Grape Leaf Scan on Home Built 3D Laser scanner - Scroll Saw Woodworking & Crafts Message Board

From a week i am working to improve my David Laser scanner setup.. Earlier, I have a stepper motor attached to 1:60 gear box..The output was very coarse with jerks so yesterday i made MDF bearing holders and grabbed teeth Belt and Pulleys from local market..After minor modification the output from the gear box further reduced to 1:7 with timing belt..Now i can scan with very high resolution..Attached is the low resolution scan from free version of David Laser scanner..Its smoothness and interpolation kept to one..You can see how small the object with details...
The green laser pointer was gifted by my friend Richard..i made a teflon attachment with a lens to convert it into Line laser...

Khalid your expertise and engineering skills amaze me. I could never begin to understand the workings of a laser printer.

Detail is great. What resolution is the scanner set to? I know some, but not enough to completely build a unit. Great work and thanks for sharing!

Thanks for all of you who posted.. Pardon to those who didn't understand ... Making computerised accurate 3D models can be done in two ways..

1- Start from scratch in a Drawing software and make a 3D model
or
Use a 3D scanner to scan an already built object that will automatically convert it into point clouds and Mesh..

3D scanner are very very expensive.. I did made one by using the backyard material and the software of David Laser scanner...

As for as resolution is concerned just see the details on the grape leaf..How precise is this... or check the details on the following Orange that i just pick up from the tree in my Lawn...

Keep plugging away at your hobby, a bit confusing to me, but I appreciate your enthusiasm.

The bi advantage for me is that i have a CNC Machine.,, I can scan and make them duplicate with CNC machine
