Four Heads Are Better than One with Stacker S4 3D Printer – ENGINEERING.com

by • May 4, 2016 • 8s Comments

It hasn’t occurred as rapidly as the hobby printing device explosion that began in 2012, but a new wave of 3D printing devices is slowly starting to emerge that implements industrial-grade advancement at pretty additional low-cost prices than are on the market now. Manufacturers such as Roboze and 3ntr have released machines capable of handling industrial-grade materials without having to rely on companies like Stratasys. On April 25-29 at Hannover Messe, the world’s major trade fair for industrial advancement, another new 3D printing device offered manufacturing-level 3D printing with quad-extrusion capabilities.
The Stacker S4 is the evolution of the original Stacker 3D printing device, launched on Kickstarter in February 2015 by startup Stacker, LLC. The original Stacker brought a few informative showcases to the world of futilized deposition modeling (FDM) 3D printing. For instance, the use of four separate extruders allows for the Stacker to 3D print four copies of the same object in four various materials and colors. Single-object printing can in addition be performed with one extruder, and multi-material or multi-color printing on a single object can be utilized with the four print heads. The original Stacker in addition featured an expandable Z-axis, enabling for a create envelope that ranged of 250 mm x 450 mm x 220 mm to 250 mm x 450 mm x 600 mm (9.8 in x 17.7 in x 8.7 in to 9.8 in x 17.7 in x 23.6 in), but that captalent appears to be missing of the latest option of the Stacker.

(Image courtesy of Stacker.) The most noticeable upgrade that the Stacker S4 brings to the table is dimensions. With the creation of the Stacker S4, the Stacker team appears to have foregone the expandable Z-axis of the original and just given the new machine an astounding create volume of 355 mm x 525 mm x 655 mm (14 in x 20.7 in x 25.8 in). To carry this dimensionsable gantry around, the S4 has a mobile cart, building it suitable for transport in lab or school environments. In addition included is a universal filament mount that supports the four material spools necessary for quad printing. But, most of the original showcases of the Stacker S4 stay, such as a heated aluminum bed, layer thicknesses as satisfactory as 100 microns, and an SD card reader.

The machine in addition uses Stacker’s “hybrid” hot end, that allows for users to swap nozzles when via materials with higher melting temperatures, such as nylon and co-polyesters. This, along with the talent of the printing device’s four extruders to reach up to 300°C, opens the S4 up to 3D printing a wide variety of materials. In particular, the machine is being marketed for use with colorFabb’s wide range of filaments.Other than the talent to 3D print four objects at the same time, the Stacker platform does not bring a massive amount of advancement to futilized deposition modeling advancement. If the printing device may use these four print heads to fabricate four various objects or four various portions of the same object, much like to Autodesk’s Project Escher, its future for industrial use may be much greater. But, for making batches of objects, particularly with colorFabb filaments, the Stacker S4 may come in handy. Either way, the platform’s existence indicates that there may be a demand for industrial-grade machines. If so, there can surely be a new wave of additional low-cost, pro 3D printing devices that may one day enable a shift to local 3D printing of end parts.
