3D Printing Tips For PLA/TPU/PETG Filament

What is PLA Filament?

PLA, also known as polylactic acid or polylactide, is a vegetable-based plastic product, which generally uses cornstarch as basic material. ... PLA is a completely eco-friendly polycarbonate polymer including eco-friendly basic materials. Among all 3D printing materials , PLA belongs to one of the most prominent materials utilized for additive production.

PLA Print Settings (Tips) Recommended

1.PLA filament prints well at temperatures of about 195-215°c. Don't leave PLA heated for too long as it will degrade and affect your print.

2.The recommended bed temperature for PLA is 50-60°C.

3.Remember to keep the PLA always dry enough to print, otherwise, it will affect the printing precision.

4.PLA filament isn't as picky as other filaments when it comes to cooling however cooling down too rapidly is still a poor concept. We advise still disabling any cooling down for the first 2 or three players of the print. This will certainly help bed adhesion and also ensure that the rest of your print will be standing on some rather strong footing.

5.PLA Print Speed: Setting the print speed needs to take into account the temperature you're publishing with and also the thickness of your filament. A thicker filament will take longer to warm up, as well as thus requires to be published slower.

If you set your printing temperature level a little on the high side of the acceptable array, after that you can probably escape greater printing rates as well.

A series of 30 mm/sec to 90 mm/sec is usually advised for PLA. This is an extremely vast array and also you'll require to exercise your profundity to balance print rate with printing temperature.

What is TPU Filament?

Thermoplastic Polyurethane (TPU product) is a flexible, abrasion-resistant thermoplastic. TPU filament is abrasion immune, can stand up to influences as well as is immune to numerous chemicals. ... Its functional as well as utilized in many different markets.

TPU is regularly used in wheel wheels, lorry cockpit console, sporting products, power devices, scientific devices, shoes, drive belts, blow up boatings, and likewise a variety of extruded movie as well as also sheet applications.

TPU is furthermore a great product to be used in the outside situations of mobile phones such as tablet computer computers as well as phones.

TPU Print Settings (Tips) Recommended

1.The advised extrusion temperature array is in between 225-250 ° C relying on the type of 3D printer and also a TPU filament you have. Nevertheless, bear in mind that printing with higher temperatures will certainly allow the filament to thaw faster and to stream easier from a nozzle.

2.TPU filament typically prints best at slower speeds. It is a good practice to set half of the average speed (15 mm/s – 20 mm/s) to ensure high-quality prints.

3.Type of the extruder: Direct Drive extruder is recommended

4.Heated print bed: 50 ±10 °C

5. Cooling: part cooling fan is recommended (medium or high setting)

6.Enclosure: not necessary

7.Recommended Build Surface: Kapton tape (PEI), tempered glass bed, the flexible magnetic build plate is not recommended.

8.Retraction is the system in a 3D printer, which pulls the filament backward into the extruder as a way of avoiding the oozing of the melted filament. This feature is very valuable with stiff filaments like PLA and also ABS.

Nonetheless, with TPU filaments , retractions can be tough and also can result in blocking. That's why it is very a good idea to disable retraction to avoid stretching and also pressing of the versatile filament in the nozzle.

9.A raft is an offhand horizontal surface in addition to which a part is printed, and it is utilized to prevent bending. However, because TPU parts generally do not warp, the raft is not advised when 3D printing with TPU, not a minimum printing of since they can cause additional printing issues due to high printing rates.

On the other hand, it would certainly be smart to print with a skirt-- a couple of loopholes of product around the print-- to check the flow of the filament as well as ensure the success of the initial few layers.

What is PETG Filament?

PETG filament is another kind of 3D print material stronger than PLA filament. This is an extremely high toughness filament as well as can achieve really sturdy and also solid prints. PETG is made from Polyethylene Terephthalate (PET) enhanced with glycol (hence the letter G after PET).

It has extremely reduced shrinkage, making this perfect for bigger flat surfaces. PETG is an excellent choice to ABDOMINAL and PLA, offering higher stamina, reduced shrinkage, and also a smoother finish.

PETG filament

PETG Print Settings (Tips) Recommended

1. PETG filament has a greater melting temperature level than PLA so we recommend establishing your hot-end temperature level in between 235 and 250 ° C.

2. ALWAYS make use of a fan with PETG as it tends to cool down the filament in the hot end as well as assist with retractions.

3. Keep your retraction rate sluggish at 40mm/s or much less.

4. Establish your bed temperature level to 80-100 ° C.

5. Keep in mind that PETG can not be printed on a versatile magnetic build plate, due to the fact that PETG filament requires a higher bed and also nozzle temperature level, it will damage the build plate, while at the same time, can not stick effectively on the plate.

it is recommended to better to print on the PEI build plate or tempered glass bed.

6.It is also recommended to print with a skirt-- a couple of loopholes of product around the print-- to check the flow of the filament as well as ensure the success of the initial few layers.

In Conclusion, most people like to print with PLA filament on a DIY 3d printer with a Bowden extruder system while print TPU/PETG Filament on a direct drive 3d printer, basically TPU and PETG will be much more difficult to print out than PLA filament, but only when you set with the correct settings, all will come out with a good result.

2021 Latest released Tycoon direct drive 3d printer really can print PLA/PLA/PETG filament with good results. this is a new X linear rail 3d printer come features all the functions it needs with industry precision. Will you like to try?

    For TPU, build plate should be: PEI or glass. Not flexible magnetic.
