Module collection is made with gypsum for step 1, including ten side lengths be 1 centimetre filling square, five side lengths be 2 centimetres
Square and two side lengths are filled as 5 centimetres of filling square.Wherein, four side lengths are 1 centimetre filling square, two
The end face center for the filling square that the filling square and a side length that side length is 2 centimetres are 5 centimetres is equipped with pit, in bottom surface
The heart keeps smooth, and other filling squares are then equipped with pit in end face center, is equipped with and groove position, shape in bottom center
The protrusion matched.
Certainly, module collection may be wooden or the materials such as polyethylene are made.The module of foundation is concentrated, and square is respectively filled
Quantity can be set as needed for more, as long as be able to satisfy actual use need.
Step 2 carries out print data building to 3D printing model by 3D printer.
Step 3, meet minimum module collection fill conditions under the premise of, calculating needs filling module collection in 3D printing model
The spatial information in each filling space, under the premise of each filling space retains the edge 1cm, according to the sky in each filling space
Between information calculate the volume of the largest square column that remaining filling space can place, and according to the size for filling square with
The mode of rounding up calculates the combination largest square column filling square value volume and range of product actually required, just according to filling
The calculating of cube value volume and range of product is actually filled space, and remaining space is determined as printing by 3D printer, completes 3D and beats
Print spatial position, size, structure and the information architecture for printing process.
In this example, as shown in Figure 1, meeting there are two the filling spaces that minimum filling requires, one empty for the filling of vertical shape
Between 1, one be horizontal filling space 2, calculate separately two filling space spatial informations, be subsequent layout filling square
Quantity, type and mode help is provided.Certainly, if not meeting the filling space of minimum filling module collection, 3D printing
Chance is constructed according to the print data of step 2 as a result, being directly entered step 4 completes subsequent 3D printing process.Retain 1cm3D printing

Intensity and toughness.Under the premise of retaining printing edge 3 1cm3D, is subtracted according to the spatial information in each filling space and accordingly stayed
Volume occupied by side obtains remaining filling spatial information, carries out largest square column according to remaining filling spatial information
Spatial simulation is placed, and the volume of largest square column that can be placed is obtained, in conjunction with the module collection being arranged in step 1, to gather
Perfect square formula determines type, quantity and the side of stacking of the actually required each filling square 4 of combination largest square column
Formula, then the body that filling square 4 actually occupies is calculated by actually required filling 4 type of square, quantity and stacking mode
Product subtracts practical occupancys volume just and can obtain removal by the spatial information in each filling space and is filled volume actual needs outside
3D printing volume, and then complete 3D printing spatial position, size, structure and print process information architecture.It is horizontal in this example
The volume that shape fills the largest square column that the simulation of space 2 is placed is 10.658 cubic centimetres, square side length and high score
Not Wei 2.2cm, can be used 1 only is that 2 centimetres of filling square is filled with dimpled, side length, remaining 0.2 li
Meter Bian Chang and Gao Ze are completed by 3D printing, and since pit is smaller, when 3D printing, issuable loading can be ignored；Vertically

Centimetre space is then completed by 3D printing.Certainly, if under the premise of retaining 1cm3D printing edge 3, residue filling spatial simulation is put
The volume for the largest square column set is not able to satisfy the filling requirement of minimum filling square, then equally no longer carries out module collection
Filling directly completes 3D printing process using the print data constructed in step 2 in step 4.
Step 4, according to building information, starting 3D printer printed.
When step 3 is unable to satisfy, the building information of this step is the print data information constructed in step 2, when step 3
When satisfaction filling requires, the building information of this step is 3D printing spatial position, size, structure and the information for printing process.
Step 5, after the structure printing in filling square filling space of unit is completed in 3D printing, 3D printer is temporary
Stop, external mechanical hand or manually the filling square is put into the filling space that the printing of corresponding this layer is completed, filling
The filling space either flush of square top surface and printing completion is filled, 3D printer is again started up, continues to complete subsequent 3D and beat
Print process.When subsequent filling square is superimposed, the protrusion clamping and being embedded in positioned at upper layer filling square bottom center is located at
Lower layer fills in the pit of square end face center, and so on.
Due to 3D printer using from bottom to top, by the way of successively section printing, it is first so when space is filled in printing
First the bottom of 3D printing product is printed and is completed, then successively printing upwards, gradually forms the peripheral structure in filling space, when filling out
When filling the height in space and being equal to the filling square height of a unit, 3D printer pause, by external mechanical hand or artificial
Corresponding filling square is embedded into filling space, the filling square of filling can be one or one layer, in this example, such as
Shown in Fig. 1, since horizontal filling space 2 needs filler height consistent with first that vertical shape fills space 1, so in 3D
When printer suspends for the first time, while it is empty to need for the filling square 4 of two different sizes to be respectively put into corresponding filling
Between in, be maintained in the same horizontal plane at the top of two filling squares 4 of filling, and with printing complete filling space top surface
It keeps concordant, just will not influence subsequent layer-by-layer section print procedure in this way.Finally, 3D printer is again started up, after continuing to complete
Continuous printing, filling process.The filling cube structure being superimposed in space 1 to keep vertical shape to fill is stablized, between upper and lower layer
Filling square between mutual clamping carried out by the cooperation of protrusion 5 and pit 6, protrusion 5 and pit 6 are semicircle, diameter
Smaller, clamping process will not influence contacting with each other for face and face between upper and lower filling square, meanwhile, vertical shape filling is empty
Between 1 and the shape in filling space that retains during 3D printing of horizontal filling space 2 with it is square to be placed into the filling of quantity
The shape of body matches, and has also further ensured that the stability of structure, enhances the structural strength of 3D printing product.
Step 6, until whole 3D printing processes are completed.
