Dual Gear Direct Drive Extruder

Creality Ender 3 S1 Review - Dual Gear Direct Drive Extruder - 3D Printerly

Nicknamed, the “Sprite” extruder, this direct drive, dual gear extruder is very light compared to most other models, giving users less vibrations and jerky movements, along with more precise positioning. It supports a wide range of filaments including PLA, ABS, PETG, TPU & more.

Loading filament into this extruder is so much easier than with a Bowden extruder, and it feels very sturdy & well-made. Once your hotend is heated up, you can easily load filament through the extruder by hand, and even use the control screen to move the extruder to extrude filament.

It has two chrome steel gears engaged at a 1:3:5 gear ratio, along with a pushing force of up to 80N. This produces smooth feeding and extrusion without slipping, even with flexible filaments like TPU.

The main upside to this extruder is the lightweight design, weighing only 210g (ordinary extruders weigh about 300g).

CR-Touch Automatic Bed Leveling

Creality Ender 3 S1 Review - CR-Touch Automatic Bed Leveling - 3D Printerly

One of the main features that users will love with the Ender 3 S1 is the automatic bed leveling feature, brought to you by the CR-Touch. This is a 16-point automatic bed leveling technology that takes a lot of the manual work out of operating this 3D printer.

Rather than use the paper method and manually move the extruder to each corner, the CR-Touch will automatically calculate the bed level and calibrate the measurements for you. It basically modifies the G-Code to account for an uneven or warped bed.

It will only require you to manually input the center calibration to ensure it’s working properly, though that is also assisted.

High Precision Dual Z-Axis

Creality Ender 3 S1 Review - Dual Z-Axis Leadscrews - 3D Printerly

A feature that has been missing from the Ender series is the dual Z-axis, so finally seeing this high precision dual Z-axis on the Ender 3 S1 is very exciting to see. From the quality I have been seeing on this machine, and comparing it to my Ender 3, I can definitely see a difference.

Sometimes you’d get layer skips and other imperfections, but that is practically eliminated with the features brought to you by this machine.

This combination of the Z-axis dual screw along with the Z-axis dual motor design brings you a much smoother and more synchronized movement, resulting in a much higher instance of clean 3D prints, without those uneven layer lines and ridges on the side of your print.

I’m sure it’s one of the biggest factors to improving the print quality.

32-Bit Silent Mainboard

3D printing used to be a very loud activity, but manufacturers have solved that problem by bringing in the 32-bit silent mainboard. It significantly reduces the noise levels, which I can definitely appreciate, having the original Ender 3.

The motor sounds aren’t heard at all. You do still get the fairly loud fans active (under 50 dB), but they aren’t too bad and you can still do your usual activities without being disturbed much depending on your personal tolerance and distance from the machine.

Quick 6-Step Assembling – 96% Pre-Installed

We all love a quickly assembled 3D printer. The Ender 3 S1 (Amazon) has made sure to make assembly much easier, stating a 96% pre-installed machine with a quick 6-step assembly process.

I’d recommend watching the video below before you assemble your machine so you can make sure you get it right. I managed to put my vertical frame on backwards which confused me, before noticing my mistake and correcting it!

Assembly for me was really easy, having much appreciation for having things like the extruder, tensioners, bed, and even the dual Z-axis pretty much done for me. This design also makes maintenance of your 3D printer simpler and easier in the future.

You also have an instruction manual that gives you the simple steps to assemble your printer.

PC Magnetic Spring Steel Sheet (Flexible)

Creality Ender 3 S1 Review - PC Spring Steel Print Sheet - 3D Printerly

The PC spring steel sheet is a lovely addition that gives users the ability to “flex” the build plate and have 3D prints pop off nicely. The adhesion is really good as well, with models sticking nicely without any extra adhesive product.

It’s basically a combination of a PC coating at the top, a spring steel sheet in the middle, with a magnetic sticker at the bottom attached to the bed.

You no longer need to dig away at the build plate like a caveman as we all did previously, just a simple removal of the magnetic printing platform, bend it, and the print comes off smoothly.

There are so many features on this machine that makes our 3D printing lives so much easier, so we can focus on finding new awesome things to 3D print!

Do watch out for PETG since that can stick a little too well. You can apply a 0.1-0.2mm Z-offset in your slicer specifically for PETG prints.

4.3-Inch LCD Screen

Creality Ender 3 S1 Review - 4.3-Inch LCD Screen - 3D Printerly

The 4.3-inch LCD screen is a pretty nice touch, especially with the way it is assembled. Rather than require you to put screws into the back panel, it has a nice “slip-in” design where a metal pin fits inside the screen and slides in smoothly, then clips into place.

The actual operation of the touchscreen and the user interface has a mixture of a traditional and modern design. Everything that you need is easy to find, having the standard “Print”, “Control”, “Prepare” & “Level” options.

It shows you the temperatures of the nozzle and bed, along with the fan speed, Z-offset, flow rate, print speed percentage, and X, Y, Z co-ordinates. The lights automatically dim after 5 minutes of inactivity, saving some energy.

The only issue is, it doesn’t allow you to turn off the beeping sounds for each click which is slightly loud.

Filament Runout Sensor

Creality Ender 3 S1 Review - Filament Runout Sensor - 3D Printerly

If you’ve never run out of filament without having a filament runout sensor, then you might not appreciate this as much as some users out there. Having this feature is a big deal that all 3D printers should have.

When a 15-hour print is on the 13th hour going strong and your filament starts running out, the filament runout sensor can be a lifesaver. It is a small device placed before your extruder so that when filament stops passing through it, your 3D printer will pause and prompt you to change the filament.

After you change the filament over and select continue, it will go to the last location and continue printing as normal rather than continue printing with no filament. It’s a great feature, but do beware, you may get a layer line depending on how well the layer adheres to the previous layer.

Power Loss Print Recovery

Creality Ender 3 S1 Review - Power Loss Recovery - 3D Printerly

I actually have a power loss print recovery save one of my 3D prints, since the plug had come out accidentally. I switched it back on and was prompted to continue my print, selected continue, and it started printing like nothing had happened.

This is another lifesaver feature that users will appreciate. Whether you have a blackout, or an accidental plug removal, you can save those really long prints and not have to worry about these issues.

XY Knob Belt Tensioners

Creality Ender 3 S1 Review - XY Belt Tensioner - 3D Printerly

The XY knob belt tensioners are a neat feature that makes operation easier. You used to have to undo the screws that held the belt in place, apply some pressure to the belt at a weird angle, and try tighten the screw at the same time, which was quite annoying to do.

Now, we can simply twist the knob on the X & Y axis to tighten or loosen the belts to our liking. This enables you to make sure you are getting the best quality with the optimal belt tension.

International Certification & Quality Assurance

Creality made sure to connect some quality assurances and international certification to the Ender 3 S1. It has passed certification from various professional testing organizations, having safety certificates like the CE, FCC, UKCA, PSE, RCM & more.

When you receive your Ender 3 S1 (Amazon), you’ll definitely notice the high level of craftsmanship and design that went into it.

Benefits of the Ender 3 S1

  • Print quality is fantastic for FDM printing from the first print without tuning, with a 0.05mm maximum resolution.
  • Assembly is very quick compared to most 3D printers, only requiring 6 steps
  • Leveling is automatic which makes operation a lot easier to handle
  • Has compatibility with many filaments including flexibles due to the direct drive extruder
  • Belt tensioning is made easier with the tensioner knobs for the X & Y axis
  • The integrated toolbox clears up space by allowing you to keep your tools within the 3D printer
  • Dual Z-axis with the connected belt increases stability for better print quality
  • Cable management is really clean and not in the way like some other 3D printers
  • I love the use of the larger SD card rather than the MicroSD since it’s nice to use and harder to lose
  • The rubber feet at the bottom help reduce vibrations and improve print quality
  • Has the tough yellow bed springs that are firmer so the bed stays level for longer
  • When the hotend reaches below 50°C it automatically turns off the hotend fan

Downsides of the Ender 3 S1

  • Doesn’t have a touchscreen display, but it’s still really easy to operate
  • The fan duct blocks the front view of the printing process, so you’ll have to look at the nozzle from the sides.
  • The cable at the back of the bed has a long rubber guard which gives it less space for bed clearance
  • Doesn’t let you mute the beeping sound for the display screen
  • When you select a print it starts off heating just the bed, but not both the bed and the nozzle. It does heat both at the same time when you select “Preheat PLA”.
  • No option I could see to change the color of the CR-Touch sensor from the pink/purple color

Unboxing & Assembly of the Ender 3 S1

Here’s the initial package of the Ender 3 S1 (Amazon), a decent sized box that weighs around 10KG.

The display screen contains these metal pins that fit inside the display screen bracket, making assembly slightly easier.

Creality Ender 3 S1 Review - Display Screen Pin Connection - 3D Printerly

The assembly process should take you around 10 minutes or even less if you have experience putting 3D printers together.

Step 1: Attach the nozzle assembly to the mounting back panel with four M3 x 6 hexagon socket head cap screws.

Step 2: Clip the wire clamp to the back panel of the X-axis motor

Step 3: Place the main frame on the base and attach two M5 x 45 hexagon socket head screws on each side

Step 4: Place the display bracket on the side of the right profile, then tighten with three M4 x 18 hexagon flat round head screws

Step 5: Align the pins on the back of the display with the large holes on the display bracket and slide them down to clip it in place

Step 6: Attach the spool holder pipe to the right end of the material rack, then attach it onto the front slot of the profile. Press down to clamp into place

This is the main assembly complete, then you want to attach the relevant wires and ensure the voltage level is set correctly based on your local voltage (115V or 230V). After this is complete, we can plug in the power cable and get to leveling the printer.

Here’s a front view of the assembled Ender 3 S1.

Leveling of the Ender 3 S1

The leveling process is fairly simple. You want to ensure the four knobs are screwed in a decent amount so they aren’t loose, then you simply select “Level” from the main display screen.

This will get straight into the automatic 16-point leveling process where the CR-Touch will operate across the bed to measure and compensate the bed distances.

Creality Ender 3 S1 Review - Bed Leveling Process - 3D Printerly

Here is the automatic leveling in action.

Creality Ender 3 S1 Review - Bed Leveling Process 1 - 3D Printerly

It measures 16 points in a 4 x 4 fashion, starting from the bottom right.

It then finishes a measurement in the middle and prompts you to manually level the middle to enable an accurate Z-offset. This can easily be changed afterwards through the control screen.

Creality Ender 3 S1 Review - Bed Leveling Process 5 - 3D Printerly

If you didn’t get a prompt for the Z-offset, it’s advised to manually configure your Z-offset by homing your printer, then moving your Z axis to 0. This is telling your printer, the nozzle should be touching the bed, but it may not be.

You then want to take a piece of A4 paper, and do the manual leveling method just for the middle of the bed, but moving the Z-axis through the control knob with the Z-offset. Once you can slightly wiggle the paper, the Z-axis has been properly configured and leveled.

Check out the video below by Pergear showing this process.

Print Results – Ender 3 S1

Alright, now let’s finally get into the actual 3D prints that the Ender 3 S1 (Amazon) produced! Here is an initial collection of the 3D prints, then I’ll show some closeups further down.

Creality Ender 3 S1 Review - Collection of 3D Prints - 3D Printerly

Here are two test bunnies, the left made from white PLA and the right made from black TPU. It’s surprising how you can successfully 3D print TPU even at a 50mm/s speed. These came on the USB.

Creality Ender 3 S1 Review - Bunny Test Print White PLA & Black TPU - 3D Printerly

We have a nice Two-Way Screw combination of a screw and nut, but we did have an issue with the nut towards the end of it.

The nut managed to lose adhesion, possibly due to the filament underneath not being totally clean along with the movement back and forth, but all the other 3D prints adhered perfectly.

Creality Ender 3 S1 Review - Screw & Nut 1 - 3D Printerly

Luckily, it still works as intended. I had to spin it up and down quite a few times to get the material smoother, as well as adding some PTFE oil.

Creality Ender 3 S1 Review - Two Way Screw Black PLA - 3D Printerly

This is a cool little Jewelry Box made from black PLA. The layers are very clean and I don’t see any imperfections really, other than some light stringing that can be easily rubbed off. I couldn’t find the file but here’s a similar Threaded Container.

This Ender 3 handle made from black PLA came out really nicely, you can see everything is in order. This file came on the USB.

Creality Ender 3 S1 Review - Ender 3 Handle Black PLA - 3D Printerly

To test some tolerances, I printed this Flexi Rex out of black PLA. It did require some force to get the joints moving, but this is due to the steps per mm being a little more than needed. The Ender 3 S1 had a steps per mm of 424.9, but lowering it to around 350 worked better.

I’d recommend carrying out a proper steps per mm extrusion test to get the right amount of extrusion for what your 3D printer says it is extruding.

I made this Infinity Cube out of blue diamond PLA and it came out really well.

Creality Ender 3 S1 Review - Infinity Cube Blue PLA 1 - 3D Printerly

Check out this cool Spiral Vase from the same blue diamond PLA.

Creality Ender 3 S1 Review - Spiral Vase Blue PLA 2 - 3D Printerly

The layers are pretty much perfectly extruded from top to bottom.

I had to try out some PETG of course, starting out with an XYZ Calibration Cube. The layers adhered nicely, along with the lettering. There were some imperfections at the top of the cube though. I didn’t have ironing on so I’m not too sure why it happened.

Creality Ender 3 S1 Review - XYZ Calibration Cube Red PETG - 3D Printerly

This is a really cool looking 3D Benchy!

Creality Ender 3 S1 Review - 3D Benchy Red PETG - 3D Printerly

It did come with some stringing, but I figured afterwards that an increased Retraction Distance of 1.4mm (from 0.8mm) worked better with the retraction test I did. I also used a Retraction Speed of 35mm/s.

Creality Ender 3 S1 Review - 3D Benchy Red PETG 1 - 3D Printerly

This is a test cat made from black TPU that was on the USB. A little stringing and some blobs, but still successfully printed. Dialing in the retraction should fix those imperfections up.

Creality Ender 3 S1 Review - Test Cat Black TPU - 3D Printerly

This Flexi-Fish 3D print made from black TPU printed brilliantly. Very nice adhesion and it flexes properly. This had the same settings as the cat above, but since the print had a simpler geometry and fewer retractions, it didn’t have as much stringing.

Creality Ender 3 S1 Review - Flexi Fish Black TPU - 3D Printerly

I had all types of successful 3D prints right off the bat with the Ender 3 S1, most of which without even doing much tuning. The stock model prints awesome models which is a great feature to know before purchasing your own.

Check out this Part Fitting Calibration called the S-Plug made from PETG. It’s good for testing under/over extrusion, similar to testing your extruder steps per mm.

I did this awesome Elon Musk 3D print from MyMiniFactory in ERYONE Marble PLA after these prints with a 0.2mm layer height.

Creality Ender 3 S1 Review - Elon Musk in Marble PLA - 3D Printerly

Here is Michaelangelo’s David Statue in a 0.12mm layer height. I increase the Z-support distance so the supports were further away from the model to make them easier to remove. You can see some slight imperfections at the back, but this can be cleaned up with some sanding.

Customer Reviews on the Ender 3 S1

At time of writing, the Ender 3 S1 (Amazon) is still fairly new so there aren’t many customer reviews on it. From what I’ve seen, the reviews are mostly positive and people appreciate the new features that Creality have added to this machine.

I haven’t tried printing with ABS, but someone who had the S1 said they are producing ABS prints that are pretty much perfect. This is with a semi-enclosed environment with a small gap, the cooling fan off, and some adhesive used on the print bed.

Another user who had been using the S1 consistently for about a week said they really liked it. Comparing the S1 to their V2, they said the V2 feels quite cheap in comparison. They prefer the S1 a lot more due to all the excellent upgrades that most people have been craving.

One user commented that she had just bought one and found it very easy to set up, but they had an issue with the screen not loading and just showing the word Creality.

I’m not sure if this was fixed since it was just a comment, but this seems like a quality control issue, though it doesn’t seem like a pattern.

Another comment talked about the filament runout sensor working great, but the power loss recovery damaging the build plate after trying to resume the print. My one worked fine, so this may be an uncommon issue.

There was a really glowing review with someone mentioning that they couldn’t say enough good things about this printer. The assembly was very easy and they loved the design of the machine even more than other Creality 3D printers.

They found the leveling process very simple, even as a first-time user and they loved the storage tray built into the printer. After trying many types of filaments such as PLA, PLA+, TPU & PETG, they have completed plenty of prints successfully, along with a 12 hour+ print without issues.

In terms of noise, they said it’s incredibly quiet and the only thing you can hear running is the fans, which is pretty quiet altogether.

There are some great video reviews out there on the Creality Ender 3 S1 which you can check out below.

3D Print General Review

BV3D: Bryan Vines Review

Ender 3 S1 Vs Ender 3 V2 – Basic Comparison

A common comparison that will be made is choosing between the Ender 3 S1 and the Ender 3 V2. Both of these machines are going to work pretty well out of the box, but there are some key differences that will make it an interesting choice to choose between.

The main difference has to be the price. The Ender 3 S1 is currently priced at around $400-$430, which I’m guessing will start to decrease over time similar to previous Creality 3D printers. The Ender 3 V2 is currently priced at around $280, giving a $120-$150 difference.

Now what differences do we have in actual features and parts?

The S1 has the following that the V2 doesn’t have:

  • Dual Gear Direct Drive Extruder
  • Dual Z Lead Screws & Motors with Timing Belt
  • Automatic Leveling – CR Touch
  • Coated Spring Steel Bed
  • Filament Runout Sensor
  • 6-Step Assembly, Coming in 3 Main Pieces

Basically, the Ender 3 S1 is a highly upgraded machine right out of the box, allowing you to get straight into printing without having to worry about doing much tinkering, but at a premium.

One of the key upgrades is the Direct Drive Extruder, allowing you to 3D print flexible filament at high speeds. Currently, the new extruder cannot be bought separately and added onto the Ender 3 V2, but maybe there will be some kind of upgrade kit in the future.

One of my favorite benefits of this extruder is just how quick and easy it is to change filament.

Simply heat up the nozzle, manually push the lever down, push a little bit of filament out of the nozzle, then pull the filament out.

If you wanted to get the Ender 3 V2 and do upgrades, you could get something similar to the S1, but you have to factor in the time (and potential frustration) it takes to upgrade it. This comes down to preference.

Me personally, I’d rather get the upgraded model that works without me having to do any extra work. I only want to put some filament in, do a few calibrations and get to printing, but some people enjoy the tinkering side of things.

You also get an extra 20mm of height, with the 270mm Z axis measurement on the S1 versus to 250mm with the Ender 3 V2.

Treat yourself with the Ender 3 S1 from Amazon today to create some high quality 3D prints!
