  1. 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.
  2. 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
  3. Hi everyone, any news or results about your prints with Ultrafuse 316L?
  4. 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.
  5. 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 so
  6. To be honest, i've never thought about the retraction speed and so on. I'll definitely check it out
  7. 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.
  8. 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.
  9. 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.
  10. 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
  11. 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.
  12. 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?
  13. ciao Luca, proverei a variare temperatura e % infill, tendenzialmente riducendo entrambi
  14. 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.
