    • Alors perso je n'ai jamais essayé, mais d'autres l'ont fait, et m'ont dit que ça ne marchait pas...  
    • Food and Drug Administration (FDA, « Agence américaine des produits alimentaires et médicamenteux » qui gère aussi les  matières utilisées en usage intra ou extra corporel (aciers , plastiques, composites , polymères) a usage chirurgical ou péri- chirurgical. Tous les matériaux que j'utilise pour fabriquer les Dispositif Médicaux doivent, au moins, avoir cette agrégation. C'est le cas de certains PLA,  de l'Amphora, ou le "Purement" (Pure Filament) qui a des propriété anti-microbiennes.     Pour réussir a imprimer certains de ces machins il faut des réglages spécifiques. Le "Purement" entre autre , demande un nivelage et une température spécifique sinon c'est décollement a coup sur. L'um3 fonctionne parfaitement avec les matériaux dédiées, mais le nivelage auto pour le "purement" est une cata. De mème je bouffe des membranes en silicone et des buses a n'en plus finir (vive 3Dsolex !!!) et les membranes je vais les dégager aussi pour les remplacer par une autre en  polymère HT a mémoire de forme de ma composition.   IDEX : Indépendant EXTrudder C'est le cas de la SIGMA qui a deux extrudeurs indépendants sur un même axe Ou de la STACKER S4 qui a quatre extrudeurs sur le même axe.   L'avantage de ces machines est que les extrudeurs inutilisés vont dans une zone de stockage, avec un bac pour chaque extrudeur destiné a recevoir les suintements. A la sortie de chaque bacs l'extrudeur passe au dessus d'une lame plastique qui vient lécher la buse pour l'essuyer  (que j'ai remplacé par une brosse métallique).   C'est plus clair comme ça je pense
    • Hi, @smartavionics,   I tried your suggestions, but still the same problem.  Cura 4.0 was just released and I gave it a try, but also the same problem.    I went back to "legacy" Cura and it's working -- no problems with small circular features. I'll continue to experiment with the settings in Cura 4.0 to try to find the problem.  Meanwhile, I'll keep slicing with legacy Cura or Slic3r.    I'm also considering Simplify3D...   Anyway, thanks for the attention. If you have any other ideas, please, let me know.   Best regards, Spencer    
    • Hi 3D-Ya,   I know this question is about what is error 13 reported from Cura. After some lurking around, I found this to be an old issue with Cura. The Error 13 seems to mean; Access denied.   As there is a hi number of Cura versions, it will helps a lot if we new the version you are using and how this happen.   What do you do when this error occur?   Thanks   Torgeir
    • Thanks to all here.  Very informative post.  I do get that the best tolerances can be built for in CAD (and I usually do).  Unfortunately, I was having to print a complex part that someone else designed.  All I had was an STL, but the print was part of a bigger installation where I needed better accuracy than I was getting with the default profile.  The horizon expansion adjustment (to -0.03) allowed me to get the expected tolerances without any other changes.  And this was printing with PETG (Polymaker Lite).
