Shadowless Pen Design

After 16 years of graduation design, it seems that the slot is full now. It doesn't matter. At that time, I compared the shaft and did not find a manual factory. I printed the effect of polishing and painting myself. Later, I really couldn't bear to look straight at it. At least I graduated. A pen with a glowing head can be used for construction, outdoor and other special occasions. It can write normally in harsh light environment (of course, it is much more convenient to write a diary in a quilt)

In order to emit light, I bought several diodes.➕AG0 battery, 3d printed a small slot, finally lit up

I tried to print it with fdm, but the quality was still a little poor, and then I switched to sla.

Rough demo

Spray primer

Find a very good paint and try spraying it.

It's lit up, and the surface treatment really can't be on its own.

Can't look closely

Several plans before the preliminary finalization

Stay up late to catch up with work.

Looking back at the previous rendering, I felt no good and uncomfortable. Two more.

It's not your problem that 3d printing can't render the effect, it's the material problem.

Yes, when time is thinking about saving money. In the following years, I have made a screwdriver, which is directly milled with cnc and then sandblasted. The effect is much better, but the thief is expensive!

Powder metallurgy can also be used for proofing.

I can't afford it. It was still 16 years at that time. Laser sintering was too expensive! It took me less than 200 before and after this.

It was true that 3d printing was twice as expensive as it is now.
