The SainSmart Flexible TPU 3D Printer Filament ($29.99) can be used to create prototypes. It has a rubbery texture, and is more flexible than ABS and PLA, making it especially suitable for 3D printers. This filament has a diameter of 1.75 millimeters, variations of ± 0.05 millimeter and roundness of ± 0.05 millimeters.

This highly flexible and elastic filament is great for making prototypes of flexible objects, as it lets you demonstrate the elasticity of the object with the prototype. With variations that small, you can guess how this filament’s low rate of shrinkage makes it great for storage over a period and still good for use when next you need it.

3D printing is a precision-sensitive process, and this high-precision plastic filament delivers the professional outcome you desire. The 2.2-pound spool has a wide core that can be automatically fed to the 3D printer, to prevent tight coiling of the filament. This filament has an accuracy of 1.7-1.8 millimeters, which is good as far as 3D printer filaments are concerned.

This SainSmart filament comes in nine different colors.

IC3D is a 3D printer manufacturing company. It was the first to manufacture its own line of 3D printing filaments, as it realized that the filament from other industries, such as plastic welding, was not producing the type of output it required. It then recognized the need for a new material with properties made especially for 3D printing machines. Its manufacturing process, combined with its expertise and focus, provide some of the highest-quality filaments at affordable prices.

The IC3D ABS 3D Printer Filament (Suggested Retail Price: $34.99) is a 3-millimeter ABS filament that is compatible with most 3D printers. It has a diameter of 2.9 millimeters +/-0.1 and roundness of within 4%. Each hand-checked spool weighs 2.1 pounds, with an accuracy of +/-0.5 millimeters. It is vacuum-sealed with desiccant to avoid moisture absorption. It has also been extensively tested on various 3D printers, utilizing several extruder designs and hot-end styles.

Here are some other great filaments made by IC3D:

Hatchbox offers an extensive collection of 3D filaments that cater to numerous applications (suitable for home, business or just playful creativity). Its outstanding craftsmanship makes it unique and puts it at the forefront of the 3D printing race. For consistency in quality, variety in selection and affordability in pricing, Hatchbox has carved a niche for itself in the 3D printing world.

The Hatchbox Yellow PETG 3D Printer Filament ($22.99) is a great alternative to ABS or PLA filaments. The easy adhesion quality it possesses makes it unnecessary to use a heated bed. It can be printed on acrylic, glass, polyimide tape, or blue tape. This filament is also great for printing lightweight objects because of its durability. It has a 1.75-millimeter diameter, with a +/- 0.05-millimeter tolerance. The spool weighs a total of 2.2 pounds. The recommended extrusion temperature is 240°C-260°C.

This filament is hydrophobic; it does not absorb moisture. This makes it relatively easy to store, as you don’t have to look for any special storage system to ensure it stays dry. This is one major advantage of using a PETG filament for your 3D printing projects. Some other types of the filament will produce a smell when heated. This filament is odorless, avoiding any allergy issues for sensitive users.

A heated bed is not compulsory when printing with PETG, but it can be an advantage, especially when printing large pieces. PETG is considered to be food safe in many countries (no, not edible! You can’t eat it). You can print items to use with your food and drinks, but we still advise that you check the manufacturer’s specifications. It is also environmentally friendly and can be easily recycled.
