Hi all,

I have recently purchased some 2020 T-slot profiles which are well made with a good finish and was just looking at V-slot prices for comparison.

The V-slot is 2-3 times the price, yeah it has a V profile but trying to understand why there is such a price difference?

I would assume volume at this point. T-slot is more widely used than V-slot, and V-slot seems to be relatively new.

Yep could be, would be interested to understand why. It is a unique product so guess they can charge what they like, I am just curious.

From what I can see the raw material and process is the same no matter if it's T-slot or V-slot, you just swap the die shape out to form the different profile.

I posted a reply to RatRig's advert HERE on the forum as they seem to be the only producer in the EU, see if they can shed some light on the question.

What prices are you discussing. How can someone recommend a source if they don't know what expensive means to you?

Hi cwaa,

My second post actually links to some prices I compared, however I am happy to provide a link to some 2020 T-slot for reference.

I purchase from Open Builds and I can get a 250 mm 20X20 v-slot for $3.00 plus shipping. A 1000mm 20X20 for $10.00. That seems reasonable to me.
I used to work in an extrusion operation. Die changes are very costly and create downtime on very expensive equipment. So longer runs are better and less costly per/foot. So volume will have a lot to do with price.
When I built my printer I was pleasantly surprised at the cost of the extrusions. I used mostly 20X80 v-slot. What set me back was the cost of the double ball bearing rubber wheels, and I needed 16 at about $5.00 each.
