What should my extrusion width be?
There is no general rule of thumb for the best extrusion width. However, it has been found that the extrusion width should be between 100 and 140 % of the nozzle diameter. Some experts also advise a slightly higher extrusion width, which depends on the size and type of printed object.
What is the thinnest you can 3D print?
Too thin walls When scaling down a model, it could happen that walls become too thin to be printed. Most 3D printers have a set nozzle size with a diameter of 0.4mm or 0.5mm. Although this works for most models, problems could arise when layers smaller than this nozzle size need to be printed.
How fine can a 0.4 mm nozzle print?
This means you can print exceptional detail, and it won’t take forever. That’s because you can print down to layer heights of just 0.1mm, or up to 0.3mm using a 0.4mm 3D print nozzle.
What is extrusion factor?
The extrusion multiplier, which is called “flow rate” in Ultimaker’s Cura, specifies the rate at which your printer will extrude material. Most materials use a flow rate between 90% and 110%, but you can increase this value above or below these percentages.
Can a nozzle be larger than the extrusion width?
Each extruder can have its own unique extrusion width, so make sure you select the appropriate extruder from the list of the left to view the settings for that specific extruder. If you extrusion width is significantly smaller than your nozzle diameter, this may cause extrusion issues.
How many lb / hr does a 90 mm extruder produce?
(90-mm) extruder with 24:1 L/D was expected to produce between 500 and 550 lb/hr of HDPE if it had been fitted with a 125-hp motor and geared for a maximum of 125 rpm. A 2.5-in. (65-mm), 24:1 extruder was expected to obtain 200 to 225 lb/hr of HDPE with a 60-hp motor and geared for a maximum of 125 rpm.
How big of an extruder do I Need?
Processors tend to recommend a much larger extruder than what’s really necessary for the job and the capabilities of the downstream equipment. Here’s a rough estimate of single-screw extruder outputs at 100 rpm based on a specific gravity of 1.0 (polystyrene).
What’s the maximum speed of an extruder screw?
The screw speed was 36 rpm with a maximum of 125 rpm. Sitting nearby was an older 4.5-in, 30:1 extruder with 200 hp that would have done fine. But the processor preferred the new line because it was easier to operate.
