What kind of prototype are suitable for SLA prototype processing method to make? Prototype with high dimensional accuracy requirements (such as mobile phone, digital camera) Need prototypes more than three directions of processing
mobile phone prototype digital camera prototype more than three directions
Under what circumstances is not suitable for adopting SLA prototype processing
method to make?
The prototype need to resist high temperature The prototype need to resist impact
What data you need to provide to us when adopt SLA prototyping processing
method to make prototype?
First, you need to provide us 3D picture with entity diagram. All the 3D picture cannot
convert to STL form are not entity diagram.
Second, change the 3D picture to the picture of the suffix STL(such as “name.stl”)
Pay attention:Should change the chord height and angle control of the export STL dialog
deviation control options to 0.0000 during conversion, and then click apply options, the
system will accept the best parameters automatically. At last,click OK.

adjust parameter after exported STL format 3D picture.

Technical specifications of SLA prototyping
SLA prototyping processing principle
SLA is the abbreviation of stereolithography. In popular, that is programming the processing
according the shape of the prototype, and then guide the laser along the procedure specified
path to scan the photosensitive resin layer by layer .The photosensitive resin are solidified
into the solid irradiated by laser, then can process the prototype same as 3D picture. The
best characteristic is that there is no limit for the shape and structure of the prototype which
need to be processed, even cannot out of the mold products also can be processed out.

Processing case study
The structure of the above SLA1 and SLA2 are both fit for adopting SLA processing
to make, whereas, it cannot be processed if adopt CNC prototype process method to make.
Only can be finished by adopting split process. So the process accuracy will be greatly
reduced. If adopt SLS prototype, the cost will much higher than SLA
. Shown as the below picture:
