The Snapmaker Dual Extrusion 3D Printing Module will be available for pre-order soon! I have collected some questions from our group members about the upcoming product and would like to share the answers with you here. If this FAQ does not cover your questions, you can write your questions under this post or start a new post to discuss with other group members. I will keep updating this FAQ post for Snapmaker Dual Extrusion 3D Printing Module.
Without further ado, let’s check out the FAQs:
Q1: How will filament runout detection work? Will both nozzles stop if one runs out?
A: When you print a model only using one nozzle, the working nozzle will stop printing when the filament runout is detected on the working nozzle. The filament runout on the other nozzle won’t affect the working nozzle; When you print a model using two nozzles, like bicolor or dual-material printing, the Dual Extrusion Module will stop working when filament runout is detected on either nozzle.
Q2: Temperature wise, what would be the upper limit?
A: The Snapmaker Dual Extrusion 3D Printing Module‘s nozzle can reach 300℃.
Q3: Are the hot ends all metal?
A: The hot ends are not all-metal. In the inner structure of the hot end, the heating block and nozzle are all-metal structures. We use a PTFE tube connector inside the heat break, which can reduce the resistance during filament feeding and restrict the heat transfer to avoid filament jam in the heat sink.
Q4: Do you know if the Dual Extruder Module have any PTFE tubing connectors? If not then we will have the same problem as the single filament Module - the head is pooled (up) when the filament is being fed.
A: Yes, there are PTFE tube connectors. The PTFE tube in the Dual Extrusion 3D Printing Module is placed inside the heat break (heat throat), away from the heated block, the temperature of the PTEF tube is about 60℃ when the nozzle is heated to 300℃, which can prevent the aging of PTEF.
Q5: By the way, the filament runout sensor also detects filament jam/stuck?
A: The filament runout detection sensor can’t detect the filament jam/stuck.
Q6: Would be especially nice if the nozzles are quick change, and the e-steps and k-factor could also be saved as a setting for quick activation at the same time.
A: The nozzles are quick-swappable, you can replace them within 55s. The e-step has been calibrated on the production line, so you don’t have to calibrate it yourself. Currently, you can’t adjust the k-factor or the e-step directly on the screen or in Luban, but you can change them via the g-code.
Q8: Same hotend parts as the Artisan module or the 2.0? Nozzle specs?
A: Yes, the same hotend parts. The Snapmaker Dual Extrusion 3D Printing Module comes with 2 hotends (with the 0.4 mm nozzle). You can order the other types separately in our online store, we provide .2/.4/.6/.8 mm & hardened .4 mm nozzles.
Q9: Will the 2.0 have enough power to heat both nozzles sufficiently? Will the max extrusion temperature be less than the Artisian (if the 2.0 cannot handle the amperage required)?
A: Yes, the 2.0 can heat up both nozzles sufficiently. It only takes about 2.5 minutes to heat the nozzle to 300℃. As mentioned above, the max extrusion temperature is 300℃, the same as Artisan.
Q10: What changes to Luban will be made to allow choosing different filament types/colors for different parts of a model?
A: For models designed for bicolor or dual-material printing, you can directly assign different extruders (materials) to different parts.
Q11: I would expect a small sample pack with exciting examples in Luban to expand the users horizons. At least a small sample of (200-500g) PVA, CF-PETG, and something else special that only a multi-material user would think to use.
A: The Snapmaker Dual Extrusion 3D Printing Module (for Snapmaker 2.0) comes with breakaway support filament (500 g) and the sample project will be a dual-material printing model (PLA + Breakaway Support).
Q12: I hope there is some option to have the outer layers change color so that you can save on more expensive filament using it only for the outer layers.
A: Hi, Luban has a “Shell” option that allows the first & top layers and outer walls to change color.
Q13: I just want to be able to control flow in the Printer, please.
A: The “Flow control” function will be added to the screen for Snapmaker Dual Extrusion 3D Printing Module. This feature is planned for V1.15.0, which will be released before customers receive the module.
Q14: Is the price point currently known?
A: Yes. The MSRP is 599 USD, pre-order price is 399 USD (including free shipping via international air transport). If you purchase the Dual Extrusion Module during Sep 27 - 30, you can get it for 369 USD!
