In people's minds, 3D printing seems to have been tied to the word “rugged and durable.†This situation will change: Harvard University made a new composite material using 3D printing technology, which is lighter than wood. It's harder than concrete.
In general, the greater the density of the material, the greater the strength, but Barsalm is an exception, thanks to its high microstructure efficiency. Scientists are inspired by Balsa-Massachus, using a 3D printer to make this composite material into a honeycomb structure, which greatly increases strength.
According to reports, the new technology used epoxy resin for 3D printing for the first time, and uses nanoclay flakes to enhance adhesion, in addition to silicon carbide and carbon fibers as fillers. By changing the orientation of these fillers, scientists can freely control the strength of the material to meet various needs. This is a very desirable material.
According to the researchers' ideas, the new materials will be used to make lighter cars or planes so that they can run faster.
Drop-in kitchen sinks, also called self-rimming sinks, overmount sinks, or top-mount sinks, are sink basins that install and sit on top of your kitchen counter. There is a visible rim or lip on the perimeter of the basin that rests just over the cut-out for the sink. Drop-in sinks are supported by this lip and a series of hidden clips that attach to the underside of the countertop.
The Advantages of Drop-In Sinks
Drop-in sinks have some clear advantages over other styles, especially in the kitchen.
Cost
They`re generally cheaper to buy and easier to install than undermount sinks. In fact, even weekend warriors and DIY newbies should have no problem installing a basic overmount sink. If cost is a consideration in your kitchen, an overmount sink with a do-it-yourself install is a great way to stay within budget.
Cleaning
While cleaning may not be your foremost concern when choosing a kitchen sink, it should be considered. After all, you`ll have to care for and maintain your sink regularly. The basin of an overmount sink is easier to clean than the basin of an Undermount Sink.
Protection
If you`ve got soft countertops, drop-in sinks can help protect the edges of the sink cutout.
- Marble and some specialty counter finishes benefit from the added protection provided by the lip of a drop-in kitchen sink basin. It prevents the build up of water on the surface edges of the stone through repeated exposure of use.
- If you have laminate countertops, drop-in sinks are the only option: the particle board below the laminate surface isn`t strong enough to support undermount sinks but plays well with self-rimming basin types.
