INTRODUCING: The Noztek Tolerance Puller

Taking the guesswork out of tolerance

Tolerance. If you’re experienced in 3D printing, you’ll know the stress that can come with printer jams and inconsistencies with print quality. These problems not only result in substandard and inconsistent quality of product, they interfere with your productivity; wasting precious time, money and material resources. Managing the filament tolerance resolves most of these issues. It is therefore of upmost importance that tolerance is monitored and controlled with any project. Enter the Noztek Tolerance Puller.

Designed from the ground up to tackle inaccurate and inconsistent tolerences, users are now able to determine the width of the filament, the speed at which it renders and the correction ratio. The system relies on tension to get smooth, reliable results, pulling the material from a larger nozzle on the extruder to a much smaller diameter in the puller ensures the tension is keeping the resulting tolerance consistent. We now also sell a water bath to cool the filament as it leaves the extruder and travels toward the Puller. The in-built error correction control will notice any discrepency and correct it accordingly throughout the process. This intelligent set-up will save you time and cost, while causing significantly less material wastage.

Our tests…

To understand the workings of this machine, below are the results of one of our in-house tests. You’ll be able to generate these graphs from your own tests and activity using our bespoke software downloadable from the Noztek website.

Figure 1

In figure 1, we see that we started with semi-auto mode at 25 RPM then switched to auto-mode which adjusted the speed to around 22 RPM. The auto-mode now adjusts every 30 seconds (we can see it decreasing until reaching the correct speed).

Figure 2
Figure 3

Figures 2 and 3 display a test with auto-mode only. 

On both tests we can see that we had a tolerance of strictly +-0.1 but most of the time we have a tolerance of about +-0.05.

 

A higher speed will give a more consistent measured speed. (target speed in Light Blue and measured speed in Dark Blue).

As with all of our Noztek products, the Tolerance Puller is best used alongside other Noztek equipment. Results will be highly dependent on the quality of the extrusion (flow, roundness etc). Therefore using this machine alongside a Noztek extruder and Noztek Filament Winder will give best results. We recommend also using a dehydreator to remove any residual moisture from the resin before extruding. This leaves less room for error when it comes to monitoring your tests, it also significantly further reduces waste. Check out our model here. The benefits of having the entire Noztek set up really are unbeatable in terms of cost, time and material efficiency.

At Noztek, we’re constantly improving our innovations. We stay up to date with the current market and believe we have the best equipment for all extruding requirements.
