Good.
Let's see if they will offer it at a fraction of the previous price and how other manufacturers will respond.

3D printing

Joachim
Think of a speaker cone with material formulation changing from center to periphery, cone-surround too as one-piece construction.

I have worked quite extensively with different types of rapid prototyping, To be honest the precision and the materials are not very good, the epoxy used in the Tonearm, is very prone to absorb moisture, and over time it warps, like a vinyl record subjected to heat. there are some materials that performs a bit better and some additive laser based sintering that can produce quite good parts, but there you also have to pay the bill. I made an arm tube with integral structures printed in Titanium.. bill was more than 1000 dollars for one tube, that was even without the 3D file preparation that was done out of courtesy by the facility. Orthfon prints their cartridge bodies this way, MC-Anna is the last example.

You likely meant melting (3D selective laser melting), instead of printing (sla).

It's really laser welding in a oxygen protected environment. The process welds titanium layer by layer, into a solid structure. app 15-20 layers pr mm. Something similar is done in UV cured materials/resins and also in thermoplastic powders, but items are not to be confused with real processed materials.

In post 8939 of the thread as a casual remark an inductive tube PSU of Andrejs is mentioned:
MPP

In a classical tubed power supply normally a choke is used, so I assume with ‘inductive’ is meant something else, maybe: phase consistent? Can someone please comment, or provide a link to contact Andrejs?

Real bipolars can be quite good.
