Overcoming the Absence of a Rotary Attachment for Cylinder carving: Achievable!
New Method for Laser-Engraving Cylindrical Objects Without Motorized Rotary Holder
In a groundbreaking development, Samcraft has demonstrated a unique method for laser-engraving cylindrical objects, such as mugs, without the need for a motorized rotary holder. This innovative approach, which splits the design into multiple separate engraving sections and uses manual rotation with a 3D-printed jig, offers an affordable and effective alternative to traditional methods [1].
The key to this technique lies in the segmentation of the design into individual elements or tall, thin segments. This approach works best for designs like line-art flowers or plants that don't require perfect alignment between segments. Once segmented, each portion can be engraved individually, without the need for continuous rotation [1].
During the engraving process, the mug is securely held in a 3D-printed jig that allows for precise manual rotation and repositioning for each engraving pass. This ensures repeatable positioning, eliminating the need for a rotary motor [1][2].
Samcraft found that engraving areas up to about 45mm wide on the curved mug surface maintain good laser focus. Larger areas could potentially suffer from focus loss due to curvature [1]. The method is suited for certain kinds of designs that can be split cleanly, but continuous or highly detailed wraps requiring precise, seamless continuity may be less feasible without a rotary attachment [1].
It's important to note that since the engraving requires leaving the laser enclosure partially open (to accommodate the mug and jig), proper laser safety precautions and eye protection must be strictly observed [1].
In summary, Samcraft’s approach avoids the complexity and cost of motorized rotary holders by combining segmented design, a 3D-printed manual rotation jig, and careful repositioning to engrave the mug fully all around using a stationary laser engraver setup [1][2]. The results of this engraving method are considered pretty nice.

- This innovative approach for laser-engraving cylindrical objects, such as mugs, involves the segmentation of the design into individual elements or tall, thin segments, and can be used with various gadgets like 3D-printed jigs for manual rotation.
- When it comes to ensuring laser safety precautions and eye protection during the engraving process, it's crucial to remember that this method requires leaving the laser enclosure partially open, making it applicable to a range of technology devices.
