3D打印机越来越便宜。有些甚至和英镑一样便宜;99/$135(101英雄),但在这样的成本削减水平下,必须有所付出,而且,一般来说,这是在所使用的零件中。所以当我在Gearbest for£118/$163交付,我想“这是另一台廉价、低质量的打印机吗?”;于是我去了谷歌,发现了一个由制造商组成的社区,他们把这台便宜的打印机做成了很棒的东西。所以让我们花一点时间,喝一杯咖啡,看看AANT A8 3D打印机的利弊。

Anet A8作为DIY工具包装在包装良好的盒子里,对里面的东西有很多保护,在盒子里,我们找到了组装工具包所需的一切。不,我是说真的,他们甚至提供了组装工具,齐平刀具特别可爱!3D打印机机箱由8mm厚的亚克力制成,并使用各种机器螺钉和螺母进行组装。组装大约需要半天时间,包装盒中的闪存驱动器/micro SD以PDF格式提供了组装打印机的完整指南。对于那些喜欢观看过程的人来说,YouTube上还有一个很棒的教程。花点时间进行装配,并始终确保在进行装配前理解该步骤。组装相当容易。当然,我们在构建过程中也犯了一些错误,但一点耐心都不能做到;无法解决。

组装好后,需要校准打印机。为此,请使用一张A4纸张并关闭打印机的步进电机,然后将挤出机移动到打印机的每个角落,并检查纸张是否可以在挤出机下自由滑动。应存在少量阻力,但纸张应以较小或无作用力移动。如果没有,则使用床边的螺钉点来改变床身高度。检查拐角后,将挤出机移到打印床的中心,并进行相同的测试。

准备好后,加载附带的灯丝并尝试micro SD卡上的一个测试文件。当然,第一份印刷品赢了;不要去计划,但它会告诉你如何调整打印机,这是一个可以调整的打印机。为了确保打印留在打印床上,打印床本身被加热到约60摄氏度(但可以更高),这对于3D打印机来说是一个不错的选择,因为便宜的打印机通常依靠胶水棒和胶带来帮助打印从床上提起。

调整和测试

如果你喜欢修修补补,那么每个访问ElectromMaker的人都喜欢修修补补,那么Anet A8是进行增强和黑客攻击的地方,但首先,我们需要学习基础知识。

Anet A8不仅仅是一款“即插即用”它的操作中有许多调整和警告。首先,需要手动调平和调整打印床(但有一个售后套件可用于自动调平打印床)。其次,x轴和y轴需要拧紧和调整,以确保打印质量(同样有许多社区对此进行了攻击)。在我们的测试中,y轴松动,在移动打印床时引起抖动,因此我们收紧了轨道,一切顺利。此外,打印床底部的蝶形螺母也容易松动。其中一个甚至被框架夹住,发出可怕的抖动/刺耳噪音,所以在打印前确保翼形螺母牢固。亚克力框架虽然坚固耐用,但可能会松动,需要少量维护。但社区有你的支持,你可以打印出额外的部分,以进一步加强框架。另一个“有趣”hack是一种降低Anet A8&hellip产生的噪音的方法;哦,是的,相当吵。

软件

Anet A8的控制器板是典型的ATMEL ATMEGA,它连接步进电机、挤出机等,与gcode一起使用,gcode是一种指示打印机在某一点执行操作的语言,与K40激光切割机等激光切割机使用相同的语言;和其他计算机控制的设备。

那么我们如何得到这个gcode呢?我们使用软件将.stl文件、3D可打印对象转换为gcode,最流行的选择是Cura(https://ultimaker.com/en/products/ultimaker-cura-software )

Once our machine settings are entered and saved as Anet A8, we can then import .stl files from places such as Thingiverse ( https://www.thingiverse.com/ ) or we can create our own objects using CAD applications such as Tinkercad ( https://www.tinkercad.com/#/ )

Anet A8 3D打印机评论

Let’s say that we create something in Tinkercad. Our workflow would be to create the object in Tinkercad, download it as an .stl file. Open the file in Cura. Edit the object and print settings, save the gcode to our microSD card, then insert that into the Anet A8. Mount the SD card, select the file and then print. Phew! Don’t worry this will become second nature after a few projects.

Safety

The Anet A8 3D printer has achieved some notoriety for catching fire, and this has been attributed to the included power supply unit getting rather warm, and that the mainboard is handling control of the motors, extruder and heated bed, that is quite a lot of amps for something so small.

So, to offset the risk of fire, we chose to repurpose an old PC ATX power supply using a benchtop power supply, which handily gives us 12V, 5V and 3.3V. This removes the included PSU from the fire safety risk, but the next modification was to purchase two MOSFETs (electronic switches designed to handle a higher current) one for the heated bed and another for the extruder.

These MOSFETs remove the load from the control board, and ensure we have a safe printing experience. So far we have installed the MOSFET for the heated bed, and it has worked remarkably well. Costing only £6 from eBay, this should be the first purchase that you make, well after the printer! The golden rule is to never leave a 3D printer unattended!

Community

The community that has formed around this printer is impressive. There are hacks and guides on how to get the most, including many enhancements that are available to download and print, most users print these enhancements first, to improve the Anet A8 experience. There are many videos to be watched and objects that can be printed, so take a look at the vast selection and decide what is important to you. For us, we printed a replacement extruder fan funnel as it made a horrible whistle noise when at 100% fan speed. This semi-circular fan shroud provides better air flow over the print bed.

So is the Anet A8 any good?

Anet A8 3D打印机评论

Quite simply yes. This printer produces decent quality prints after a little tweaking. If you have the time and knowledge, then this printer can be further tweaked to provide better quality prints. This is not a printer that you can just purchase and print, for that you will need an Ultimaker and also deep pockets as they retail for around £1000. The Anet A8, for £140 (current price, but this does fluctuate and has been as low as £95!) is a bargain. What you save in money you will need to invest in time, but it will help you learn more about 3D printers, how they work and how they can be fixed.

For makers and hackspaces, the Anet A8 is a challenging project and ongoing platform for manufacturing. You will get good prints from this printer, but not out of the box. Enjoy learning more about 3D printers

The Anet A8 is a great 3D printer and deserves your time. You will save plenty of money compared to other “consumer” printers, and you will learn how to maintain and use a 3D printer.
