About micro 3D filament line
Preliminary information, subject to improved changes
The 3D filament line consists of a stainless steel water bath to cool down or to control the temperature (no voids) of the 3D print filament. Note: Polymer compositions that are difficult to dry will skip the water bath section. The filament dryer at the end of the water bath guarantees a dry filament which is necessary to be accurately checked in the laser measurement unit, where the filament diameter is monitored constantly. Further downstream the custom 3D print filament enters the transport godet where you can control the draw rate, which enables you to be flexible in your processing workflow. The inline draw speed can be controlled and monitored on the control box which is part of the total set up.
Finally, the 3D print filament needs to be wound onto a standardised industrial bobbin. The torque of this filament winding unit can be controlled to achieve tight winding of the filament.
The 3D print filament line is able to provide the basis to process the typical FDM polymers into an accurate filament, well within the industry norm of ø1,75 mm +/- 0,05 mm 3D print filament with unique (custom design polymer matrix) properties. When combined with our MC 15 HT or MC 40 compounder the 3D filament line should be equipped with an optional pre-feeding unit.
The water bath has enough cooling capacity, it is equipped with an inlet and outlet connector, where a chiller or thermostat can be attached. The filament is dried with compressed air which can be connected at the bottom of the filament dryer.
As a last line of defence, the laser unit checks the diameter of the 3D filament and provides data to the Filament Drawing Godet. This becomes handy when the diameter of the filament, tends to travel to the limits of its internationally accepted tolerance. The Take-up Winder unit will properly wind the newborn 3D filament onto a standardised industrial bobbin for a possible subsequent analysing step or to be fed into a granulator for recycling steps or further compounding purposes.
The 3D FL can produce accurate filaments of FDM typical Polymer matrixes from a minimum of 500 grams of material with a wide range of line speeds, ensuring the generation of fast R&D sample material for subsequent testing or production purposes. If you do not need to produce a bobbin, such as when feeding the 3D filament directly into a 3D printer, the winding section can be omitted.
The 3D FL can be easily added to our latest MC 15 HT and MC 40 micro compounders. The 3D FL is also backwards compatible with earlier (legacy) models of MC 15 compounders, designed by Xplore.
