Device 6 is arranged on platform matrix 4, and the lower end of described platform matrix 4 is provided with shaped platform 3, and disk of material 2 is positioned at shaped platform 3
Underface, ray machine is then positioned at the position directly below of disk of material 2, and described force feedback sensor 6 can be examined when shaped platform 3 moves
Measure the change of adaptability to changes, therefore can be with the peel force between shaped platform described in Real-time Feedback 3 and disk of material 2 and stripping speed
Degree, the data collected according to force feedback sensor 6 further calculate, and the speed the most effectively risen platform is entered
Row controls in real time, it is ensured that peel off successfully, improves print quality.
Embodiment one:
As shown in Figures 2 and 3, the platform matrix 4 of this embodiment includes connection substrate 41 and three connectors, and these three connects
Part is respectively the first connector the 42, second connector 43 and the 3rd connector 44, and described first connector 42 and second connects
Part 43 all be connected substrate 41 and connect, described force feedback sensor 6 is fixed between the first connector 42 and the second connector 43,

On bar slide rail 5, the shaped platform 3 of this embodiment is arranged on the bottom surface of platform matrix 4.As it is shown on figure 3, the first of this embodiment connects
The bottom of fitting 42 is screwed connection with the described end face being connected substrate 41, and the bottom of described first connector 42 is to side
While be extended with boss 421, the bottom of described force feedback sensor 6 is fixed on described boss 421 upper end；Described second connector 43
Bottom connect by two screws are fixing with the described substrate 41 of being connected, the top of described second connector 43 is to away from two spiral shells
The side of silk is extended with flange 431, and the top of described force feedback sensor 6 is fixed on described flange 431 lower end；This embodiment
The top of force feedback sensor 6 is all connected with the first connector 42 and the second connector 43 by screw with bottom；Described
The side of three connectors 44 is screwed with another side of the second connector 43 and is connected, described 3rd connector 44 another
Side and described screw mandrel slide rail 5 slidable connection；The force feedback sensor 6 of this embodiment is Miniature Sensor, described force feedback
Sensor 6 is vertically fixed on the position of the geometric central axis line of described connection substrate 41, and this force feedback sensor 6 is a kind of by strain
Change is converted into a kind of equipment of the signal of telecommunication, and its important component part is resistance strain gage, in the design of force feedback sensor 6
Cheng Zhong, resistance strain gage is installed on the platform matrix 4 producing mechanical deformation, and its operation principle is for experience at platform matrix 4
To external force and when produce STRESS VARIATION, resistance strain gage itself also can occur stress deformation, thus cause its resistance to be sent out
Changing, the change of resistance directly results in the change of voltage.The resistance that the resistance of this foil gauge produces when strain occurs
Change the least, need to amplify voltage signal by follow-up amplifying circuit.
After being provided with force feedback sensor 6, effectively the process peeled off in the print procedure of each layer can be carried out reality
Time monitoring, can calculate according to the data that force feedback sensor 6 collects, thus effectively shaped platform 3 risen
Speed control in real time.Such as, printing the object that a certain layer cross-sectional area is the biggest, traditional printing device can not be appointed
What calculates directly is peeled off, and this often causes because separating the failure of too fast printing, and is provided with force feedback sensor 6
Printer can set a threshold values estimated according to the print area of monolayer, once monitors its peeling force in stripping process and is more than
During this threshold values, force feedback system can control motor and progressively run slowly, and attempts peeling off by less power, simultaneously threshold values according to
5% goes up, and by that analogy until this layer is completely exfoliated, thus effectively ensures the quality printed.Furthermore, force feedback sensor 6 is also
Another the biggest advantage is had to look for the end.What is called looks for the end, it is simply that DLP print ground floor before, shaped platform 3 need with
It is fully contacted bottom disk of material 2.Force feedback sensor 6 can gather Mechanical Data during shaped platform 3 declines, until
Reading occurs that this positive pressure value of normal pressure 20N(is exactly shaped platform 3 pressure when being fully contacted with disk of material 2), now slow down
Motor speed, until the value stabilization of force feedback sensor 6 monitoring is at 20N, then calculates and looks for end success.This process full automation, no
Need manpower intervention, and ensure that the concordance printed each time.
