Canadian researchers have developed a new 3D printing method called blurred tomography that can rapidly produce microlenses with commercial-level optical quality. The new method may make it easier and faster to design and fabricate a variety of optical devices.
"We anticipate this method to be valuable for cost-effective and swift prototyping of optical components due to the affordability of the tomographic 3D printer and the materials used," said Webber."Also, the inherent freeform nature of tomographic 3D printing could enable optical designers to simplify designs by replacing multiple standard optics with printed optics that have complex shapes.
They also made a 3x3 array of microlenses using blurred tomography and compared it to an array printed with conventional tomographic 3D printing. They found that it was not possible to image a business card with the array printed with conventional means due to large surface roughness, but it could be done with the array printed with blurred tomography.
"Tomographic 3D printing is a rapidly maturing field that is finding use in many application areas," said Webber."Here, we leverage the intrinsic advantages of this 3D printing method to fabricate millimeter-sized optical components. In doing so, we have added to the repertoire of optical manufacturing techniques a rapid and low-cost alternative that could potentially have an impact in future technologies.

Apple Researchers Develop Text-Based Photo Editing ModelApple researchers have collaborated with the University of California, Santa Barbara to create a new model that allows users to describe desired changes in a photo using plain language. The MGIE model, short for MLLM-Guided Image Editing, enables users to crop, resize, flip, and add filters to images through text prompts. It can handle both simple and complex editing tasks, such as modifying specific objects or enhancing brightness. The model combines the interpretation of user prompts with the generation of corresponding edits. Users can simply type out their desired changes to edit a photo with MGIE.
