Are you still worried about what gifts are best suited for your friends? Do you want to choose something creative to express your sincere wishes? With economic development, people now have more sophisticated requirements for presents. Gifts that can not only express best wishes but are also full of clever ideas are coming into sight.

Lots of my friends want to print their favorite pictures and cartoon characters on some small ornaments. People who are keen on DIY also wish to make their own electronic products using home-made PCBs. Due to these demands, the idea of making a laser engraving machine came into my mind. The machine is made almost completely from wasted materials, which not only saves money but also puts the concept of “resource recycling and reuse” into practice. However, the first generation of my laser-engraving machine can only satisfy the need of printing personalized pictures, but not etching the PCB. Thus, I expanded the machine frame size to create the second generation and came up with an innovative method of PCB etching, broadening the machine’s uses.

The machine is made from discarded CD-drives and printers – either taken from wasted home appliances or bought from the second-hand market for a few RMB. I will show my print work at the end.

你是否像我一样对送什么礼物给好友而感到烦恼?你是否像我一样希望挑选富有创意的礼物表达心意?随着经济水平的提高,人们对于礼物有了更多的要求,既要表达心意又要富有创意的礼物渐渐进入人们的视线。
许多身边的朋友也希望能够把自己喜欢的图形,动漫人物打印在一些小挂饰上,而DIY爱好者则更希望能够在家里自制pcb来制作一些属于自己的电子作品。基于这些需求,我萌生了制作激光雕刻机的想法。全套机器几乎都采用废弃材料,这一方面节约经费,另一方面践行了资源循环利用的理念。但是,第一代激光雕刻机只能满足打印个性图案的需求,却无法满足腐蚀电路板的需求,所以我在第二代产品中对机架进行扩大,并且创新性的提出了腐蚀电路板的方法,使机器的用途更加的广泛。 这个是我利用废旧光驱和废弃的打印机做的,都是从家里报废的东西上拆的或者是几块钱从二手市场买到的,最后我将附上我的打印作品

Step 2: (first generation) Using the CD drives – dissemble the wasted drive and take down the laser and stepping motor

The first step is to dissemble the wasted CD drives, taking the stepping motors and laser heads from them. The last picture shows the laser head after disassembly.

Step 3: (first generation) Assemble the circuits and the drive frames

This is my first-generation product, using the wasted CD drives and Arduino.

Let’s start assembling! This is the specific making process: solder the circuit board by Arduino Nano and a4988 stepper driver; use the waste wood slats and the disassembled drives’ stepping motors. Wood is not only easy for making changes, even with a saw or utility knife, but also environment-friendly. Always remember to keep the stepping motors on the x and y axes perpendicular to avoid printing crooked or skewed pictures.
