Raise3D Pro3 Plus HS: when extra build height matters
The Raise3D Pro3 Plus HS shares a dual print head, the same material list and the same bed area with the Pro3 HS. It adds build height with a taller, heavier frame. This guide uses the Raise3D user manual and product page to explain which parts benefit from that height and what the machine needs from your workspace.

The short answer
According to the Raise3D manual, the Pro3 Plus HS prints 300 × 300 × 605 mm with one extruder and 255 × 300 × 605 mm with both, versus 300 mm of build height on the Pro3 HS. This vertical space may avoid splitting a tall part, after checking its orientation and any added features in ideaMaker. The machine stands 1105 mm tall and weighs 64 kg net, versus 760 mm and 54 kg. Both models list the same 300 mm/s standard speed.
What the Plus actually changes compared to the Pro3 HS
The specification table in the Raise3D manual lists both models side by side. The Pro3 HS prints 300 × 300 × 300 mm with one extruder and 255 × 300 × 300 mm with two. The Pro3 Plus HS keeps exactly the same bed area but rises to 605 mm: 300 × 300 × 605 mm single-extruder and 255 × 300 × 605 mm dual-extruder. Width drops by 45 mm as soon as the second head is active, on both machines.
The same table lists these shared specifications: dual head with electronic lifting system, 1.75 mm filament, 300 mm/s standard printing speed, flexible steel plate with BuildTak, mesh leveling with flatness detection, heated bed up to 120°C and nozzle up to 320°C. Available nozzles run from 0.2 to 1.0 mm, with 0.4 mm fitted by default.
The table therefore does not list a higher standard speed for the Plus. Choose the build volume around your part dimensions, then compare the required space and handling. If you are also considering the Raise3D Pro3 Plus without the HS suffix, keep the generations and their specifications separate. No comparative precision or throughput measurement was performed here.
The parts that justify 605 mm of height
The first case is straightforward: a part whose smallest stable orientation exceeds 300 mm in height. On a Pro3 HS, it cannot print in one piece. You split it in the slicer, print two or three segments, then join them. The Plus prints it in a single run, provided you leave room for any brim, raft, or purge tower you enable in ideaMaker around the model.
The second case covers long parts you could lay flat but would rather print upright for surface or support reasons. A part lying across 300 mm fills the whole bed and, depending on its geometry, may need supports on a visible face. Printed vertically, it frees bed area for other parts in the same batch. Raise3D positions the series for small-batch production of end-use parts and tooling fixtures.
The third case is the stacked batch: several tall parts printed together. The product page names end-use parts and tooling fixtures as the intended uses. If your output is mostly short parts, the extra height sits empty most of the time. In that situation a large-format 3D printer with a wider bed answers the need better than a taller one.
Dual extrusion: usable width shrinks, height stays
The manual shows width falling from 300 to 255 mm when both extruders are in use, on the Pro3 HS and the Plus alike. The 605 mm height is unchanged. For a tall part printed with soluble or dedicated support material, that matters: you keep the full vertical gain, but the part must fit within 255 mm of width.
The material list in the manual includes dedicated supports, PET Support and PPA Support in the Industrial range, plus PVA+ in the Premium range, alongside the PPA CF, PPA GF, PET CF, and PET GF composites. The manual does not, however, provide any matrix stating which support prints with which composite. Before buying for a tall composite part with dedicated support, require a named ideaMaker profile for the exact material/support pair, or written confirmation from Raise3D: that validated pair is what makes a dual extruder and extra height work together.
Mind the real dimensions, though. The manual gives the maximum volume per extrusion mode without detailing what a brim, raft, or purge tower consumes on the bed. Check your model in ideaMaker with the dual-extrusion profile active and the options you will actually use before concluding that it fits.
What the taller machine demands of your shop
The manual lists machine size as 620 × 626 × 760 mm for the Pro3 HS and 620 × 626 × 1105 mm for the Plus. The footprint is identical, but the Plus adds 345 mm of height. On top of that, Raise3D asks for installation clearances for operation and maintenance: 50 cm on the sides, 80 cm at the front, 20 cm at the back, and 60 cm above. A low shelf or sloped ceiling can rule out the Plus where the Pro3 HS fits.
On weight, the table lists 64 kg net for the Plus versus 54 kg for the Pro3 HS, and 88.7 kg gross on a pallet versus 75.7 kg. The manual says not to lift the machine on your own. It lists four swiveling, double-locking casters among the main parts, but does not describe moving the printer up stairs or over a threshold: settle that point before delivery.
Ambient conditions are shared: 15 to 30°C and 10 to 90% relative humidity, non-condensing. The power supply accepts 100 to 240 VAC, rated at 3.3 A at 230 V for a 600 W unit. The manual also states this is a Class A device that may cause radio interference in a domestic environment, and that it emits a thermoplastic smell during operation; the specification table separately lists a HEPA filter with activated charcoal.
Materials, software, and features common to both models
The manual lists Raise3D materials in four families: Hyper Core (PPA CF, PPA GF, ABS CF), Hyper Speed (PLA, ABS), Industrial (PPA CF, PPA GF, PET CF, PET GF, PETG ESD, PET Support, PPA Support), and Premium (PLA, ABS, ASA, PETG, PC, TPU-95A, PVA+). Third-party filaments go through the Open Filament Program, with profiles Raise3D publishes for ideaMaker. Raise3D recommends its own filaments and default settings and warns users to be careful with unverified materials.
ideaMaker is the listed slicer, on Windows, macOS, and Linux. It accepts STL, OBJ, 3MF, OLTP, STEP, STP, IGES, and IGS files, which spares a conversion step from CAD for STEP and IGES. The printer runs from a 7-inch touchscreen over Wi-Fi, Ethernet, or USB, with a live camera, power loss recovery, and a filament run-out sensor.
Two features deserve a check. The product page advertises automatic filament switching and an RFID sensor, but the manual's specification table marks both as available, coming soon. Ask your reseller about the status of these functions on the shipped firmware before making them a purchase criterion.
Deciding between the Pro3 HS and the Pro3 Plus HS
List your actual parts with their dimensions in the orientation you would print them. If none exceeds 300 mm in height, the Pro3 HS gives you the same bed, materials, and software in a shorter, lighter chassis. If several parts cross that line, or you spend time bonding segments, the Plus removes that step.
Then check the location: available height with 60 cm of clearance above, 80 cm in front, and access that lets two people set down 64 kg. Budget time for setup too: the manual describes a five-step offset calibration of about one hour in the start-up wizard, after unpacking and removing the 24 security spacers.
Finally, account for total cost rather than the machine alone: filament, the external 2.5 kg storage boxes sold separately, optional nozzles, and the RaiseShield warranty extension that must be bought with the printer. The startup budget tool helps you lay out those items before requesting a quote, since Raise3D directs buyers outside the US to its reseller network.
