The world of 3D Printing is truly an exciting one, with constant improvements happening from day to day relating to both printing components and machines, as well as the 3D Consumables that these machines use to fabricate various models, tools and parts. One such exciting development is the new eSUN ePA-GF Filament, stocked for 1.75mm compatible printers and reinforced with real glass fibres to give it extra strength while still maintaining relatively impressive flexibility.

This filament is Nylon-based, and is coloured beige, with a slight translucency that gives it an almost glass-like aesthetic. This combination of materials and visual aesthetics makes for a very Unique Filament that not only looks good, but is also incredibly durable and capable of withstanding impressive forces without permanent damage. This offers the same kinds of benefits of Nylon and Carbon Fiber Filament, but also adds the extra benefits of increased creep resistance, as well as fatigue and heat resistance at temperatures up to 120°C, resulting in a strong filament that will maintain proper shape during and after printing, with substantially less deformation and shrinkage compared to typical Nylon Filaments.

Extra Notes and Precautions for Printing eSUN 1.75mm ePA-GF Filament:

With eSUN’s glass fibre filament being such a unique polymer comprised of multiple different materials, there are a few extra notes that you should keep in mind before and while printing. They are relatively simple, but quite important in order to enjoy the best results and as little wasted time and money as possible. They are as follows:

  • The first factor is this filament is very abrasive, and will very quickly wear down brass and aluminium nozzles, making stainless steel or carbon steel nozzles a critical component to avoid clogs and bad extrusion quality.
  • The second factor is that this filament is best printed within an enclosure, but without a part cooling fan, so as to ensure optimal layer adhesion.
  • The third factor is that you need to ensure a nozzle distance from the bed of between 0.2mm and 0.3mm, as any lower than 0.2mm will result in the glass fibres not being laid properly, and instead just getting in the way and clogging the end of the nozzle.
  • Finally, the fourth factor to keep in mind is that, while this filament has been designed to offer a smooth finish after printing, it’s a good idea to polish up the finished print in order to shave down any small glass fibres that may be poking out – just to avoid any scratches or cuts when handling it.

Despite these important factors, eSUN’s ePA-GF Filament is an amazing material to print with, and produces surprisingly strong parts with little shrinkage and warping, as well as maximum strength and durability.

eSUN ePA-GF Filament - 1.75mm Glass Fibre Reinforced

Shenzhen eSUN Industrial Co., Ltd was established in 2002 in Shenzhen Special Economic Zone and has rapidly become one of the leading international suppliers of 3D Printing Filament. They specialise in research, development and production of degradable polymer materials, and have grown their catalogue of filaments to include PLA, ABS, PC, PVA, and a wide range of other polymers and copolymers.

Their list of exclusive filament formulas include unique materials like wood, aluminium, bronze and other materials to create highly specialised filaments that can stretch, bend, be moulded or otherwise behave in very unique ways. Their filaments are also commonly characterised by their absolutely round shape, extremely low diameter tolerance, uniform colours and impressively stable melting points. These characteristics, in combination with their long-term insistent policy of “Best Quality, Reasonable Price” has garnered them a large share of the market, with their reputation commonly preceding them within knowledgeable online and offline 3D Printing communities.

eSUN’s popularity in the industry has also helped to produce sustainable partnerships with many internationally famous 3D Printer manufacturers and distributors, with DIYElectronics having sole distributorship rights to provide their 3D Printing Filaments to South Africa and neighbouring African countries.
