Things to Consider Before Buying TPU Filament
There are different types of materials for making 3D projects. Some of them produce hard models and some produce soft models. Finding the perfect material for flexible and soft 3D applications is not easy. That is why we tried to help you pick the top products from the market. But for different purposes, the characteristics of the best TPU filament may differ. That is why you need to know the main purpose of using it and then have to buy accordingly.
Following are some buying guides that will help to make the right decision.
The flexibility of the application depends on the hardness level of TPU. Every TPU includes a shore hardness number. The more the shore hardness is the more hard the model will come out. For example a Lego block has a maximum shore hardness of near 100A where a marshmallow has only 10A. For getting a medium flexible product pick TPU that has shore hardness of 60A – 70A.
As we all know, TPU filaments include harmful chemicals and working with filaments for a long time can make people sick. And products that are made from harmful chemicals are not safe for children. So if you are buying TPU filaments for making children toys, try to get something that is less harmful. And always try to use full coverage while using TPU.
iii. Model of Printer
Printers are used to make models or applications from TPU filaments. There are printers of several models. Ans not all the filaments are suitable for every printer. Some of the printers require 1.75mm filaments while some of them require 1.25mm filaments. So before making the final decision, see the model of your printer and match this with the TPU filament.
iv. TPE vs TPU Filament?
TPU is new to the market. Before the invention of TPU, TPE was popular for making flexible 3D models. So TPE is also known for sift filament and has been used by many industries for a long time. On the other hand, in a very short time TPU has achieved popularity.
TPE is mainly a non-specific term of soft filaments which does not have too flexible applications. While TPU is a more rigid flexible filament. Compared to TPE, TPU filament provides higher rigidity, which isn’t to be confused with softness or hardness. Rigidity describes how much a material can be bent. showing the characteristics of a material to return to its original shape after being forcefully subjected.
TPE filaments have a wider range of hardness which make it suitable for more hard rubbery products. These are suitable for a car tire, while TPU is very flexible and rubbery and suitable for soft toys, bracelets, bands etc.
Another difference is that a TPU print is heavier than a TPE filament. And the reason is TPU is denser than other filaments. TPU also provides a smooth finish, whereas TPEs have a rubbery texture. Also TPU has a better resistance to abrasion.
v. Is TPU filament toxic?
Though they have a few similar properties like TPU filaments are safe to use. They are non-toxic materials but there are some chemicals that are harmful for the body if you consume it. So TPU filaments should be kept away from any kind of food.
According to some research it is proven that TPU is not toxic and does not harm or damage skin directly. TPU filaments are manufactured by using different types of plastics from nature. Of course these polymers are toxic but when this is mixed with different elements it becomes non toxic.
How to Use TPU Filament?
Using TPU filament is not a hard job but it has some critical techniques. Most challenging part is loading the filament in the printer. But following the steps properly one can easily use this.
Loading TPU is particularly challenging as many printer loading systems run too fast. And it is not easy to handle for flexible soft filament to properly purge. Try to load with a higher temperature than the previous filament requires. Reduce the force requirements to minimize the melting velocity. Try to make a custom Gcode folder that has a slower loading time. Then wait for the printer to heat. After that advance the extruder at a minimal rate for a distance. Then whenever you need to load TPU filament, just print the Gcode file.
Printing without major velocity changes also can help. Use low feed rates and low layer heights so the extruder doesn’t have to change pressure or run fast. It is better to use printers with a less flow rate and on average temperature. So take you time and work with the filaments.
TPU is becoming one of the most desired products for 3D printing for flexible applications. And it is very easy to see why. TPU filaments can be used for different purposes. Anyone can make mobile covers, toys, watch, or anything that requires soft plastics. That requires no heated bed adhesion, wrapping is minimal and the possibilities and uses that TPU filament covers are simply revolutionary.
So, if you are interested in using the 3D print flexible TPU, or you need to print, then what are you looking for? Go and get yourself the best TPU filament roll and start working.
