  • Page 3: Introduction

    INTRODUCTION A8 FDM 3D printer can print CAD 3D printer model to real . A8 uses Acrylic to build its frame while it uses linear bearings , belts and threaded rods to build X , Y , Z axis .

  • Page 4: A. Security Considerations

    A. Security Considerations To avoid danger when using 3D printer , please pay attention to precautions below . Danger During Operation , the maximum temeprature of nozzle can be 260 ℃ while hotbed can be 100 ℃ . For your safety , during printing or cooling down , do not touch the nozzle , hotbed and models under printing .

    2.3 Layer height settings Layer height：0.1mm cost long time but have the best printing precision. 0.2mm cost half time compared to 0.1mm , but have general printing precision. 0.3 cost less time with not good precision. It defaults 0.2mm. Left： 0.1mm Right：...
  • Page 25 The Blue line is the leak filament Enable retraction Enable retraction to avoid filaments leakage when nozzles move in empty area Bottom/Top thickness: 1.2mm Under the same fill density When fill density is less than 20%, it’s easy for 0.6mm thickness to cause hollow on the top.
  • Page 26 Bottom/Top thickness setting Fill Density Setting Fill Density: If strength requirement is not so high , set 10% is ok. Please improve fill density when strength requirement gets higher. Printing time will go up as well. Printing Speed setting This is default speed. If other settings aren’t changed, it prints more accurately while the printing process takes more time.
  • Page 27 Original Model Support type: None Support type: Touching Support type: Everywhere Support type setting buildplate Attention: Normally we add support to complex model or model with vacant parts. It may have influence on the surface if you choose everywhere. You’d better circle around the model and try to avoid unnecessary support.
  • Page 28 None: no support Brim:Touch with the adge Support setting Raft: Totally touch with the bottom Attention: please choose None if the printing platform is ready and the high temperature adhesive tape is good. Please choose Brim when the model is small . Choosing Raft makes it difficult to seperate model from the platform...
  • Page 29 Attention: A8 use 1.75mm filament Attention: Flow is proportion of filament , we suggest to use 100 Increasing flow & decrease diameter has the similar effect. Model surface gets many bumps when flow is too big;model frame gets flimsy if flow is too small.

  • Page 33 Skirt is to avoid extruder unfilled before printing , and it appears only when platform attachment type is None. Normally “1” is ok . Change it to “0” when your model reaches the maximum size , or the printing size will be too big. Peripheral line quantity: 1 Peripheral line quantity: 1 Start distance: 3...
  • Page 34 1. To ensure the attachment of model to platform , fan won’t start at the beginning. 2-4. Fan speed min & max : If they are not equal , the soft ware will choose a suitable speed during them. 5. Condition to choose cool head lift : When it’s printing with the minimum speed but still cannot reach the minimum time , you need to choose cool head lift .

The biggest progress Cura has made is the kinds of support structure types , making it easier to seperate from the model.
  • Page 38 30° 45° 60° It’s difficult to seperate if the distance between support and the supported place is too close; The surface will be influenced if the distance is too far. Different angle will generate different support , you can try the examples we provide above which will have different effect.
  • Page 39 When choosing “Spiralize When choosing “Only follow the outer contour” : Z axis mesh surface” : The nozzle rises while X,Y axis moves , prints along the surface. and only a hollow bottom and a single layer of surface. Attention: The software defaults not open the option above , you’d better not turn it on .
