Question: What To 3D Print With Flexible Filament

Flexible filaments are commonly used for automotive parts, household appliances or medical devices. The filaments are usually soft and elastic and can thus withstand high loads.

What can you make with flexible filament?

Five Easy Print Ideas To Get You Started With Flexible Filament Cable Ties. Custom watch strap. Custom 3D printed shoe sole. 3D printed phone case. Flexible wheel for the Open RC Project.

What flexible materials can be 3D printed?

There are four different types of flexible materials that we are going to look at in-depth in this article. These flexible 3D printing materials are named TPU, TPC, TPA, and Soft PLA. We will start by giving you a brief about Flexible 3D printing material in general.

What should I 3D print with TPU?

TPU has a wide range of applications. For example, it is a good option for 3D printing flexible functional prototypes or end-use parts that need to be bent and compressed. For consumer goods, TPU is ideal for producing accessories, such as phone cases, and footwear components.

Is printing TPU toxic?

Although they have a few similar properties such as TPU and TPE 3D printing filaments are safe to use. They are both non-toxic materials but they should be kept away from food. They don’t wear away easily which means they are very durable printing materials. Both filaments can print objects that should bend or stretch.

Can you 3D print soft rubber?

The good news is that it is possible to 3D print parts with a rubber-like material. In fact, these 3D printing materials are excellent substitutes for rubber. Rubber-like materials are suitable for the production of seals, soft gripe handles or also, for instance, multi-material prototypes that need shock absorption.

What is the difference between PLA and TPU?

In short: PLA is easier to print with, more environmentally friendly and is the go to material for beginners. TPU is for flexible parts that need to be able to return to it’s original state.

Is PLA more flexible than ABS?

PLA is stronger and stiffer than ABS, but poor heat-resistance properties means PLA is mostly a hobbyist material. Enter nylon, a flexible plastic that injects a new set of filament properties into the mix, featuring greater chemical resistance and toughness compared to PLA and ABS, but also reduced strength.

What is the difference between TPU and TPE?

Compared to TPE filament, TPU filament exhibits greater rigidity, which isn’t to be confused with hardness. TPU also has a smooth finish, while TPEs usually have a more rubbery texture. TPU has better resistance to abrasion than most TPEs, and TPU shrinks less than other TPEs.

Can you print TPU on a glass bed?

A glass bed with a glue stick makes a world of difference in adhering prints (especially TPU) to the bed. The EZR Struder is absolutely necessary to print more flexible TPU; if you are printing the stiffer TPU, the stock (or replacement metal) extruder works fine.

What temperature should I print my flexible filaments?

The temperature at which TPU filament will extrude is 220–250 degrees. A heated build platform is not required, but when used the temperature should not be higher than 60 degrees. The extruder system will need to withstand materials that are both flexible and compressible up to a constant temperature of 250 degrees.

Can you print TPU with supports?

Yes, you can print and use supports with TPU filament, but you will need to adjust the support settings in your slicer for good results. People usually recommend printing supports with TPU itself rather than another filament.

How flexible is PETG?

In fact, PETG is flexible enough that it is virtually unbreakable in the layer direction. Excellent layer adhesion translates into improved surface finishes. Low shrinkage means it is often a good choice for printing larger items.

Does TPU filament absorb moisture?

TPU filament is hygroscopic, which means it absorbs moisture from the surrounding air – it is therefore recommended to store the material in a drybox; a (mostly) air tight container with silica gel in to absorb moisture from the air.

Does TPU need ventilation?

Flexible TPU filaments have the ability to adhere well to most surfaces such as glass, aluminum, Kapton tape, and blue painters tape. It is important to always print in a well ventilated room regardless of the filament type.

Is PETG safe to print indoors?

On the contrary, PETG is safer than other 3D printing filaments, such as ABS. The fumes are not toxic, but it’s always best to ventilate your printing room properly. There are some carbon emissions from the fumes when printing with PETG, but experts have concluded that they pose no significant health risks.

Does PLA need ventilation?

When 3D printed, PLA produces sweet-smelling fumes which are laced with UP and VOC. Therefore, ventilation is needed anytime the 3D printing process is initiated.

What is soft PLA?

Soft PLA is a very flexible 3D printing material that feels and acts much like rubber. Great for creating parts that can bend or must flex to fit their environment – stoppers, belts, springs, phone cases, tires, machine parts, kids toys, and more.

Can TPU be used as gasket?

TPU is an elastic thermoplastic material with high abrasion and chemical resistance. Like most elastomers, it’s commonly used for seals, gaskets, and hoses. It can also be found on overmolded plastic parts due to its ability to add grip or dampen vibration.

Is TPU food safe?

FDA Regulatory Status: Some Estane® thermoplastic polyurethane (TPU) compounds are composed of ingredients which are either listed in FDA regulation 21CFR 175.105, 177.1680, 177.1210 and 177.2600 or other applicable regulations, are “”Generally Recognized as Safe”” (GRAS), or are prior sanctioned for use.

Is PLA plastic bendable?

Standard PLA is very rigid and does not bend well, while Soft-Flexible PLA is flexible; its texture is reminiscent of rubber and has a Shore hardness of 92A.

Is PLA or TPU stronger?

Because it’s a little more rigid, TPU objects can stand up to more repetitive contact than those made out of soft PLA. That makes TPU better for things like machine parts. Flexibility: Soft PLA is more flexible. If you need a flexible filament to print anything to wear, soft PLA is the way to go.

Can you print PLA and TPU together?

Yes, TPU can print and stick on top of other materials like PLA, ABS & PETG. Many people have had success combining these two materials within one 3D print. It’s a great way to add a unique and custom feel to your standard PLA 3D prints.
