JSR 1:10 Off Road Shock Protectors

JSR 3D printed shock protectors

We are pleased to announce the release of our new JSR 1:10 Off Road Shock Protectors. These are 3D Printed in Semiflex from Fenner Drives, the makers of Ninjaflex, on a P3 Steel at 0.2mm layer height with a speed of 15mm/s. Initial versions of the covers were printed in PLA first, then PLA/PHA mix for added strength but they required more flexibility during an impact which is why we chose Semiflex.

This specialized filament required alot of dialing in to achieve good results but once we had reduced the print speed and played around with the temperature, the finish was great. I am using an E3D V6 lite, which allows me to extend the PTFE sleeve to just below the hobbed direct drive. This is needed for printing such a flexible filament.

We have carried out extensive testing with the shock protectors and are now happy to offer them for sale. They are just £9.95 per pair plus postage and are available to purchase from ebay.

3DOM USA Glass Filled PLA Filament

3DOM USA have released details of their new filament. It’s glass filled PLA and promises to be tougher than standard PLA. 3DOM USA state that their latest filament prints as easily as normal PLA and does not require a heated bed.

The following information comes straight from the 3DOM USA website:

Glass Filled PLA 3D printer filament is a first-of-its-kind engineering-grade filament that can be used on any machine capable of printing standard PLA. Glass Filled PLA filament offers similar benefits of standard PLA such as a very low warp, low odor, and no special extruder or heated bed needed. But the power of its composite make-up allows it to be stronger, tougher and more flexible. In a comparison to parts 3D printed in standard PLA, Glass Filled PLA is:

  • 1.4 times stronger than PLA at 57 MPa of max tensile strength.
  • 1.3 times tougher than PLA with 34 J/m of Impact Toughness.
  • 1.9 times more flexible than PLA with a tensile elongation of 3.4% before failure.

Glass Filled PLA is an effort to advance engineered and practical-use 3D printed parts and components, but also to simply offer to users of PLA a product far improved.

Print Settings

Glass Filled PLA prints well at 190-210 C. These are general starting points for Glass Filled PLA, actual temperatures will vary from one printer to another. A heated bed is not necessary, though if you have one, set it to 40 C.

Filament Information

Quality: All 3Dom USA 3D printer filament is manufactured in our own production facility located in Fargo, North Dakota. We have complete control over the manufacturing process and are able to ensure consistent quality for every spool.

Diameter Tolerance: Variable diameter can cause big problems in your 3D printer. We use a multi-axis laser measurement system to control our filament diameter and ovality in real time during production. Every spool has the diameter and ovality measurements listed right on the box.
