xTool Studio Update, October 2025: Generators, Smart Nesting and Batch Fill

Back in October 2025, xTool Studio added a set of free tools that make it really easy to make something quickly: an Earrings generator, a Keychain generator, a Box generator, Smart Nesting and Batch Fill. I tested every one of them on my F1 Ultra and actually made the items, so you can see how they turn out.

This guide covers what that update added and how to use each tool. Studio has moved on since, so I've flagged where things look different now. For the newest features, see my latest xTool Studio update guide.

Where to find the new tools

Start a new project, then look at the toolbar on the left. In the version I filmed, the icon with three squares and a diamond opened Applications. Alongside the familiar tools like Grid array, Circular array and Material test array, you'll find Smart nesting, Batch fill and the Earrings, Keychain and Box generators.

What's changed since: in current versions of Studio this panel is called Useful tools and generators. Smart nesting, Batch fill and Material test array sit in its Efficiency Tool section, with the generators in the Generator section below. The Home screen now also has Atomm Discover, where you can browse all the generators in one place.

One thing to do before you use any of them: set your material. I used 3 mm basswood plywood and picked it in the material library first, because that's where the generators pull their settings from.

1. Earrings generator

Who doesn't need a new pair of earrings? This one gives you a list of templates down the left. Some of the pictures show acrylic and some show wood, but that doesn't matter, because you apply your own material settings.

1. Open Earrings generator and pick a template. I went for the football (American football, for my friends in the US).
2. Use the options on the right. On the football you can change the Number and the Hole size, which is the hole at the top for the hook or ring. Other designs, like the flower, have a Style option with preset shapes.
3. Click Import to Canvas. It comes in big, so drag a corner handle or type a size at the top to scale it down.
4. Check the hole size after scaling, because it scales with the design. I set mine back to 2.5 mm.

Click away and you'll see the score and cut parts are already set up. Because I chose my material first, the settings were filled in for me. You can still use One-click set to change them.

2. Smart Nesting

If you want to make lots of something, you don't want to drag every piece into place. I copied my earring ten times (Ctrl+C, Ctrl+V), selected them all, and used Smart Nesting to pack them in using as little material as possible.

1. Select all your items and open Smart nesting.
2. Set the Sheet size. The default of 600 x 600 mm is far bigger than my laser, so I set 150 x 150.
3. Under Other settings: Auto-Rotate turns pieces to fit better, Auto-Ungroup splits groups if it needs to, and Treat contained elements as a whole keeps each design together.
4. Click Start nesting.

Zoom in and you'll see tiny gaps between the cut lines. It does a really good job. It also works with a mix of different items, not just copies of one.

What's changed since: Smart Nesting was overhauled in the November 2026 update. Instead of typing a sheet size, you now draw the area to fill (or use Extract outline), choose Standard, Compact or Matrix, and there's a new Auto fill option. I've covered the new version step by step in the latest update guide.

3. Keychain generator

This works just like the earrings. Click through the templates and pick one. I chose a phone stand keychain.

1. Click the Style box for a list of ready-made logos. I picked a trophy.
2. Type your text. I put my son's name, Arthur. The text scales itself to fit, which is really clever.
3. Turn the Hanging hole on or off and choose a font under Font-Text.
4. Click Import to Canvas.

I wanted two keychains and two pairs of earrings, so I selected everything and ran Smart Nesting again at 175 x 175 mm. It doesn't matter that the items are different. It arranged them all neatly.

Cutting them out

I used the F1 Ultra cutting plate. If you don't have one, make sure your material is raised slightly, so when the laser cuts through it doesn't burn the surface underneath. I pushed the plywood against the back to keep it straight, focused the laser and framed the job.

I kept the default settings to see how they did. It cut every single piece, even the ones nested close together, but the default did six passes on the cuts, which was too much and left them a bit charred. That's why running your own material and cutting test is so important. My free Laser Settings Library is a good place to start, and you can find tested F1 Ultra settings on the F1 Ultra settings page.

4. Batch Fill

This is my favorite of the lot. It lets you engrave the same design on several items in one go, even when they're not lined up neatly. I put four bamboo keychains on the bed at deliberately awkward angles to see how accurate it is.

1. Place your items, focus the laser on one of them and update the camera view. Camera accuracy can vary, so expect it to be close rather than perfect.
2. Draw a rectangle (or another shape) around one item. I made it a red layer so it was easy to see.
3. Rotate it to match the item (mine was about 41 degrees). Turn off the aspect ratio lock so you can stretch it to cover the item completely.

4. Set the right material. I'd still got plywood selected, so I changed it to bamboo.
5. Select your rectangle, open Batch fill and click Frame out material first. Once it has recognized the shape, click Fill. It places a box on each of the other items.

6. Add your design. I used the Elements tab and picked a "Grab a beer" design, set it to engrave, rotated it to the same 41 degrees and centered it inside the box.
7. Select the design, open Batch fill again and click Fill. After a short wait the design is copied onto every item.
8. Turn off Output for the red boxes so only the designs engrave.

Batch fill needs an internet connection (the box says Network required). My job took 29 seconds.

Each one came out pretty much where it should be. One was slightly off, but overall it did a great job, and it's a really useful way to engrave several items quickly.

5. Box generator

Back to the 3 mm basswood plywood for this one. At the time there were five box designs, and each one shows you the cut path and how it goes together.

1. Set your material back to the plywood.
2. Open Box generator and pick a design. I chose a standard open box.
3. Set the size. Mine was 100 x 100 x 50 mm. You can add a pattern or a message, but I kept it plain.
4. Click Import to Canvas and check it fits on your material.

On the F1 Ultra the galvo laser moves from a central point, so the cut edges come out slightly angled. Even so, it cut most of the pieces cleanly and the box fitted together nicely. I was really impressed by that.

What I made in one session

Earrings, keychains, a batch of engraved bamboo keyrings and a box, all from these free tools. Once you've refined your settings, they're a really quick way to make something. Let me know in the comments on the video which tool you use most, and check the latest update guide to see what's been added since.
