Test of the 3D printer Sovol SV01, a very promising new brand!

This post is also available in: Français (French)

I will present you today a new 3D printer from Sovol 3D, which I received in early May as a beta tester before the product was released.

Sovol 3D is a brand new brand of 3D printer of Chinese origin, they now have only one printer reference, the Sovol SV01.

Main features of the SV01:
– Printing area 240x280x300mm
– Extruder in Direct Drive (titan type)
– Double Z-axis motor
– Ultrabase plate
– Resume printing in the event of a power failure
– Filament end detector
– 24v/350w power supply

There is no autoleveling system, but the installation of a BL Touch has been planned by the manufacturer and should not be complicated.

Concerning the price, this printer is sold for 349$ or about 305€, for the moment it is only available via the manufacturer’s warehouses in China, but the delivery is still quite fast, count between 7 and 10 days to receive it. It is possible on the other hand to have customs fees on the product, it remains rather random (I had to pay a 30aine of euro concerning me).

It is planned to be sold directly from European warehouses, and even on Amazon.

The price remains very reasonable for this type of printer, considering the options available: Direct drive, double Z axis, ultrabase, filament end detector…

Unboxing the printer

Delivered with a 250g spool and the usual accessories, the printer is already partially assembled, the entire electronic part is integrated in the lower part of the chassis, so there is no external control box.

At first sight the printer will be quick to install, there are only 2 parts to assemble and the control screen to fix. The instructions provided are quite detailed, in English.

The printer control screen, which looks very much like the Creality Ender 3.

The accessory box, with spool holder, filament end detector, power cable for European, and the classic spatula/clamp/allen keys…

Before going any further, let’s open the beast, curious to see the internal map. The wiring is clean with a 24V/350W power supply.

The motherboard is a Creality version 2.2, the same as the Creality CR-X, to see if an upgrade to dual extruder is possible on this machine, but it is already the 2nd Creality component after the screen, we can imagine that other components like engines are also provided by Creality.

I have received confirmation from Sovol that the manufacture of this machine is well subcontracted to date in Creality factories, so even if Sovol is a very young brand, it benefits from Creality’s experience in manufacturing their product.

Printer assembly

The assembly of the printer is really very simple and fast, 4 screws to put to assemble the 2 parts of the chassis together, everything is also already wired there will only be the screen to connect, the endstop of the Z axis and finally fix the coil holder at the top.

Sorry I forgot to take more pictures during the assembly, but it takes less than 15min to implement. Easier to assemble than an Ender 3.

Some remarks on the structure of this printer. Once assembled, the assembly is really stable, the ultrabase tray is glued directly to the tray but Sovol told me that an update was planned, the tray will no longer be glued, and replaced by a magnetic tray.

We also appreciate the reinforced profile in 2040 for the X axis, in order to better support the slightly heavier direct drive extruder.

Overall this machine seems to be really good quality, with good quality components.

First printing test

Before going any further and starting a first impression, it will be necessary to check several points:
– the parallelism of the X axis
– that the eccentrics of the print head are tightened securely
– that the eccentrics of the plate are also well tightened

It will also be necessary to adjust the level of the tray at the first start using a sheet of A4 paper and adjusting the height with the 4 wheels under the tray, I will not detail this procedure, we find lots of tutorials on Youtube on this subject : -) Just remember to do this operation when the tray is heated to 50-60°C, it is very important and not always specified.

It’s gone by the first impression!

It is always preferable to print the test model provided by the manufacturer on the SD card, this already makes it possible to check the correct operation of the machine, because if you encounter problems it could also be related to your settings in your cutting software!

The printing result is really clean, no particular problems for this first printing, no peeling, no under/over extrusion, really satisfying!

For the rest, I will use a profile under Simplify3D, starting from a profile created for the Creality CR10, I just change the size of the tray, and also modify the retraction distance to 2mm because we are in direct drive.

I start with a “test” impression that allows you to test different aspects of your profile. The result is pretty good for a first try, I’ll have some parameters to adjust, but it’s satisfactory for a first impression.

I continue in the series “test printing”, this time to test the behavior in bridge printing situation. She’s doing really well, I’m starting to like this machine!

I used for these 2 first impressions of the PLA+ Yellow of the Sunlu brand, at 210°C and 60°C for the tray, with very good adherence of the tray!

This time I’m launching a very big impression, about 35 hours of print, with PLA+ White Ivory Sunlu. The result is super clean!  Printing with a layer height of 0.15mm.

Another printing test, this time with emotion tech’s glitter green PLA filament, a flexrex, to test a little more the precision, very beautiful rendering, and perfectly functional joints.

Another Sunlu orange PETG+ test, printed at 230°/70°C, I wanted to see the grip of the PETG+ on this ultrabase tray, printed with a layer height of 0.20, and ventilation at 30%.

Great catchphrase! Once the printing was finished and the tray was still warm, it was almost impossible to remove the part by hand. Once the tray cooled down, the part came off on its own.

Finally a last little test for the road, Sovol offered me to try their PLA at the same time, sold in a pack of 2 white + black reels, available on Amazon but also on their site directly (with European warehouse so very fast delivery). The price on their site is really very correct, at 32$ on promotion to date, or 28€ for 2 or 14€ per delivery reel included! You can even get a welcome coupon of $5 for your first order, a very good deal, for a quality filament…

I let you already judge the perfect winding of their reel, which should greatly limit the risk of knots, you are not safe from improper handling of the reel either when you remove/remove it, always make sure to keep the filament tight!

And so here is a first test of the printing of this “pure” white. Printed at 200°C and 60°C for the tray and a layer height of 0.15mm. The result is just perfect, you don’t see the layers of impressions, it’s amazing!

Another small printing test, still at 200°, layer height in 0.20mm.

This white is really white as snow, so I took the opportunity to do a small test of lithophane, with a layer height of 0.20mm.

In conclusion, regarding this SV01, I was really surprised, knowing that it was the very first printer of this company and the first version of this machine. Really easy to assemble, it is a printer that I could recommend to a beginner without hesitation.

I really appreciate the direct drive, which should make it easier to print some filaments like flexible/tpu, it is quite rare to have this type of extruder for a machine in this price range.

If I had to compare it to an Ender 3/pro, in terms of functionality, it is clearly above it, certainly for a higher price, but it also offers a larger printing surface. The only negative point I see for this printer is that they could have equipped it with TMC2208/2209 drivers to make it quieter.
