There are many modern day machines that were only available for commercial use in the decades prior, today however it's an entirely different story, mobile phones that have computers in them are commonplace and other technologies have flourished to the point where we have wireless appliances for about everything. The number of innovations that have been made in the past few years have made many different products available to the general public. One of the more recent innovations is the 3D laser engraving machine which isn't as recent as it may seem. Lasers have been used for carving, cutting and engraving to a variety of materials.
Modern laser engravers much like 3D printers are pretty complex in the software department while being fairly simple on the hardware end. The number of different designs is only limited by your creativity and the engraver's flexibility and power settings. Your standard engraver can be used on a variety of different materials that range from wood to plastic to some metals (the last one isn't really suggested). Due to the nature of a laser 3D machine you can make extremely accurate engravings and cuts which the laser can also shadow and gray on its own depending on how you program it.
Much like the 3D printer your standard laser engraving machine is being primarily used by DIY enthusiasts around the world. The creations one can make with both these tools at hand are to numerous to list in one simple article. With the wide variety of models one can make they've also become popular with artists and 3D modelers that like to see their creations come to life in a relatively simple fashion. However, this equipment isn't a toy it can and will cause serious damage to your skin and eyes if they're exposed to the laser beam, so remember to wear plenty of protective equipment when operating the laser 3D machine. In combination with a 3D printer this can essentially become a parts and decrations manufacturing machine combo which would be fairly very cool if it didn't break the bank.
Lastly come the problems that arise with setting up two things that cause many different fumes to be exhausted out. If you don't have them in a well ventilated area it could lead to a fairly toxic gas building up in the room, so ensure that you either use the specific machines that exhaust the toxic fumes or be prepared to leave that room until the process is finished and the toxic gases vent out.
