Testing has been on-going for over two years now and we continue to have people test on new machines. So far, any machine we have had the material tested on has not had problems running the material, but must have a heated bed.
Our NYLON 12 Filament is a high strength, flexible, durable polymer. Other filaments sold in the “Nylon” category are co-polymers made from several materials and using additives for stability and as a binder. They work great and have their own unique qualities. Our material does not incorporate “other” materials. It is processed using only Nylon 12 and provides additional characteristics for 3D printed projects.
One of the foremost complaints when using other nylon filaments is the absorption of moisture. Whether in the original raw material before extrusion or after sitting in a finished product, moisture can cause end use problems while using it for printing. A comparison of materials has shown that PLA and Nylon 6/6 absorb up to 9.5% moisture at saturation levels. Nylon 12 has a saturation rate of 1.4%. Because of the long “hydrocarbon chain length” found in processed Nylon 12, it absorbs very little moisture.
One of the things we have seen with other printing materials is that when they are put under stress they will crack, separate, split, fail or whatever term you might use at the layer lines. Our material has shown that it fails randomly across the layers of filament showing that it has much better adhesion between layers. This produces a much stronger end product.
The crude but effective pull test….. with results showing cross layer failure
Typically our speeds are running @ 25-120mm/sec. Our experienced operators have far exceeded these speeds but push the limits of the printer head temperature. Since the software typically has a high end set point and the printer head is not designed for higher temperatures that would allow faster rates, we did our testing at 230°C – 265°C which all printers can handle. Our machines have been modified to handle much higher head temperatures and therefore get higher printing speeds. Newer 3D printers have a higher temperature capabilities built in to the software and mechanical hardware of the machine. We may in the future post these changes.
We have been using a very thin layer of Fubar Glue. 20-25 drops are all that’s necessary for a typical 8″ x 8″ bed. Spread evenly and dry thoroughly before using. Lasts for 10-25 prints before cleaning and re-coating the bed table.
Recently we started using a cheap mirror purchased at any arts and crafts store, then cut to size to match our printer bed. Works great and is really inexpensive. We clean it well with soap and water, then dry it completely. As a final cleaning before coating with glue we clean it with MEK or Alcohol to remove any oils and fingerprints. We coat with the glue and dry it until it turns clear. Then we attach it to the bed.
Currently yes, but if requested, we can provide White Nylon 12 Filament. This has an additive of color… Titanium Dioxide. It would however be a 6-8 week lead time as a special order. You would need to send us a special request. Use this Contact Form….
We are currently offering what most of our clients want and that is the 1.75mm diameter product. We have tested and produced 3mm product but so far we have not had much call for it. We have even been asked for 6mm product and have had small runs for one of our clients need.
