Talk about an example of your own invention and write a 200-word composition.

3d printing technology is no stranger to everyone.

This is the most advanced technology today.

Attracted countless young people.

I am one of them.

So I bought a lot of parts online.

It took a long time to install this printer at home.

After many twists and turns.

Installed and dismantled, dismantled and dismantled.

Then consult the seller.

After several days of hard work,

Finally successfully installed this 3d printer!

The excitement is beyond words.

I didn't sleep well all night,

Then buy raw materials.

I started the first operation according to the instructions on the computer.

Print out a small funnel.

This is the biggest gain of my life.

I made it myself.

Small white funnel.

Very delicate.

The advanced science and technology is simply amazing. !

I jumped for joy.

How about 3d printing,

Bring me happiness.

Brought me glory.

I am willing to continue to invent and create.

Worthy of my youth,

I am in a very happy mood.
