE.

  • The heating bed of the printer is recommended to stay in the temperature range of 90 to 110 degrees Celsius while 3D printing a part or functional prototype.
  • Your printer’s print speed should be at a lower level for getting an exact geometry of the part or functional prototype as per the 3D design file.
  • The fan’s speed should be 50 to 100 percent than it’s efficient to rotate.

The Conclusion

You can achieve a rubber-like feel on 3D prints manufactured for the filaments mentioned above.

Even after getting any of these rubber 3D printer filaments, it is necessary for you to get the printer settings right.

Otherwise, the cost of buying anyone of these 3D printer filaments will not convert into something fruitful.

Additionally, you would end up wasting your time and not meet the project deadline. So, be careful because these are all flexible filaments.

The above-mentioned filaments are the rubber 3D printer filaments. They are manufactured by different brands and are available in the market on their own terms and prices.

If you have a 3D printer and wish to experiment with making parts and functional prototypes that depict rubber, you would’ve to buy them and take care of the printing guidelines mentioned above.

Rubber being a really sensitive material, the guidelines should be strictly followed. Otherwise, it could lead to print failure and if not taken care of, the parts or functional prototypes manufactured can fail when subjected to application.
