  • 2.85mm?
    A message to all our 3mm eSUN filament customers that might be asking where their beloved 3mm filament has gone. The reason for the change is because while a lot of machines do take 3mm filament, some machines require the slightly smaller 2.85mm filament. Since 3mm machines work just fine with 2.85mm, manufacturers are generally starting to opt for the more versatile 2.85mm filament.

    What changes will I need to make from 3mm?
    On your machine, the move from 3mm to 2.85mm only takes 15 seconds. All that is needed is one quick slicer setting change. Simply adjust your filament diameter from 3mm to 2.85mm and you will be up and printing immediately. If your slicer does not have the option to change this setting for some reason, simply adjust your extrusion multiplier by a factor of 0.95.

    Happy printing!

    eSUN Colour Change by Temperature PLA:
    Within seconds of exposure to cool air eSUN's thermochromic PLA will begin to change colour from the outside first. This gives the 3d printed object a varied colour every time it changes colour. Extremities change colour first... it looks fantastic!

    For optimum versatility eSUN has designed the median temperature of their filament to be around 25°C and has a large colour change from just ±10°C. This means that it's very easy to manipulate the colour at home. What will you print with thermochromic filament?
    This video shows the very fast colour change when a thermochromic 3d printed object is submerged in temperature changing water.

    Nerd Speak:
    The term thermochromism is used to describe the phenomenon of a reversible chemical transition that greatly affects the electromagnetic absorption in the visible part of the electromagnetic spectrum of an object, when that object is exposed to varied intensities of heat. In English, thermochromism is when a material undergoes reversible changes in it's colour when exposed to varying termperatures. Thermochromic materials began to emerge from the laboratory in the 1960's. Today, thermochromic additives are widely used across the world including in manufacturing, process control, security printing and novelty items.
    Quality matters. eSUN Industrial is an international leader in FDM inovative technologies and their filament is a testament to their dedication to quality.

    Diameter Consistency:
    It's important that your filament has a very constant diameter if you want to get a great looking print. Variance in filament diameter will result in poor surface quality (primarily on vertical sections), because it produces unwarranted and uncontrollable fluctuations in extrusion rates.

    eSUN promises that their filament has a tolerance of ±0.05mm across all of their rolls that they produce, but in reality, the quality of eSUN's filament far exceeds their listed specifications.

    One independent reviewer found that the "vast majority" of the eSUN filament they tested in fact had a tolerance of ±0.015mm! Additionally, premium looking prints made with eSUN filaments (like what's found in our gallery) authenticate the claims of many that eSUN produces very consistent filament.

    You can be confident that your prints will have fantastic surface uniformity and smoothness with eSUN.
