Why Choose the eufyMake E1 Rotary UV Printer?

The eufyMake E1 with Rotary Attachment is built to save you time while giving you incredible results.

It's fast, precise, and makes your creative process smoother than ever.

Let’s explore the standout features that make this machine an essential tool for your shop.

Smart Auto-Leveling Saves You Time

Getting perfect prints on curved surfaces used to require tedious manual measurements and adjustments. Not anymore. The eufyMake E1 uses dual laser sensors to automatically measure your cup's height and shape.

This auto-leveling feature means you never have to guess the correct print head distance. The system calculates the perfect position every time, ensuring your ink lands exactly where it should for crisp, consistent results.

Print on All Popular Sizes

One of the biggest questions we hear is "Can I print on different sized tumblers?" The answer is yes.

The eufyMake E1 rotary attachment works with cups between 80mm and 245mm tall (roughly 3 to 9.6 inches), with diameters from 45mm to 100mm (1.8 to 3.9 inches).

This covers most standard sizes on the market today, including:

  • 12oz tumblers (approximately 95mm tall)
  • 20oz skinny tumblers (approximately 210mm tall)
  • 30oz tumblers (approximately 240mm tall)

Just adjust the attachment to fit your specific cup size and you're ready to print.

Free, User-Friendly Software  

You get full access to eufyMake Studio, our dedicated RIP software, at no extra cost. The interface is designed to be intuitive even if you've never used a UV printer before.

It works seamlessly with both Windows and Mac, giving you the flexibility to use the software that fits your setup.

How to UV Print on Tumblers: Step-by-Step

If you want to print on a tumbler with the eufyMake E1, the process is easier than many people expect.

Here is a clear step by step guide you can use.

Step 1: Clean and Pre-treat for a Pro Finish

First, wipe your tumbler with 75% alcohol to remove dust and fingerprints.

If you are printing on glass or shiny metal, apply a UV coating (pre-treatment) to make sure the ink sticks forever. For a perfect look, apply a little masking tape to the top and bottom edges. This keeps the edges of your design sharp and clean when you peel it off later.

Next, prepare your design file. Use a high resolution image and size it for the printable area of the tumbler.

If you want the graphic to wrap around the tumbler, it helps to check the layout before you move to printing.

Step 2: Install the Rotary Attachment

Switching is fast. Slide the latch on the printer tray to the left and lift out the flatbed.

Place the Rotary Printing Attachment onto the tray, then slide the latch back to the right to lock it in.

If you are printing a skinny tumbler with deep threads inside the top (more than 15mm), use the strut spacer to make sure the cup sits in the right spot.

Step 3: Load the Item onto the Drive Wheels

Hold your tumbler with the opening facing left and push it against the front stop pin. Place the opening on the drive wheels.

Press the unlock button and slide the end until the rear stop pin is snug against the base of the cup.

Rest the bottom on the follower wheels and slide the adjustable strut to the right to lock it in place.

Step 4: Let the Software Take Over

Next, open the eufyMake Studio RIP software on your Mac or PC.

Within the canvas interface, click on Print Bed and select Rotary.

Instead of using a ruler, just click Auto Measure and select the shape of your cup.

The E1 will use its dual lasers to automatically measure the height of the item. This ensures the print head is always at the perfect distance, which is critical for a high-quality finish.

Step 5: Position Your Design and Print

Upload your image into the workspace. The software will show you a 3D preview of your design wrapping around the cup, so you can see exactly how it looks before you waste any ink.

You can manually adjust the top and bottom margins to get the placement perfect.

Once you’re happy, hit print! The printer precisely coordinates the rotation and the print head to create a seamless, 360-degree wrap.

Step 8: Check the Finished Tumbler

After printing is done, inspect the tumbler carefully.

Look at the placement, edge clarity, and overall print quality. Make sure the design sits where you expected and that the result looks even across the printed area.

If needed, compare the finished print with your software preview so you can fine tune future jobs more easily.

Printing on Mugs, Slanted Cups, and More 

The eufyMake E1 isn’t limited to standard tumbler shapes. Here’s how it handles tricky items:

  • Mugs with Handles: Use the "With Handle" mode in the software, which ensures the printer knows where the handle is so it doesn’t interfere with the design.
  • Slanted or Tapered Cups: Tilt the rotary attachment up to 13 degrees to keep the print surface level, ensuring clear, crisp textures.
  • Lightweight or Small Items: If your item is too light, fill it with a little water to add weight and ensure smooth rotation. For items with odd-shaped bottoms, use the provided Follower Wheel Bushing for stability.
