You have chosen to misinterpret the objections.
The Lippes Loop lost FDA approval because it was proven over time to NOT BE EFFECTIVE and therefore better options exist.
No inert IUD (your...

Do we really need Forum Topics that are nothing more than pointers to "news" items on the same website?
Does this non-story with no real information deserve a discussion?

Deffinatly recomend replacing the acrylic print bed with the Aluminium one.
I bought mine from Stuffmaker at the same time as quite a few other items so frieght wasn't too bad.

For the heated bed...

Mine came with a 0.4mm nozzle and the warped acrylic print plate was quickly upgraded to the 3D Stuffmaker heavy duty Aluminium print plate.
I have mounted a Rep-rap bed heater and seperate...

Lippes loop does not require customisation and has lost FDA approval largely because it doesn't work as well as active IUDs.

No IUD requires any level of customisation, there is no such thing as a...

Mjolinor was more correct than you give credit, it is a matter of education rather than technology.
Effective and efficient contraceptives have been available for decades and still uncontrolled...

Do you have any idea how an IUD works? What makes you think they need to be customised?
They are a simple device requiring no customisation. One or two sizes fits all.
They rely on either embedded...

For a solid cylinder, you are right, I was thinking more of a tube than a solid cylinder. A tube or any other hollow shape could be of infinate diameter.
And it's still largely useless.

You are thinking in only terms of X/Y, this Bot can pivot around the object so the arm is always pointing at the centre of the object.

It could theoretically print an infinate diameter cylinder if it could drive AROUND the printed piece, so not moving in only X/Y but rotating around the centre of the cylinder.
That said it is still...

Why are you constantly promoting crack-pot ideas disguised as 3D Printing developments?
Last week it was the 3D Printer Farm robot that will single handedly solve world hunger, now it's the...

It's a plough, it's a discer, it's a seeder? Are you kidding me?
Have you seen a large farm-scale tractor plough a 40 acre field? Have you seen the speed at which broadacre seeders work?
Can you...

Jeff,
Brilliant, detailled honest review. You have done well to maintain the matter-of-fact tone of your posts as you work through the challenges of a new printer.
It seems to me however that you...

Alright, lets start fresh.
You are a little too evangelical about the future of 3D printing and your perception of the likely impact on traditional manufacturing.
You began your argument with...

What and double my CO2 footprint? I couldn't bear the thought.
BTW: My 3Dstuffmaker has been extremely reliable, it started life as a basic, no frills filament printer but I was able to build my own...

Oh, come on, "Reduce your carbon footprint dramatically, buy a 3D Printer" is NOT controversial? I would have thought that a fictional association of a product with significant carbon emission...

LOWER YOUR CARBON FOOTPRINT TREMENDOUSLY??
You are delusional, I have ordered more deliveries from overseas using dirty filthy production and delivery methods since buying my printer also delivered...

Slic3r and Cura are only good for print plate touching supports. They cannot effectively model in support within your model. They do it but it's not great.
The only solution is to model in your own...

In Slic3r's "Print Settings" tab, support material section there is a Raft checkbox and Raft layer height setting.

I'm no expert in CURA or Slic3r and I tend to use both. You will probably find one better than the other depending on the model being sliced.
CURA seems a little more intelligent regarding the order...

CalifDan,
Glad we could help with your twisted filament issue. I have encountered this issue with every roll I've used (dozens), some more than others. A good spool holder that feeds off close to...

That is some of the best concrete printing I've seen, BUT it appears to be just the skin of a building that will have reinforcement inserted and then filled with concrete to make a solid wall.
So...

This statement highlights the OP's lack of understanding of the entire 3D Printing Marketplace. " Why would someone buy a printer with printed upgrades" ? Seriously?
Learning your printer well...

3D? Really?
3D Printing is being mis-used as a marketing tactic in this instance.

I think you are developing an enormous amount of twist within the filament. This most often occurs in the last 25% of a tightly wound roll.
The filament wants to return to the shape it is holding on...
