Rule of SIST 3D printer management

3D打印机使用管理办法(暂行)

In order to manage 3D printer effectively and provide good service to ShanghaiTech customers, we do the following rule:

为了高效的管理3D打印机,及更好的为客户服务,特制定本管理办法:

1.      3D printer operator should check and maintain printer regularly, and record the log.

3D 打印机操作人员需定期检查和维护设备，并做记录。

2.      If customers apply to print model, please follow below procedure:

客户申请打印3D模型，请按照下面的流程进行：

a)      Please learn about the function of the 3D printer via internet or consulting the operator first.

Dimension：https://www.aurora.com.cn/3d/Product/Details.aspx?id=30&sid=2&pid=5#title

Object：http://www.stratasys.com/3d-printers/objet260-connex3
请首先了解3D打印机的功能，可以通过网站或直接向操作员咨询。

Object：http://www.stratasys.com.cn/3d-printers/design-series/objet260-connex3

b)      Design your own model. You can use any software you like, but please output your model as STL format. The 3D printers can only recognize STL file.
设计你的模型。你可以使用任何你喜欢的软件进行设计，但是请最终输出STL格式的文件，3D打印机只能识别STL文件。

c)      Send the approved model by PI to operator, and send the requirement to the operator at the same time, including printer model, material, surface smoothness and so on.
将通过PI批准的.stl模型以及具体的打印要求发给3D打印机操作人员,打印要求包括：使用的打印机型号，材料的类型以及模型的表面光洁度等。

d)     Operator will check if the STL model is Ok to print.
操作人员对模型进行检查,确认是否可以正常打印。如不能打印，则告知用户重新设计。

e)      Operator will calculate the cost for printing.

如模型没问题，则由操作人员计算打印模型所需的花费，并反馈给用户。

f)       Customer confirms the cost and pay. Then operator feedbacks a pick-up time.

用户确认打印费用，并支付。操作人员会反馈取模型的时间。

g)      Customer pick up the model according to the time negotiated with the operator before.
用户按照之前和操作人员约定的时间取打印模型。

3.      Model cost is calculated by this way 模型的费用计算方法如下:

a)      Dimension Elite 3D printer/Dimension Elite 3D打印机

Build model dimension max: 203×203×305mm (8×8×12inch)
Layer thickness: 0.1778/0.2550mm
Settlement: by weight, layer thickness and grid numbers of pallet,
V: volume of build, P: price per volume, N: grid number of pallet
Cost of build will be calculated as follows:
1) 0.2550mm: (V×P +N×4) ×120%
2) 0.1778mm: (V×P +N×4)×130% (cost of time)
最大打印尺寸：203×203×305mm (8×8×12inch)
层厚选择: 0.1778mm或0.2550mm

结算方式: 耗材重量和托盘使用格数
V: 打印件体积, P: 单位体积的价格, N: 托盘使用格数
计算方式:

1) 当层厚选0.2550mm时: 总费用＝(V×P +N×4元／格) ×120%
2) 当层厚选0.1778mm时: 总费用＝(V×P +N×4元／格)×130%

b)      Object260 Connex 3 3D printer/Obeject260 Connex3 3D打印机

Build model dimension max: 255×252×200mm (10×9.9×7.9inch)
Layer thickness: 0.016mm
Settlement: by weight, and materials
W₁: weight of material 1, W₂: weight of material 2, W₃: weight of material 3, W₄: weight of material 4
P₁: price of material 1 per weight, P₂: price of material 2 per weight, P₃: price of material 3 per weight, P₄: price of material 4 per weight
Cost of build will be calculated as follows:
Total cost = (W₁× P₁+ W₂× P₂+ W₃× P₃+ W₄× P₄) × 130% (Operation fee is 30%)
最大打印尺寸：255×252×200mm (10×9.9×7.9inch)
层厚: 0.016mm
W₁: 材料1的重量, W₂: 材料2的重量, W₃: 材料3的重量, W₄: 材料4的重量
P₁: 材料1的单位重量价格, P₂: 材料2的单位重量价格, P₃: 材料3的单位重量价格, P₄: 材料4的单位重量价格….
计算方式: 总费用＝(W₁× P₁+ W₂× P₂+ W₃× P₃+ W₄× P₄) ×130%(30%设备运行费)

4.      ShanghaiTech SIST has the first priority to print model.

打印安排优先满足上海科技大学信息学院的使用需求。
