MakerGeeks Description

Current usage for 3D Printing:

The following come from the efforts of just a few Printer Operators.  As noted, in the 645 Samples page, taulman is working to dramatically enhance the available usage and processes information to the end user.
  • NOTE: Current 645 measures 1.76mm to 1.83mm dia in a slightly oval shape due to the draw and cooling process.  The line cross-section is constant, however users should make a slight adjustment to their "Material Dia" (1.78mm - 1.80mm) settings to accommodate this slight variance.
  • Layer Height = Any
  • Speed - 645 has a slightly higher viscosity than other printing materials.  As the layer height exceeds 50% of the nozzle dia, printing speed should be adjusted downward ~10% - 20%
  • Retraction - again, due to a slightly higher viscosity, the retraction distance may need to be lengthened.
  • Excessive bubbles in the printed thread are an indication of a higher than required print temperature.
  • Reducing Print temperature below 238 will result in less thread opacity due to recombination with the atmosphere, however this will also reduce bonding in layers exceeding 25% of nozzle dia.
  • Shrinkage is equal to ABS and can be controlled using garolite (LE) as a print table cover/plate
  • Heated beds help just as they do for printing with ABS
  • Printing a larger amount of material for the first layer of a print on garolite will make the printed part extremely difficult to remove.
  • While printing with a higher infill percentage will make a stronger part, it is probably not required.  When we exceed 50% fill, it no longer provides any noticeable benefits other than optical.
645 Nylon Co-Polymer consists of the purest form of a delta transition of Nylon 6/9, Nylon 6 and Nylon 6T with a crystallinity optimization process in addition to post processing for maximum bonding during a thermal transition (3D Printing).

Construction = From granule form through nylon extruding systems to a 12 station extrusion to draw, 4 chiller loops with 2 post processing stations to a final draw of 3mm or 1.75mm round line.
  • Processing base purity = maximum available with current base chemistry.
  • Processing additives = none
  • Color additives = none
  • UV inhibitor additives = none – reduced susceptibility based on optical clarity/reflection.
  • Flame Retardant additives = none
  • Expected Tensile Strength, Yield = 16,533 psi
  • Expected Elongation at Break =120 %
  • Melt temperature = 194C
  • Print Temperature = 230C – 265C
  • Pyrolysis Temperature = 330C
  • Color = none
  • Crystallinity optimization = maximum allowable to a 50% tear/ 50% break (when printed)
  • Expected Optical Properties = true reflective, true absorption, optically correct for cylindrical thread/line.
  • Expected Opacity = <5% - currently unmeasured

Safety                                 645 meets the EU's "REACH" requirements as defined by the ECHA European Chemicals                                                     Agency.  There are NO additives or chemicals in 645 that are listed in the REACH Directive.

645 Contains NO toxic chemicals.  
As with all 3D Printing using heated polymers, Caution should be used so as NOT to come into
 contact with the molten 645 (194C+) as it will adhere to ALL cellulose surfaces, including skin.

         Again, just hit "Print"!

News from the Maker Desk
Happy Monday to you... hope you are doing great today; wanted to share something that was on my heart this morning about MakerGeeks and what’s going on and what the next steps are for us.

Almost 3 years ago we started selling 3D Printer filament(all of it from China) and over the next 2 years saw a booming business come out of those items; reselling filaments from China, Germany and the Netherlands. About a year and a half ago we started with a single extruder and a dream to start making 3D printer filament in bulk scale here on US soil… back then I thought that 1 extruder and me working part time would make more filament than I could sell in a life-time. Well, within just a few months we had bought another extrusion line and hired our first full time operator just to keep up with demand.

Now, surly we would have enough filament to last a life-time; NOPE… in just a few more months we added another extrusion line and lots and lots of overtime and weekends. Now we…
