Engraving Curved Surfaces with the F1 Ultra

Have you wanted to engrave designs on mugs or cups without using a rotary tool? With the xTool F1 Ultra laser engraver, you can easily add text and images to curved surfaces. Follow along as we walk through the setup. Let’s get started with simple steps to create personalized cups that look great.

Understanding the xTool F1 Ultra’s Capabilities

Engraving on curved surfaces like mugs or cups can be difficult. Typically, this requires a rotary attachment to spin the item during engraving. The xTool F1 Ultra solves this problem with its curved surface engraving feature.

This is a newer feature that adjusts the laser’s focus automatically, keeping designs clear on rounded items without extra equipment. It wasn’t in the laser’s firmware when it was initially released, so a lot of early reviews miss this feature.

How Does the Curved Surface Feature Work?

The curved surface feature uses the laser to measure the distance on points of the object’s surface, then maps that curvature to a mesh grid.  The laser will auto adjust itself as it engraves so the design doesn’t falloff around the curve.

You’ll be able to engrave on one side of a cup or mug (you can flip the mug over and engrave on the other side.) To do a full wrap around you’ll still need a rotary tool.

Step-by-Step Guide to Engraving a Mug with the F1 Ultra

1. Set up your mug in the machine.  Curved objects tend to roll, so you’ll need to stabilize it on its side.  You can use a jig if you have one available.  We just used one of the foam pieces that came with the laser and nestled the mug inside.  You could also use a container of sand or rice to keep it stationary.
2. Align the laser. Use the up and down buttons to make sure the red and blue dots overlap on the object’s surface.
3. Open a new project in xTool Creative Space (XCS) for your design
4. Choose “curved surface” instead of the default ‘flat surface’ setting
5. Walk through the steps to scan the object’s surface and set the points in your grid.
6. Make sure your design in placed correctly on the object. You can see the blue outline in the photo below shows where the design will go. For the mug, an image size of around 55mm fit best for us.
7. Choose your laser settings. For a plain white mug (with marking spray), we use these settings: Laser: Blue Diode Mode: Engrave Power: 50 Speed: 300
8. Use the Framing feature to make sure your design is correctly positioned
9. Run the job. Press start and watch as the laser carves your design.
10. Check your results, but DON’T move the mug.  If you need another pass, you can run the job again as long as you’ve not moved anything.

Engraving on other types of cups, tumblers, glasses, or bottles follow the same process. For any kind of glassware, you’ll need to use marking spray or paint (else, the laser just shines through the glass.) We use this marking spray.

Here’s a 40 oz Stanley-style tumbler and a smaller 20 oz tumbler.

You don’t need to stick to mugs and drinkware with the curved surface feature. We engraved the inside part of a wooden spoon. Mapping out the curve and mesh are the same process as we detailed above. You can see the blue lines in the image below framing up where the design will go (the laser is drawing the square too fast for the shutter speed to catch the whole square!)

Check out the video to see how the laser tracks the curve and see what the finished engraving looks like:

Here’s a wine bottle fresh from engraving. They grey color is the marking spray used so the laser doesn’t pass right through the glass.

Laser Engraving Project Inspiration and Ideas

Engraving mugs or glasses with the Xtool F1 Ultra opens up lots of creative and practical uses. Whether you want to make gifts, run a fundraiser, promote a brand, or sell products, mug engraving offers a fast and easy option. Below are a few project ideas with clear purposes and wide appeal:

• Personalized gifts. Add a name, birthday, or short note to create a one-of-a-kind present. These work well for holidays, graduations, or thank-you gifts. People enjoy using items made just for them.
• Custom business items. Engrave a company logo or short message on mugs to give to staff or clients. Branded mugs make great promotional tools at events or in the office.
• School and team spirit. Create mugs for students, teachers, or fans using mascots, team names, or graduation years. These can be sold at school events or given as awards.
• Motivational quotes. Short phrases like “Stay strong” or “One step at a time” add daily inspiration. Use clean fonts and center the text for a simple, bold look.
• Holiday themes. Design mugs with snowflakes for winter, hearts for Valentine’s Day, or pumpkins for Halloween. These can be used as seasonal decor or thoughtful gifts.
• Fundraisers and events. Sell mugs engraved with your organization’s name or a special event title. They work well for raising money or as thank-you gifts for supporters.
• Functional designs. Mark mugs with fill lines, temperature warnings, or dishwasher safety icons. These are useful in settings like offices, workshops, or shared kitchens.
• Art and patterns. Simple line drawings, nature shapes, or repeating patterns create a clean, modern style. Engraved art mugs can be sold online or at craft markets.

Stick to high contrast, clear designs for the best results.
