Default My 3D printed ToneArm

After more than a year of work my 3D printed tonearm is finally playing.

The arm is based on the Schroeder tonearm and printed from PLA and PET-G using my home printer. I designed all the parts myself on SolidWorks.

Also, the arm has a working VTA and antiskating mechanisms.

Right now it sounds better than my Rega RB300 but still has a lot of room for improvement. Next step would be to improve the base and change the string and magnets.

A cool aspect of 3D printing is the ability the control the internal properties of the printed object. The printed object is not solid but actually has a polygon structure inside. When I print i can define the outer walls thickness and the density of the infill. For example - 3 mm thick walls and 30% infill. This is important because it allows me to control the final weight and mass of the arm and also kill unwanted resonance. With time, all this will be addressed.

Thank you for your time!

Tank out.

Wow! It's so cool! Do you mind sharing your design? I would love to try and print it.

You have done a beautiful job with that 3d system but from what I know plastic is going to add it's own dimension to the sound, just like the record if you don't clamp or deaden it somehow. You would be surprised at transmitted energy from some of your less compliant carts.

That's very nice! I can see the vta - looks like you turn the small knob to pull the string up. How is anti-skate controlled?

Is designing it a trial and error subjective process or are there quantitative measurements too?

Well done, looks amazing.

I started designing a wire frame one to be 3D printed. Have you seen some of the materials that Shapeways and others can use? Brass, stainless steel etc...
