The Prusa Pro HT90 is an industrial 3D printer (FFF\/FDM)<\/strong> with delta kinematics and a cylindrical print volume of \u00d8300 \u00d7 400 mm<\/strong> (28 L). It is designed for teams that want more predictable 3D printing of engineering plastics \u2013 from ABS\/ASA<\/strong> and PA<\/strong> to high-end polymers such as PEEK\/PEKK<\/strong> and PEI (Ultem)<\/strong> \u2013 without sacrificing speed, repeatability, and control over the working environment. Its two strengths are the actively heated work chamber up to 90\u00b0C<\/strong> and the interchangeable print heads<\/strong> (High-Flow up to 300\u00b0C and High-Temp up to 500\u00b0C) included in the package. <\/p>\n The HT90 is designed for “first-time” results with difficult materials and complex geometries. The practical advantages for professional work are: <\/p>\n Unlike classic Cartesian and CoreXY designs, delta kinematics<\/strong> move a lightweight head with three coordinated arms, while the detail remains stationary on the plate. This helps to achieve smoother surfaces and stable dynamics even with larger parts, especially when combined with Input Shaper<\/strong> (active vibration suppression). <\/p>\n Air control is also key: the HT90 uses a servo-controlled high-speed valve<\/strong> that redirects the air flow within milliseconds, plus a high-pressure turbine<\/strong> to cool the chamber after a cycle. This allows for cleaner overhangs with fewer supports, without the rest of the part being “overcooled.” Additionally, there is automatic control of the incoming air for materials such as PLA\/PETG, so that they can also be used with the chamber closed, depending on the profile. <\/p>\n The HT90 is designed for two typical operating modes:<\/p>\n According to the manufacturer, with the right settings and material, the HT90 can deposit up to 1 kg of PETG or ABS in ~8 hours<\/strong>, which is useful for quick iterations and short runs. Control is via a large 7\u2033 touch display<\/strong>, and automatic calibration relies on Loadcell<\/strong> for the first layer \u2013 the system measures the distance in the grid and calculates corrections without manual adjustments. <\/p>\n The software center is PrusaSlicer<\/strong> (professionally oriented, with ready-made profiles). For modeling and preparation, you can work with your preferred CAD\/3D software and import standard formats such as 3MF, STL, STEP, OBJ, and AMF<\/strong> into PrusaSlicer, then export the G-code for printing. <\/p>\n There are two main scenarios for networking:<\/p>\n The HT90 supports Ethernet (RJ45)<\/strong> and a detachable Wi-Fi module<\/strong>, as well as full offline use<\/strong> (including firmware updates via USB). This is a big plus for manufacturing and engineering organizations where data and access are strictly controlled. <\/p>\n The printer has a compact base<\/strong> relative to its volume and a vertically sliding door<\/strong> that saves space at the front \u2013 important when positioning it against a wall or in a laboratory row. The dimensions are 530 \u00d7 530 \u00d7 1050 mm<\/strong> (without the roll holder), and the height reaches 1470 mm when the door is open. The weight is 43.5 kg<\/strong> without packaging (50 kg with packaging), which is realistic for an industrial-grade system and requires planning for transport and installation. <\/p>\n Operating conditions:<\/strong> the device is intended for indoor use, at 20\u201332\u00b0C and up to 85% relative humidity (non-condensing). For the EU 230V version, the power supply is in the range 220\u2013240 VAC, 50\u201360 Hz (according to the documentation, depending on the version). <\/p>\n What’s included in the basic package:<\/strong> the printer itself, power cable, textured powder-coated printing sheet, Wi-Fi adapter, USB flash drive with sample files, Prusament ASA Jet Black 850 g, alcohol wipes, cutters, High-Flow head, High-Temp head, high-temperature nozzle replacement tool, PTFE lubricant, spare parts, roll holder, and brass nozzle brush.<\/p>\n The Prusa Pro HT90 (EU 230V) is an industrial delta 3D printer with a cylindrical volume of \u00d8300\u00d7400 mm (28 L) and active heating of the working chamber up to 90\u00b0C. It comes with two interchangeable heads (up to 300\u00b0C\/500\u00b0C), a plate up to 155\u00b0C, and a HEPA+carbon filter for a more controlled environment during 3D printing. <\/p>\n\n
