Selected!Ten Common Problems Of Laser Engraving


Apr 03.2018

Introduction: for different materials, laser engraving parameters and using methods are also different. How can we adjust these to achieve the desired results?


For long-term industry that uses laser engraving machine, or DIY fans, there will be more or less problems encountered in laser engraving. For different materials, laser engraving parameters and using methods are also different. How can we adjust these to achieve the desired results? This period brings you ten common questions about laser engraving, and provides suggestions for different materials and machine usage.


1. about real wood and hardwood carving suggestions?


When carving hard wood, we suggest covering up the surface of wood, so that the residue can be infiltrated into the engraving area and easy to clean.


Use the carving mode from "from bottom to top". In the laser software RDwork we use, we can change the working mode of the laser head, which allows you to engraving from the bottom to the top, not from the top to the bottom. The advantage of this way is that smoke and debris can be reduced into the engraving area when the laser head moves.


After carving, use some glue removing agent to clean it. Because the gum of hardwood will blacken when it burns at high temperature.


 2. really be carved in glass? What are the skills?


First of all, we should know that not all glass is smooth. Though you may think that you need to buy some more expensive and high-grade glass for better results, it's not actually the case. We have many customers who use wholesalers glassware to carve, but the carving effect is pretty good.



For the carved glass we give you a suggestion:


With relatively low resolution, as long as 300DPI can get better results.


Change the black in the figure to 80% black, which will improve the engraving quality.


We found that a wet towel on the glass can help to heat and improve the carving quality, but make sure that the paper is not wrinkled.


Using finger or paper towel to smear a thin layer of soap in the area to be carved is also helpful for heat dissipation.


Use ScotchBrite or similar items to polish the engraving area and remove glass fragments.


3., what do we need to pay attention to when carving on plywood (three plywood) or light board?


This material is more suitable for cutting, not carving, because the texture of plywood may be uneven, and there are different adhesive layers in it. And when you want to carve on it, the material is very important. Uneven, or too much glue will affect the carving effect. Of course, if we find better quality plywood, the effect of carving is very good, for example, wood engraving.




4., I want to expand my business scope to leather. Is it very difficult?


Laser engraving or cutting leather can be done, and many of our customers are engaged in this industry. They want to customize the LOGO of wallet and handbag.



5. what is the best set of engraving artificial leather?


It will depend on your machine and tile number, but you can find the laser parameter list at the website of Lei Yu laser website. If there is doubt, you can start your own test at relatively high speed and low power. Because if you don't move your material, you can sculpt it again until you get the desired effect.


6. I hate to waste materials. Can laser engraving machine make use of waste products to make cool projects?


Using waste is a very good idea, not only to create new projects, but also to use waste to test more challenging sculptures, such as photographs. We have seen many customers making all kinds of things with waste materials, such as small acrylic lighting signs, jewelry, labels and so on.


7., I have an apple computer. Can I use Lei Yu laser engraving machine?


Our system can run Windows based design software, and most of our customers choose CAD and CorelDRAW. MAC computer can't directly connect to our system, but you can install virtual machine to run windows, so that we can use our machine.


8. how to maintain my machine correctly? How long does it take to clean my Nova35 or Nova24?


GEM LASER provides a maintenance plan, which lists the items to be maintained and the frequency of the maintenance, which are described in detail in our user's manual. The most important maintenance items are the cleanliness of machines and the cleaning of optical lenses. The two is the cleaning of optical lenses. Clean optical lens helps to ensure that the laser produces the most accurate carving and cutting effect.


9., can I use laser engraving machine to make investment in the clothing industry?


This is affirmative. GEM LASER machine can cut and carve out all kinds of textiles directly. We have many users in carving jeans, hollowing cloth and so on.


10., can you recommend some cheaper materials to me?


We also have some relatively reliable material suppliers that can be introduced to you, but not very cheap.Eg: GEM LASER LIMITED
