Specifications

Smart features

The 3D printer is characterized by a portal-type three-axis design employing mortar layer-by-layer extrusion technology, and its print volume represents a cube with a side of 120 centimeters. With a standard layer thickness of 35 millimeters, the device features repeatability of one millimeter and the Z-axis accuracy of five tenths of a millimeter.

The MiniPrinter PRO comes with a pumping system, giving customers a choice of three options depending on their printing needs and volumes.

Rendering files for printing is carried out using in-house developed slicing software that supports STL and DXF formats.

The standard package includes the installation, one of three types of pumps, proprietary slicing software with a library of three-dimensional objects, and one ton of dry mortar mix.

The machine is compatible with third-party mixtures, with all the necessary requirements for consumables set-out in the instruction manual.

Bottom line

Combining excellent precision and repeatability with a high degree of automation, the Constructions-3D MiniPrinter PRO is a cutting-edge machine that can dramatically transform modern construction. Indeed, the printer impresses with the high-end technologies used in its components, huge build volume, and undeniably quality hardware. The product is designed to yield consistent results with minimum effort engaged.

In addition to the MiniPrinter PRO, the Constructions-3D’s lineup of equipment also includes a version for educational institutions, the ultra-large MaxiPrinter, and a device for evaluating the properties of ready-to-print mortar mixes.

FAQ

What is the difference between the three pumping systems?

The Access pack comes with a wet hopper pump requiring pre-mixing of materials, and suits for low-volume printing. The more advanced Research pack includes a double mixing pumping system that automatically mixes mortars. This option is ideal for intensive use. In the most capable Production pack, the double mixing pump is supplemented with a silo for automated material feeding, which is extremely useful for continuous industrial production.

What materials can the MiniPrinter PRO process?

The MiniPrinter PRO prints with mortars, plasters, and glues. The manufacturer offers proprietary mortars, but the printer is also compatible with any other materials meeting the pumping system requirements, including fiber-filled mixes with up to 2% fiber content.

Can I use different nozzles with the MiniPrinter PRO?

Yes, the MiniPrinter PRO features a removable extruder with interchangeable nozzles with a diameter of 10–30 mm.
