[first layer extruder support]

Hi geert_2, 

 

thanks for your kind answer. Now i'll try to answer your question. 

The metal parts can reach density values near the base material. Just as an example, 7,7 g/cm^3 compared to 8. 

The green parts requires debinding and sintering processes, that we outsourced to a proper company. 

Unfortunately, the shrinkages are not always constant and they are definitely influenced by process parameters. Just to give an idea, 16/17% in X and Y axis; around 20% in Z axis. 

I attached an image of green and metal part. 

[first layer extruder support]

Hi everyone, 

 

i'm trying to use Ultrafuse 316L BASF filaments with Ultimaker support filament (i.e breakaway). Is there any chance i can print the entire first layer with breakaway filament?

Basically, i would that my component does not touch the built plate, but only the support material. 

 

I hope i explain my problem correctly.

 

Thank you, 

Mattia

Hi everyone, 

 

any news or results about your prints with Ultrafuse 316L?

 

 

[Top surface finishing]

I will try to reduce ironing insert and i hope i can fix this problem. 

 

I will send green parts back to BASF, more specific IGO3D (https://www.igo3d.com/debind-sinter-service-ticket). It costs about 50 euro per kilo, it's not expensive at all. 

[Top surface finishing]

Hi everyone,

 

I start to print with Ultrafuse 316L filament (BASF) and I have some problem with top surface finish. 

In the attached file ( sample_1), I disable Ironing option and there is no filament outside the surface's geometry. 

In the attached files (sample_2.1, sample_2.2, sample_2.3), I enable ironing option and there are pieces of material outside surface's geometry, like the nozzle dragged the material during the travel. 

I'd like to print with ironing because this option can ensure a good top surface finish. 

 

Can anyone give me any advice and solve this problem?

 

Thanks in advance!!

Another idea: Was this failed print, a print with a lot of retractions? Because when you have too much retractions this could also cause the grind in the filament. 

To be honest, i've never thought about the retraction speed and so on. I'll definitely check it out

[broken filaments]

I kept both cores and feeders clean. 

Generally i use the recommended print settings for all the filaments that i extruded. 

 

Now i will try to put back to 1/2 the tension of the spring. I don't understand what i need to do with PVA filament in terms of tension of spring in the feeder.

In the attached file you can see the current position of the spring in the feeder. 

I try to print and i can still notice a lack of filament's portion (not so bad as the filament in the image above). 

 

I do not use any polybox and i clean the core frequently. 

 

[broken filaments]

Hi everyone, 

 

I have a problem with filaments that broke in the feeders. In the attached file you can see different filaments (pla and pva) with this kind of problem. 

Do you have any advice about it? I try to loosen the screw, connected to the spring (in the feeder's box, back of the Ultimaker S5), but I got poor results. 

 

[support]

Hi everyone, 

 

I'm wondering if anyone can help me in this topic. Sometimes when I open a stl file, a support cylinder appears on the table built plate. Is there any chance i can delete this cylinder, that do no exist in the stl file?

In the attached file, the figure, that i want to delete, is in the top corner. 

Thanks

How much time took for the post processing including transit time? How about the cost? You think it is suitable for batches of 500 pieces? 

My interest in this filament is to use for industrial production but in smaller batches where injection and stamping does not fit in the ROI.

 

 

My feeder on that prusa is a e3D Titan Extruder Original. Even if the gear wears out it is pretty easy to replace it.

The cost is about 40/50 euro/chilo. I don't now anything about the transit time. I think BASF hasn't any problem in term of quantity to post-process.

 Have you tried already? Which core are you using and how you plan to do the post processing?

no, the filament is in transit. the core is CC 0.6 and i will send the green parts back to BASF for post processing. Did you try to extrude this material?

ciao Luca, 

proverei a variare temperatura e % infill, tendenzialmente riducendo entrambi

Hi everyone, 

 

I just bought an Ultrafuse BASF 316 LX filament and i'm going to use it with an Ultimaker S5. I'm wondering if anyone can give me any tip and tricks (temperature, shell, infill, quality, velocity, sample part to create) in order to properly create a perfect green part with this new material. 

 

Thanks in advice.
