ColorFabb Standard Black 1.75mm PLA-PHA

Premium NGEN filament from Colorfabb. Hotend 230" Bed 65"

nGen is produced with Amphora ™ AM3300 polymer and uses specific colorFabb developed color concentrates for good opaque quality and highest possible brightness. Eastman Amphora ™ AM3300 3D polymer is a low-odor, styrene-free material uniquely suited for 3D printing enthusiasts, particularly those who need the flexibility to print within a wide processing temperature range.

Amphora AM3300 has good flow properties through the printer nozzle—even at lower temperatures than some other polymers require. These properties make AM3300 more workable at a wider breadth of temperatures, producing reliable results and resulting in less waste.

Amphora AM3300 can be made into high-quality filament that exhibits advanced overhang ability, excellent looks, and large printing temperature range—empowering a large panel of users to create durable and useful items.

To get the best possible quality out of any 3D printing material it is important to match the slicer settings with the material which is used. On this page we'll run through the most important settings and suggest good starting values ​​for various printers. If your machine is not in our list, use the general recommended settings.

In the table below you can quickly find values ​​for your machine, scroll a bit further down to read more about each setting.

Heated Platform

nGen is best printed on a heated build platform. You want to be near the heat resistance temperature of 85C. Therefore most 3D printers will do fine with 75C/85C platform temperature.

If your machine doesn't feature a heated platform, then you can look into using accessories such as BuildTak, 3Deeze and 3DLac. For small to medium sized parts the accessories can work, but for large parts covering the entire build platform it most likely will show warping on the bottom of the print.

Printing Temperature

The temperature we see when starting a print really depends on the chosen layer height and print speed.

Flow of material in mm3/s = (layerheight*nozzle width)*print speed

When considering normal settings such as 0.2mm layer height and 50 mm/s speed we recommend for most machines a processing temperature of 220C / 240C.

When settings are much different then a regular setup, for instance 0.05mm and 50 mm/s print speed the set temperature could be adjusted. In this case it's likely that you won't need as high a temperature as in Case 1, because the mm/3 s is 4x less.

Cooling

nGen is a highly efficient material, with elevated glass temperature of 85C but a processing temperature of 220C/240C meaning less heat to dissipate to cool down below glass temperature. It performs great on overhangs, as long as they are still attached to the main model.

If you're used to setting a 100% fan speed all the time, you might want to experiment with less cooling if you notice layer adhesion or part strength could be better. If a layer cools down too much it will adhere less to the next layer.

We also like the option of only activating layer cooling for the perimeter lines, the infill is not cooled and therefore should maintain the best possible layer adhesion.

Bridging

Most slicers will allow users to set special settings when a bridge is printed in a model. Usually we can see bridging speed, bridging cooling and sometimes also bridging perimeter width (or flow).

We recommend slower printing on bridges, since there's no material to support the printed line, we don't want to 'break the melt' by moving too fast. Slowing down the speed when bridging helps retain the melt strength and also allows the printed line to cool down in mid-air.

Cooling can be set at 100% to help the cool down of the first printed lines.

If you can still see the melt break when printing a bridge, try and increase the flow or bridge perimeter width.

Retraction

Before you start tweaking the retraction values ​​make sure you've found the sweet spot in terms of printing temperature and speed for your machine.

PLA retraction values ​​should be a good starting value for most machines. One can expect slightly higher values ​​of retraction speed and retraction length.

Coasting is a nice option included in Simplify. This is the act of stopping the extrusion just before a travel move is triggered, this helps get rid of the pressure in the hot-end and therefore also making a retraction move more effective.

We also like the option of only activating layer cooling for the perimeter lines, the infill is not cooled and therefore should maintain the best possible layer adhesion.

Minimal layer time

If you're familiar with the minimal layer time setting then you'll know this is what causes a printer to slow down when printing fine features on a model. Slowing down the print allows each layer to cool down a minimum amount of time. This is of course different for each material, because it depends on how fast a material can dissipate heat and how much heat needs to be dissipated.

For nGen we reckon you should be able to lower this value compared to your standard PLA value. How much exactly is hard to tell as it depends on the printer's cooling efficiency.
