Creality adds a lower-cost resin printer to its range

Creality has added an entry-level 2K monochrome resin machine to its 3D printer range. Resin printers create solid objects from a vat of liquid photo-polymer using ultra-violet patterning. In the sub-£1,000 market, these printers have rapidly converged to designs where the active layer of the print is at the transparent bottom of a vat, illuminated from ...

TSMC building huge water treatment plant

TSMC is building a water purification plant in Tainan to come on-stream at the end of the year. The plan follows Taiwan’s worst drought in 50 years. The plant will be for TSMC’s sole use and will process re-used industrial water for its fabs. According to TSMC the plant will be the world’s first such advanced ...

Compostable plastic invented at Lawrence Berkeley

Scientists at Lawrence Berkeley National Laboratory have designed an enzyme-activated compostable plastic which can be broken down by household tap water or soil composts into reusable small molecules, called monomers, in just a few days or weeks. Most biodegradable plastics are made of either polylactic acid (PLA) or polycaprolactone (PCL) which take months to break ...

UV modulation by twisting crystal films

Films of the two-dimensional material hexagonal boron nitride can be used to control light emission from materials, according to the Singapore-MIT Alliance for Research and Technology (Smart). The phenomenon involves the creation of ‘Moiré superlattices’ as two films are rotated with respect to one-another, and works at room temperature with films made from stacks of atoms around 100nm ...

Particle physics maths rescues laser array mode locking

How can anyone persuade an array of lasers to emit a single-mode coherent beam? was the question being asked by a team of US researchers. “One seemingly straightforward method to achieve a high-power single-mode laser is to couple multiple identical single-mode lasers together to form a laser array,” said University of Pennsylvania scientist Liang Feng. ...
