Feeder de Robert sur UM2+

Recommended Posts

Salut,

En général la limite shore sur l'échelle A pour le système d'extrusion UM2 ( et le robert illustré ) tourne autour de 95, car cela dépend de paramètres comme les charges ou la composition chimique.

Au dessous de cette valeur tu devras te diriger vers d'autres systèmes comme :

- Si tu es baroudeuse mais pas trop ( + bowden tube diamètre interne 2.90-3.00 aide beaucoup) :

Tu pourras extruder correctement mais la gestion des rétractions reste toujours une affaire délicate.

- Si tu es une aventurière :

Système performant en direct pour shore pas évidents.

@darkdvd et @amedee et @neotko seront là pour te guider en cas de galère.

Je confirme toujours vérifier le shore (dureté du filament) , je n'ai pas trop d’expérience dans l'impression des flexibles mais j'imprime de temps en temps du Poliflex (polymaker)

voici les principaux réglages que j'utilise.

Vitesse d’impression basse 30mm/s

Température d’extrusion 215°

Plateau 70° (le filament adhère parfaitement)

Flow 110/115%

Ventilation 30%

Ne pas mettre la bobine sur le support, il faut la poser à côté de l’imprimante en déroulant un peu de fil.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
