Abstract
In the paper, it makes 3-D (three dimensional) printing rapid prototyping bitmap data compression research based on bytes has been conducted, in the 3-D printing rapid prototyping system, where the bitmap data format is adopted, and related data storage space is very large. It firstly analyzes the bitmap data characteristics in 3-D printing rapid prototyping system and the commonly methods used in nondestructive bitmap compression, and it designs the bitmap data compression coding method based on bytes. The compression method has the characteristics such as high compression ratio, fast speed of compression and decompression, less time consuming, etc. Therefore, it can meet the increasing demand of data compression in the 3-D printing rapid prototyping system.
Highlights
Concept of 3-D printing and rapid prototyping technology was proposed by scansE
M. and cima M J of the Massachusetts institute of technology (MIT) in 1992, 3-D printing is a kind of rapid prototyping technology based on material in drople form, spray forming, it is similar to the single layer ink-jet printing process, namely under the excitation of digital signal, it makes liquid material in the print head work forming droplets or flash droplets, which are formed by jet from the nozzle at a certain frequency and speed, and injected to the specified location, step by step through accumulation, the 3-D entity is formed [1,2,3]
This paper combines the needs of bitmap data characteristics and the forming process in the light curing three-dimensional rapid printing system, and designs a new bitmap data compression method based on byte which can be used in the light curing three dimensional printing systems [7,8,9]
Summary
Concept of 3-D printing and rapid prototyping technology was proposed by scansE. M. and cima M J of the Massachusetts institute of technology (MIT) in 1992, 3-D printing is a kind of rapid prototyping technology based on material in drople form, spray forming, it is similar to the single layer ink-jet printing process, namely under the excitation of digital signal, it makes liquid material in the print head work forming droplets or flash droplets, which are formed by jet from the nozzle at a certain frequency and speed, and injected to the specified location, step by step through accumulation, the 3-D entity is formed [1,2,3]. In order to facilitate the support bitmap, in the light curing 3-D printing system, the online real-time slicing and bitmap data generated level are not suitable, and adopting the offline data generation method, namely that through forming data processing software to generate and preserve the bitmap data of layer in slices type. Light curing forming process of 3-D printing rapid prototyping system is to print and pile up the layer one by one, and eventually form a three-dimensional entity, each layer of the bitmap data is not allowed to have any loss, or it will influence the forming precision or even influence forming process, in the light curing 3-D printing rapid prototyping system, the bitmap can only adopt lossless data compression technology. This paper combines the needs of bitmap data characteristics and the forming process in the light curing three-dimensional rapid printing system, and designs a new bitmap data compression method based on byte which can be used in the light curing three dimensional printing systems [7,8,9]
