Modular Furniture Makers

[nsbb123]

Pardon me for my ignorance....
First of all I want to ask what is meant by modular furniture ?
Can Carpenters make them or is it done only by Hot Press Machines and Edge Banding etc etc

Why is there a cost difference between man and machine made?
Which is more efficient?
Machine made ofc looks more standard and stylish
Man made has a lot of pointy edges and there are discrepancies around if not done 100% perfect

Can anyone suggest me a JOB Work Company where in I can purchase material and give it to them
for processing it ? in Bengaluru ofc kanakpura area

Thanks
