Sovol SV07 Plus

About the Sovol SV07 Plus

Bambu Lab upended the whole consumer 3D printing industry when they introduced their 500mm/s X1 in 2022. Suddenly all other manufacturers realized their offerings were obsolete and when Bambu Lab introduced the lower cost P1S in 2023 they accelerated their plans for fast, highly automated printers.

Sovol introduced their response, the SV07, on May 13th, 2023. It follows the Creality Ender 3 clone concept that Sovol had been pursuing with models prior to the SV06 but incorporates some technologies Sovol developed with the SV06. It has been sped up to 500mm/s peak (250 mm/s typical) and is powered by Klipper firmware which uses a fast CPU rather than an underpowered microcontroller to perform rapid calculations. On August 29th, 2023, Sovol supersized the SV07 by introducing the larger SV07 Plus. It is identical to the SV07 except for a larger printing volume and higher capacity power supply.

Design

The SV07 Plus takes Sovol in a different direction than their earlier SV06 and SV06 Plus. It is a conventional Cartesian Creality Ender 3-style printer with a larger printing volume than the Ender 3: 300 X 300 X 350mm. It uses V-slot extrusions and POM wheels on all axes while the SV06 and SV06 Plus use linear bearings like the Prusa i3.

There are integrated belt tensioners, a parts drawer incorporated into empty space in the frame, and a magnetic, removable PEI-covered spring steel bed plate.

The key new feature with the SV07 Plus is the touchscreen, which is actually a full-featured Klipper host controlling the printer and enabling printing speeds of up to 500mm/s. It also allows full access via WiFi to any network-connected device.

The SV07 Plus uses a high quality, large capacity 600W Meanwell power supply. These power supplies are often used in commercial and industrial equipment and many users upgrade lower quality, generic power supplies in other printers to Meanwell power supplies. Such a large power supply means the SV07 Plus can devote a large amount of power to the bed heater: 420W. This helps such a large bed heat up quickly, 60°C in 90 seconds, which is about 30 seconds faster than most other printers.

Extruder

The SV07 Plus reuses the SV06 Plus extruder. This is an all-metal direct extruder with a high flow extended Volcano-style nozzle and a heating block mounted vertically to heat such a long nozzle. The entire metal extruder body forms a very large heatsink. A planetary gear system drives dual steel filament gears. This system increases torque, reduces weight and allows for a smaller, lighter extruder motor. A manual filament advancement and indicator wheel is in front while a gear release lever is on the right. All electrical components are plugged into a breakout board on the rear of the extruder with micro JST connectors. This makes replacing extruder electrical components much easier.

The extruder is surrounded by a new, large housing. It also holds a wraparound array of 18 very bright LEDs surrounding the nozzle.

All wires are bundled into a flat cable protected by fabric. Stiff support wires are bundled with the cable so that it holds its shape while still being flexible. It plugs into the breakout board and will stand up so that it will not sag, which might cause it to drag on the heatbed or snag a printed part.

Part Cooling Fans

High speed printers need strong part cooling and the SV07 Plus has had a huge upgrade over the previous SV06 and SV06 Plus. First there’s the standard 4010 (40mm diameter 10mm thick) blower fan with a wraparound duct blowing cooling air on the front and sides of the print. But this draws warm air from over the bed. This is the cooling fan arrangement on the Sovol SV06 and SV06 Plus and was reused so that the extruder did not need to be redesigned. It’s effective enough for a medium speed printer.

The big upgrade for the SV07 Plus is the inclusion of a 6020 axial fan directing cooling air from behind the extruder onto the rear of the part. It’s very large and is capable of outputting a lot of air.

This fan is so powerful it needs its own cable. It’s mounted to the right of the nozzle as seen from the front so that its airflow does not cool the nozzle.

Bed Leveling

The SV07 Plus uses the same 25-point non-contact inductive leveling system with the same sensor used on the SV06 and SV06 Plus. This system detects the steel of the bed plate, so non-metallic bed types will not work with this system. Unlike the SV06 and SV06 Plus, the SV07 Plus includes bed leveling knobs so that the user may manually correct the bed level. Although the printer automatically corrects the bed level, by adjusting the knobs to get as level a bed as possible, the printer will minimize corrections and the results will improve since this correction isn’t perfect.

Another new feature of the SV07 Plus is that the user can view the results of each tested leveling point on the screen.

Touchscreen

The 5” touchscreen is bright and responsive, but not what it appears to be at first glance. It is actually a full-featured KlipperScreen connected to a customized Klipper host - a MakerBase MKS KLIPAD50 V1.0 similar to a retail MakerBase MKS PI. It is like a Raspberry Pi that a user would install to run Klipper on another printer. It has onboard eMMC storage and a WiFi module. There’s also a port which runs KlipperScreen that plugs directly into a 5” touchscreen similar or identical to a MakerBase IPS50. The touchscreen is mounted on top of the board.

Since the display is a full KlipperScreen, it is quite extensive and has complete controls and menus. Advanced users can customize the menus and parameters displayed by altering the Klipper configuration.

The Klipper board connects to a wireless network and allows any network connected device to access the Fluidd web interface, which gives complete remote control of the printer. Mainsail is also enabled as an alternative. The

Brand Summary: Sovol

Sovol is a 3D printer brand known for producing innovative printers with more features than their competitors at a lower price. Their printers are beginner-friendly and have good build quality, but their entry-level printer, the SV01, lacks a bed leveling probe. While Sovol's community is still establishing itself, the company's support is well-regarded, and they have over 80,000 users. Sovol has experimented with complex dual extrusion features, which led to clogging problems and quality issues in some of their previous models. However, their current printers, such as the SV06 Plus, offer impressive features like 25-point auto bed leveling and a 500W bed heater. Sovol's varied printers appeal to different users, from new users to advanced users.
