Engraving a tumbler is not as simple as engraving a flat surface. You are not working on a simple plate or sheet. A tumbler typically has a circular surface, which needs special attention. Choosing the right laser engraving machine for tumblers is crucial here.
When you are engraving tumblers, you cannot just place them under the laser and press start. You need a rotary attachment to rotate the tumbler while the laser works. This way, the laser gets access to every part of the curved surface.
If you do not use the rotary attachment, the engraving will be distorted or uneven. You must also adjust the engraving parameters to match the materials of the tumblers. You might be working with stainless steel, powder-coated, colored coating, or plastic. Each material needs unique laser settings.
This article will guide you through the basics of laser engraving machines for tumblers. It also highlights why you need a rotary attachment. Most importantly, it teaches you how to laser engrave tumblers.
Introducing the Laser Engraver for Tumblers
A laser engraving machine for tumblers is typically made for engraving cylindrical objects. It looks almost similar to a regular one. However, it needs an extra device called a rotary attachment, which rotates the attached object. This way, the laser gun can get access to all areas on the curved surface.
The rotary attachment holds the tumbler securely and slowly spins it. The spinning tool and the engraving work are done sequentially. You will learn more about it in the next section.
A regular laser machine does not have this tool. It only works on flat surfaces. Because of this, regular laser engravers may cause distortion when they work on curved surfaces.
The tumbler engraving machine can also work on other cylindrical objects. You can use it for bottles, wine glasses, metal cups, and many more. You can use it for both personal and business purposes.
Pros
- Works perfectly on curved and cylindrical surfaces
- Provides high precision and consistent engraving
- Highly versatile, works on stainless steel, aluminum, and coated surfaces
- Suitable for all kinds of projects
- Supports detailed artwork, text, logos, and custom designs
Cons
- Needs a rotatory attachment, which adds extra cost
- Requires correct parameter settings for each material
Introducing Laser Engraving Rotary Attachment
To engrave tumblers, bottles, or mugs, a rotary attachment plays an important role. It works by attaching the object and moving along the design. Usually, it holds the object with a chuck or roller. But the primary function of this device is to rotate the object while engraving. Thus, it helps to create a precise engraving over the whole body or the required areas. In comparison, this method is both flawless and the best way to engrave cylindrical objects.
The working principle is quite simple. Here, the attachment holds the tumbler and turns it step by step in sync with the laser beam. In this process, speed and direction are controlled by the laser software. This feature makes the design wrap more evenly on curved surfaces.
Control features are critical for proper accuracy and results. Attachments allow you to adjust everything according to your needs. You can fix up the diameter, grip, and speed, as mentioned earlier. But the crucial part is to match the speed with the engraving depth. So, make sure your rotational speed is sufficient to ensure proper etching depth.
There are other engraving parameters to consider. Such as machine power, resolution, and more importantly, line spacing to fit the material. Overall, using the right laser settings and rotating speed will always result in a smooth, sharp, and professional outcome.
How to Laser Engrave Tumblers
Laser-engraving tumblers may look simple. However, the exact process depends on the types of tumbler materials. It may be made of stainless steel, aluminum, plastic, glass, or even coated metals. Each materials react differently with the laser beam. For example, plastic may melt or warp, or glass may crack if you use the wrong laser settings.
When it comes to metals, you should also pay attention to the correct setup for both tumblers and the laser settings. Stainless steel is typically a reflective material. If you try to engrave it directly, the laser beam may scatter and fail to mark the surface. To solve this problem, you can use a spray or marking agent on the tumbler surface.
Assuming you are working with the stainless-steel tumblers. The steps below will guide you to create a high-contrast laser marking on stainless steel tumblers.
Step #1: Prepare Your Artwork & Material
To start the engraving, first create your design. You may make your own design with software like CorelDRAW, Illustrator, or other similar software. You could also use an existing design from online. However, you might need to customize it based on your preferences. Once the design is ready, preview the design and size for final tuning. In this case, you must make sure the whole design covers the curved surface of the tumbler.
The next step is choosing the right material for engraving. Note that different materials react differently with varying sources of laser. For example, a CO2 laser works great with non-metals and coated metal surfaces. On the other hand, fiber laser works perfectly on metals. Therefore, we always recommend that you think about the possible materials that you might deal with throughout your entire business projects.
Step #2: Spray the Tumblers
The second step is to prepare the surface for engraving. Using CO₂ lasers will yield better results if a marking compound is applied to the surface. Additionally, the coating assists the laser in creating a high-contrast, permanent mark on a glossy surface. Make sure the layer is even and covers the whole area.
If you use a fiber laser, you may skip the surface pretreatment. The reason is that it is designed to handle bare metal marking. This step is not required for fiber lasers. It can easily mark stainless steel without any coatings. Just ensure the settings are ideal for the approach.
Step #3: Set up the Rotary Attachment & Install the Tumbler
Lower your engraving bed to set up the rotary attachment. If you lower the bed, it consequently creates space for attachment. Press the power and turn it off. Thereafter, plug in the rotary unit and restart your system. As a result, the laser can properly reset its “home” origin for rotary operations.
Once the setup is done, place your tumbler onto the rotary. Use a level to make it horizontal, ideally. If your machine supports center-to-center focus, then use manual focusing. You may use a red dot pointer to align the center before setting a new home position.
Step #4: Adjust the Laser Parameters & Start the Process
Open your laser control software. Select these recommended settings to engrave stainless steel. Make speed 15%, Power 100%, and DPI 500. Use a 30W fusion maker system. Don’t forget to use marking compound if needed.
Send the job to the laser machine and start the engraving procedure. The system will automatically manage the speed of the tumbler’s rotation. It also manages the firing in sync. This way, you may achieve a prominent and even etching all over the curved surfaces.
Step #5: Rinse Off the Tumblers
Once your engraving is complete, gently rinse off your tumbler with water. It helps you to wash the surface if there is any residue due to the marking compound. You do not need any harsh chemicals or harmful substances to remove them. Plain water is enough to clean off the surface for a better view of the design.
After cleaning, leave it until it dries. The tumbler is prepared for use or gifting once it has dried. The contrast created by the compound, combined with the laser engraving, produces a clean, professional finish that highlights your artwork beautifully.
Laser Engraved Tumblers Market Opportunities
A laser engraving machine for tumblers opens many business opportunities. Many companies often order engraved tumblers in bulk for branding and promotions. Many team members use these custom tumblers as appreciation gifts to build relationships.
