3D Crystal is a company that makes a unique type of keepsake: three-dimensional laser etched images in optically clear crystal. Using a high-quality green laser, your photo is modeled into a three-dimensional design that’s engraved in the crystal, creating a truly stunning keepsake that will be treasured forever. The crystal itself is made from K9 crystal (a type of optical borosilicate crown glass used to make photographic, telescopic and microscopic lenses) that’s durable enough to be displayed in a high-traffic area.
Customers rave about how much they love the quality of this product and how well it stands up to the test of time. The company also offers a money-back guarantee, which is a good sign that they’re willing to put their reputation on the line.
The 3D Crystal company has a solid rating of 4.8 stars out of 5 on Amazon and is a great choice for those looking to buy a gift for someone special or even themselves. The product is a little pricey, but it’s worth every penny when you consider how long-lasting and beautiful the results are. This product is a must for anyone who wants to preserve memories for a lifetime.
A three dimensional (3D) printed molecular model can be an effective tool to help students learn about chemical structure, bonding and interaction. These models can be built using a variety of different types of materials, including Styrofoam beads, plastic molecular model kits and 3D printers [1]. The advantages of 3D printing are that it allows for the creation of complex structures that are not possible with traditional modeling constructs. 3D printed molecular models can also be manipulated and disassembled, providing students with an opportunity to experiment with the behavior of these systems.
A variety of methods exist for programmatic conversion of crystal structures into 3D printable files including web tools and the stand-alone Cif2VRML application. However, there are still limitations in this process due to the fact that many crystal structures contain counter ions and solvent molecules, which would need to be removed prior to 3D printing. In addition, 3D printed crystal structures are often asymmetric and require careful consideration for the removal of hydrogen atoms in the structural model to achieve maximum stability during printing.
