The standard blocks are connected to each other and selected from the group consisting of a first standard block having a first elastic constant and a first height, a second standard block having a second elastic constant and the first height, a third standard block having the first elastic constant and a second height, and a fourth standard block having the second elastic constant and the second height. The standard blocks are manufactured by 3D printing and have identical lattices, and each standard block has a jointing structure. ## Claims ### Claim 1 A support element assembly, comprising at least two types of standard blocks, wherein the at least two types of standard blocks are detachably connected to each other and wherein the at least two types of standard blocks are selected from a group consisting of: a first standard block having a first elastic constant and a first height; a second standard block having a second elastic constant and the first height; a third standard block having the first elastic constant and a second height; and a fourth standard block having the second elastic constant and the second height, wherein the at least two types of standard blocks are manufactured by three-dimensional (3D) printing and have substantially identical lattices, and each of the at least two types of standard blocks has a jointing structure. ### Claim 2 (depends on 1) The support element assembly of claim 1, wherein the first elastic constant ranges from 3-15 N/mm. ### Claim 3 (depends on 1) The support element assembly of claim 1, wherein the second elastic constant ranges from 10-40 N/mm. ### Claim 4 (depends on 1) The support element assembly of claim 1, wherein a ratio of the first elastic constant to the second elastic constant ranges from 0.075-1.5. ### Claim 5 (depends on 1) The support element assembly of claim 1, wherein the first height equals an average distance between a top surface and a bottom surface of the first standard block or the second standard block, and the second height equals an average distance between a top surface and a bottom surface of the third standard block or the fourth standard block. ### Claim 6 (depends on 1) The support element assembly of claim 1, wherein an absolute value of a slope of an upper surface of the support element assembly is not greater than 0.75. ### Claim 7 (depends on 6) The support element assembly of claim 6, wherein the support element assembly is composed of a single layer of standard blocks in a height direction, the first height is less than the second height, and a difference between the first height and the second height is not greater than 75% of the second height. ### Claim 8 (depends on 1) The support element assembly of claim 1, wherein the lattices each have a lattice dimension of 8.5-10 mm. ### Claim 9 (depends on 1) The support element assembly of claim 1, wherein the lattices each have a lattice strut with a diameter of 0.9-1.0 mm. ### Claim 10 (depends on 1) The support element assembly of claim 1, wherein the jointing structure is one selected from a group consisting of a rail, a lock, a fastener, and a hook-and-loop fastener. ### Claim 11 (depends on 1) The support element assembly of claim 1, wherein the jointing structure comprises a groove defined on a first one of the at least two types of standard blocks and a slider defined on a second one of the at least two types of standard blocks, and a sidewall of the first one of the at least two types of standard blocks defining the groove surrounds more than 180 degrees of the slider. ### Claim 12 (depends on 1) The support element assembly of claim 1, wherein the jointing structure comprises a lock defined on a first one of the at least two types of standard blocks and a slot defined on a second one of the at least two types of standard blocks, the slot being configured to receive the lock such that a sidewall of the first one of the at least two types of standard blocks from which the lock protrudes abuts a sidewall of the second one of the at least two types of standard blocks into which the slot is defined. ### Claim 13 (depends on 1) The support element assembly of claim 1, wherein at least one of: the jointing structure comprises a groove defined on a first one of the at least two types of standard blocks and a slider defined on a second one of the at least two types of standard blocks, and a sidewall of the first one of the at least two types of standard blocks defining the groove surrounds more than 180 degrees of the slider, or the jointing structure comprises a lock defined on the first one of the at least two types of standard blocks and a slot defined on the second one of the at least two types of standard blocks, the slot being configured to receive the lock such that the sidewall of the first one of the at least two types of standard blocks from which the lock protrudes abuts a sidewall of the second one of the at least two types of standard blocks into which the slot is defined. ### Claim 14 (depends on 1) The support element assembly of claim 1, wherein the support element assembly consists of two of the first standard block, the second standard block, the third standard block, or the fourth standard block. ### Claim 15 (depends on 14) The support element assembly of claim 14, wherein each of the two of the first standard block, the second standard block, the third standard block, or the fourth standard block has a planar top surface. ### Claim 16 (depends on 1) The support element assembly of claim 1, wherein the support element assembly comprises at least three types of standard blocks, and the at least three types of standard blocks are selected from a group consist of the first standard block, the second

standard block, the second standard block, and the third standard block, and the second standard block is between the first standard block and the third standard block. ### Claim 18 (depends on 1) The support element assembly of claim 1, wherein the support element assembly comprises: a plurality of the first standard blocks, and the second standard block surrounded on at least three sides by the plurality of the first standard blocks. ### Claim 19 (depends on 18) The support element assembly of claim 18, wherein the support element assembly comprises: the fourth standard block, wherein at least one of the plurality of the first standard blocks is between the second standard block and the fourth standard block. ### Claim 20 (depends on 1) The support element assembly of claim 1, wherein each of the at least two types of standard blocks comprises extruded polyurethane.
