Adding PETG to the list of Ultimaker materials


Recommended Posts

Posted · Adding PETG to the list of Ultimaker materials

Hi! 

 

We’re proud to announce that we’re adding PETG to our list of materials, along with the print profiles for optimal print results. PETG is not just any material, we think it has the capabilities and specifications to become the new go-to material. An honor that belonged to (Tough) PLA for a long time. 

 

Available in a variety of colors, including transparent, translucent and fluorescent, it’s perfectly suited for a wide range of applications, thanks it’s properties like good printablility, toughness, chemical resistance, wear resistance and temperature resistance. 

 

 

Why would you use Ultimaker PETG?
 

  • It’s for anyone – novice or expert. Ultimaker PETG is one of the easiest-to-use 3D printing materials on the market. With good adhesion and print profiles – including engineering intent profiles – anyone can quickly and easily start 3D printing with Ultimaker PETG 
  • It enables you to unlock the widest range of technical applications. Compared to PLA and Tough PLA, Ultimaker PETG unlocks the widest range of technical applications, offering the printability of PLA, but with the industrial properties you need. This enables you to create a wide range of industrial parts, tools, and prototypes. Ultimaker PETG offers the ideal balance of properties for Ultimaker users in industrial environments, with good all-around visual, functional, and mechanical properties that can withstand environmental influences such as wear, chemicals, and warmer temperatures 
  • It sets the standard for enterprise-grade, industrial use. Ultimaker PETG is one of the most affordable technical 3D printing materials. It is also perfectly suited for different industrial environments – versatile, safe, easy to print, and available in many colors. Together, this makes Ultimaker PETG easy to deploy across your organization – meaning fewer changeovers and increased standardization

    Great presentation.

    But I have to ask this question: What is the main difference between PETG and CPE from Ultimaker?

    What are the differences that I should keep in mind to make the decision on what material to choose?

     

    From what I can see PETG can handle a slightly higher temperature (70°C for CPE, 76°C for PETG; based on the data sheets), has some more colours to offer and is just a couple of euros cheaper.

     

    I often read that CPE is Ultimakers PETG. That's why I have to ask 🙂

    UM3 will not print with PETG ?

    Yes it will, no problems at all but I reccomend you print on PEI sheet, and on a flex plate, or order lots of spare glassplates. The adhesion of PETG is so strong it easily chips glass when cooling down.

     

    What Ultimaker is announcing is ready optimised profiles for their PETG, you simply have to make your own for your printer.

    Hi @Gero, great question! So great, we actually covered it in a support article 🙂  The article might be best summarised using the last paragraph:

     

    "Unless you require the specific chemical resistance of CPE, it is very likely that you would prefer to use PETG instead. You will benefit from improved printability, while retaining or exceeding the mechanical properties of the printed part." 

     

    Make sure to read the article if you want to know more!

    Hoi Sander,

     

    I would be interested, but I have a few questions:

    - Can this PETG be smoothed with dichloromethane too? How well does that work?

    - How transparent can you get parts, with which optimised settings?

    - How is UV-resistance, when sitting outside in the sunlight?

    - Over time, does printing with this PETG accumulate dirt in the printer-nozzle? The brand of PET that I use now, does leave a sort of glossy varnish coating in the nozzle, which is hard to remove. Contrary to PLA that rather leaves powder-like ashes that easily come off.

    - When parts fracture at overload, how does that go? Following layer lines, or going diagonally through all lines; and with or without warning (whitening, microcracks, permanent deformation)? The brand I have now, fractures without any warning, no whitening, no permanent deformation prior to the failure.

     

    Could you post a few photos of these aspects? See these pics below for comparison.

     

    Transparency tests with another brand of PET: top row printed at 50mm/s, bottom row at 10mm/s; layer thickness from left to right (mm): 0.4; 0.3; 0.2; 0.1; 0.06. At 10mm/s and thin layers, browning begins to occur, due to sitting long in the nozzle, even at reduced temperature. These blocks are 20mm x 10mm x 10mm, with my hollow watermark sitting halfway.

    Other PET-brand: snaps diagonally through layers at overload. See the radial pattern. No warning, no whitening, no deformation prior to failure.

    Other PET-brand: one item smoothed with dichloromethane, the other is as-printed.

    Hi @geert_2, thanks. Great questions! Unfortunately I don't know the answers by heart but I've shared them with our product experts and will let you know when I hear back.
