Accurately Painting 3D-Printed Objects By Dipping Them in Water

How do you paint a weirdly shaped 3D-printed object with a complex pattern? Take it for a dip in the pool.

A new color technique pioneered by researchers at a computer graphics and visualization lab at Zhejiang University [PDF] involves dipping an object in water while coating it in a multi-colored film. This paints the object in one stroke with zebra stripes, leopard print, or whatever other pattern you might want.


It builds on a process called hydrographic painting, which, while similar in concept, isn't terribly effective. The plastic film floated on top of the water, and it was meant to stretch across the dipped object. But it often went awry, creating an inconsistent splash of color or even tears in the paint.

Instead, computational hydrographic printing involves creating a 3D scan of the object (say, a mask) before it's lowered into the water. An algorithm takes into account the way that the plastic film will bend and distort as the object is lowered onto it by a robotic arm, drawing the pattern accordingly. The pattern is then printed out on a regular office printer and then placed on top of the pool of water. The result is a perfectly glued-on pattern, every time.

By dipping the object in the pool multiple times, you can even create a texture to the paint, as if it was painted by hand. (In case you needed to pass off some mass-produced 3D printed wares as homemade Etsy items.)

Want to Boost Your Home's Value By More Than $6000? Paint Your Front Door Black

If you're looking to sell your home, you may want to take some advice from The Rolling Stones and paint it black. Just the front door, that is. That's because front doors in shades of black or charcoal tend to raise a home's value by $6271, according to a new analysis by real estate website Zillow.

"For a seller, painting a front door is one the least expensive home prep projects, but also one that can have a powerful impact on a home's sale price," Kerrie Kelly, a home design expert for Zillow, said in a statement.

However, this may have more to do with the contrast than the colors themselves. Kelly said more subdued hues like beige and light blue are still popular, but real estate experts have seen a trend toward "pops of color, particularly in darker hues" like dark blue, gray, and black. "Contrasting colors, especially in kitchens and home exteriors add interest and dimension to a room that plays very well in listing photos and videos," Kelly says.

Also popular are "tuxedo kitchens," in which the countertop and upper cabinets are either black or white, and the lower cabinets are painted in contrast. That design scheme can raise a home's value about $1550, Zillow reports.

For its 2018 Paint Color Analysis, Zillow looked at more than 135,000 photos of homes sold across the country between 2010 and 2018 and compared their closing prices to those of similar homes with white walls. In doing so, they were able to conclude which color schemes are considered most valuable.

Other paint jobs that can hurt a home's value include yellow exteriors, brown dining rooms, and red kitchens (red in general is said to be an anxiety-inducing hue, so it's best to use it sparingly in homes). On the other hand, light blue bathrooms and light taupe living rooms are an asset.

If you're hoping to sell your home but don't plan to do so for another few years, it's best to hold off on repainting, if possible. Tastes in color schemes are constantly changing with the times—just two years ago, Zillow recommended yellow kitchens and purple dining rooms.

Syrian Refugees and Jordanian Women Created a New Line of Home Goods For IKEA

After debuting the Tilltalande Collection at its Amman, Jordan location last year, IKEA is finally bringing it to the U.S. As Curbed reports, every item in the collection was created by women from Jordan and refugees from Syria.

The new line is a collaboration between IKEA and the Jordan River Foundation, a nonprofit dedicated to improving the lives of Jordanians, especially women and children. It includes a flatwoven rug and pillow covers decorated with elements like camels and blossoming cacti. Fifty Jordanian women artists and 50 Syrian refugees worked with IKEA to design the items and craft them by hand.

The Tilltalande Collection is the latest way IKEA is helping some of the millions of refugees forced from their homes by conflict. In 2015, the furniture company debuted its flatpack shelters, temporary homes that provide protection and electricity to displaced people around the world.

The new line of textiles will be sold at IKEA's Brooklyn location starting this June. If all goes as planned, the collection will provide employment to 400 people by 2020.
