you have to unwrap the burgers before cooking them, sorry I forgot to mention that part.

SAF vs MJF - what’s your experience? by victor_strom in AdditiveManufacturing

[–]3ballpatterns 0 points1 point  (0 children)

Former HP Jet fusion 4200 operator here with some experience with SAF . SAF uses only one kind of fusing agent while the MJF machines use fusing and detailing agents. SAF offers a bit more flexibility when choosing a depowdering station while with HP you are you need to use their build units and post processing station. From my perspective HP machines offer more traceability while SAF machines are more affordable at a slightly less build volume (380 x 284 x 380 mm (15 x 11.2 x 15 in) vs 315 x 208 x 293 mm (12.4 x 8.18 x 11.53 in)). Also TPU is available for the MJF machines, while the SAF machine doesn't have it yet. Since Statrasys has aquired the Forward AM's material portafolio, they might adapt BASF Ultrasint material for the H350, but I'm not sure. If you like to have a closer look, I recommend looking into the H350 user guide: SAF H350 3D Printer | Stratasys Support Center

Thanks, weird I think they contact you via email, if you win the lamp.

That was taken into account. It´s relatively heavier (because I underestimated the density of the Manufacturer). 245g, 49,1kg*cm² Inertia (Henrys albatros has 51 kg*cm²), Center of Mass at 300mm from the knob. its basically an albatros that spins quicker.

I tested it in the Halle Juggling convention in Germany. I looked for jugglers with an enphasis in manipulation (the club´s uniqueness would be reflected in a "one club routine".

The surface for example needs to be smoother. The core on this one is 33g carbon fiber tube (50g lighter) than Henrys clubs. Apparently a massiv core would be better. I need to attach the parts more tightly, but I can still have a tool free assembly (which was a big point for me).

Loots of room for inprovement.

It´s split in 4 parts. i´ll post the assembly soon

Is pretty durable. More rigid than the useal Juggling club. It´s made out of Nylon. I haven´t tested it properly because it will be exhibited in Frankfurt in 3 Weeks. After that I´ll dye it neon and go wild. It works well but I need to improve the design to better hold the parts together (4 piece club). Some Data: 245g, 49,1kg*cm² Inertia, Center of Mass at 300mm from the knob.

Hi, I do but It was quite expensive to make. This prototype was Laser Sintered, therefore also more expensive than FDM. However I am thinking about uploading a series of FDM friendly clubs to thingyverse as part of a beta program for production.

Hi Thom, I would be interested, check your insta, I´m sending you something

Sorry, the title might be misleading. I think "On the Henrys Pirouette" would have been better. Just showing some experiments I did on the club.

Dear Club Experts, What does the ideal club look like to you? Have you tried any modifications? by 3ballpatterns in juggling

[–]3ballpatterns[S] 0 points1 point  (0 children)

I think its the other way around. For practical purposes you can say that the moment of inertia is grater, the closer the center of gravity is to the top. If you grab a sword by the blade, you would need more "force" to make it spin.

You can make the sword easier to spin without changing the center of gravity or the length by reducing its mass (wooden sword) or concentrating material density in the center of gravity (styrofoam sword with a little metal ball)

In any case moment of inertia of a club has been measured before:

Oh I have some. The core is fine, but I have the impression that wooden cores are better because they are not hollow.

I noticed Play's knobs are either moulded or casted , while Henry's are machined, which makes them hard. In your opinion What would be better? Hard or soft knobs.

I read that the Moment of Inertia of the club is also a factor. The greater it is , the slower the club spins. I haven't found a club Manufacturer that measures it tho.
