What to Look for in Softest Filaments

Important criteria

  • Material type
  • Filament diameter consistency
  • Spooling quality
  • Print temperature
  • Bed adhesion properties
  • Tensile strength

1.) Material Quality and Softness

The quality of the material used in the softest filament is paramount. It should be free from impurities and inconsistencies to ensure a smooth printing experience and a soft final product. The material's softness is typically determined by the Shore hardness scale, and filaments with a lower Shore value are softer, making TPU (Thermoplastic Polyurethane) a popular choice for applications requiring flexibility and softness. Before purchasing, check the product specifications for the Shore hardness rating and opt for filaments with a rating suitable for your project.

2.) Brand Reputation and Reviews

It is essential to consider the reputation of the filament brand and the reviews from other users. Established brands often have better quality control and a proven track record of producing reliable, soft filaments. User reviews can provide insight into the filament's performance, its ease of use, and the post-printing softness of objects. Look for filaments with positive feedback on their softness and quality.

3.) Printing Temperature and Machine Compatibility

Different filaments have varying optimal printing temperatures. Purchasing a soft filament that matches your 3D printer's capabilities is crucial. Filaments that require a higher printing temperature than your printer can handle may not print correctly, while those requiring a lower temperature might not achieve the desired softness. Ensure the filament's temperature range is compatible with your printer prior to buying.

4.) Filament Diameter and Tolerance

The filament diameter and tolerance level are critical factors that affect the printing process. Filaments are generally available in two standard diameters, 1.75 mm and 2.85 mm, and your choice should correspond to your printer's specifications. Additionally, a low tolerance level indicates that the filament's diameter is consistent throughout, leading to better print quality and fewer extrusion issues. Therefore, look for filaments with tight tolerances, commonly +/- 0.05 mm or better.

Questions You Might Ask

There are multiple types of 3D printer filaments available, each with different properties and uses. Some of the most common types include PLA (Polylactic Acid), ABS (Acrylonitrile Butadiene Styrene), PETG (Polyethylene Terephthalate Glycol-modified), TPU (Thermoplastic Polyurethane), and Nylon. PLA is biodegradable and user-friendly, ABS is strong and heat-resistant, PETG is durable and has good chemical resistance, TPU is flexible, and Nylon is strong and durable.
You must choose a filament diameter that is compatible with your 3D printer. The most common filament diameters are 1.75mm and 2.85/3.00mm. Check your printer's specifications or manufacturer's recommendations to determine the correct size. Using the wrong diameter can lead to poor print quality and printer damage.
When considering filament quality, look for consistent diameter throughout the spool, minimal moisture content, and good filament winding. Higher quality filaments ensure better print results and lower the risk of printer jams or other issues. It's also wise to check user reviews or seek samples to test before making a bulk purchase.
The color of the filament can affect the appearance of your final print, while its opacity can influence the look of layers and infill. Translucent or clear filaments may show more internal print structure, while opaque filaments provide a more uniform look. Some filaments also have additives like glitter or phosphorescent materials to create specific visual effects.
Not all filaments are suitable for every 3D printer. Printers have different hotend temperature capabilities, bed temperature requirements, and may require specific build surfaces for proper adhesion. Check your printer's maximum temperature settings and compatibility before using a new type of filament, especially if it requires higher temperatures, like some Nylons or Polycarbonates.

How to Choose the Softest Filament for 3D Printing

Embarking on a 3D printing project and aiming for prints with a smooth, soft finish? Selecting the softest filament can be pivotal to your project's success. With the right guidance, you can find the perfect filament that not only brings your creations to life with a gentle touch but also ensures durability and ease-of-use. Let's dive into what makes a filament soft and how to pick the best one for your prints!

Understanding Filament Softness

When we talk about soft filaments, we're typically referring to materials with a certain flexibility and tactile quality. These filaments are often sought after for applications like wearable prints, flexible hinges, or objects meant to have a rubber-like feel. The softness of a filament is determined by its 'Shore Hardness,' which is a measure of the resistance a material has to indentation.
Materials like Thermoplastic Elastomers (TPE) and Thermoplastic Polyurethane (TPU) are well known for their soft properties. TPE is incredibly flexible and can return to its original shape after significant bending or stretching. TPU, on the other hand, adds a touch of rigidity to the flexibility, making it a bit easier to work with in certain 3D printers.
Understanding the level of softness you need for your project is crucial. Consider what the end product will be used for and how much wear and tear it will undergo. This insight will help you choose a filament with the right level of softness that can withstand the intended use while maintaining its shape and feel.

Factors Influencing Soft Filament Performance

Print temperature, speed, and printer calibration play significant roles in the performance of soft filaments. Higher temperatures can make the filament too soft during printing, causing issues like stringing or poor layer adhesion. Lower temperatures can result in incomplete extrusion and weak prints. Therefore, finding the right temperature balance is pivotal.
Printing speed also needs to be adjusted for soft filaments. Slower print speeds tend to yield better results by allowing the filament to properly adhere to the build plate and previous layers. Additionally, ensuring that your printer's extruder is calibrated for soft filament can prevent jams and uneven extrusion, leading to smoother, more consistent prints.
Another critical factor to consider is the compatibility of your 3D printer with soft filament types. Some printers may require specific extruders or modifications to handle the unique characteristics of soft materials. Always check your printer's specifications or consult the manufacturer before attempting to print with a new type of filament.

Purchasing Tips for Soft Filament

With a vast array of soft filament brands and types on the market, it is important to make an informed purchasing decision. Firstly, look at reviews and user experiences for insights on how the filament behaves in practice. A filament may claim to be ultra-soft, but user experiences can reveal its true performance and any potential issues.
Consider the diameter of the filament. Most printers use either 1.75mm or 2.85mm filament, and using the wrong diameter can cause significant printing problems. Also, note the spool's weight and length to ensure you're getting a good amount of material for the price you're paying.
Finally, pay attention to the brand's reputation and customer support. Established brands with good customer support can provide you with valuable assistance if you run into issues. Don't forget to check for the availability of the filament, as well as shipping costs and times, to prevent delays in your printing projects.

Soft Filament Application Examples

Soft filaments are incredibly versatile and can be used in a wide array of applications. One common use is in the creation of flexible phone cases, which can absorb impact and offer a comfortable grip. Soft filaments are also used in making customized wearable items like wristbands or watch straps, providing both comfort and durability.
For the hobbyists and innovators, soft filaments open a world of possibilities in creating parts like RC car tires, flexible joints for robotics, or functional prototypes that require a certain level of elasticity. These materials can also be indispensable for cosplay enthusiasts who need flexible, durable costume elements that can withstand the hustle and bustle of conventions.
When embarking on a project with soft filaments, always consider the end-use to ensure your chosen material meets the required flexibility, durability, and touch. Whether creating practical gadgets or intricate art, the right soft filament can make all the difference in bringing your vision to life with finesse and functionality.
