ok3d have trained 3d printing company all over the world , the printing for ok3d various products in the printing business. We tried some new materials - high definition PP sheet, print the effect is almost no difference with PET. In recent years, there are a number of lenticular lens factory find someone to carve abrasive production PET lenticular lens, but still less than cmyk3d, mainly focusing on degree, printed image fuzzy, pattern of sharp enough.

Do three-dimensional product good or bad depends largely on the quality of the lenticular lens material, design techniques and numerical calculation is secondary. Early September just printed a few figure to a customers, the customer is a furniture manufacturer, three-dimensional picture is attached, furniture raise furniture selling point, is not to stick the three-dimensional paintings to sell. We are using 0.48 mm PP printing, effect is good, 3d effect is much weaker than PET0.6, but the resolution is better. PP material there is factory in zhejiang in the most thin 0.38mm stereograph, pattern is fuzzy, almost no stereo feeling,must scrapped.

A lot of people complain that,can't make good 3d quality of finished product, it's no wonder. Domestic lenticular is no national standard, the quality are not qualified. so-called manufacturer，some also don't understand specific focus depth and imaging parameters ；some won't say points too clear to customers, otherwise, who buy lenticular lens？

There are a lot of people ask us some specific technical details, this related to an enterprise's core interests, I'm sorry we can't say too clear, because the technology is developed for many years, we took a lot of energy and money, waste a lot of material to research a little and can't share for free , please understand.some 3d workers visit to other individual colleague company,they are rejected to enter into the door of design studio

, also for technology protection purposes.

Depth understanding & using ability for lenticular lens material is measure a three-dimensional main indicators of the technical level of the company. PP, PET, PS is the most commonly used three kinds of material, PVC and PMMA with relatively less, PVC actual amount is very big, but all of them are small trademarks, cup pad, mouse pad, do ordinary stereo picture. Not to use it PP on the stereoscopic printing amount is large, quality is generally can't keep up with a PET, but because the price cheap, in a lot of small specifications of the design on the market demand is very exuberant, foreign PP order many in the domestic printing, can explain this fact. We long time 3d99 is working with factory to develop a new type of PP, around 0.50 thick,if only see the 3d effect and don't touch, ordinary people can't see it is PP or PET. That is to say, a good PP PET imaging effect of worse than some.

From the perspective of materials science, PET is the most suitable for stereo, a lot of membrane material is PET material, but the PET has the difference on the quality grade, good good raw material is bright and clean, high flatness, focus, field of view Angle error is small. We are doing 3d design, want to consider what material to do. If is ordinary PP, because the refractive index, reflectivity, and imaging the limitation of actual depth of field, some 3d design detail is not necessary to all out, focus on a few 3d points. If it is a good PET, we can to get all of the details are done, can achieve very good artistic effect.

As for the common custom built big picture, only the PS material is a kind of choice. PMMA is too expensive, and domestic manufacturers, it won't. PS domestic there are a lot of new lenticular lens, 15 lines, 18 lines, 25 lines,32 lines ,42 lines,50 lines, etc. Do more to consider which one to use when painting lenticular lens, the effect is completely different. PS quality worse, we often see article lenticular lens when testing the lenticular lens is not straight, is tilted, black lenticular lens have thick have thin, even make it finished products, big arc images, this is all on the production process. So do is constantly struggling with lenticular lens three-dimensional painting process.

lenticular lens imaging principle is simple, the ordinary high school physics can calculates the numerical convex lens, but each lenticular lens arc is placed in the lens is not the integer, aberration calculation is very complicated, specialized higher optical formula. Ordinary stereo people don't need to understand so much, try each lenticular lens the actual depth of focus, with the depth of field in the software to design the depth conversion is good.

There are a lot of people buy pirated sequence diagrams, or copy others' sequence diagrams, want to use directly, but the effect is very poor. This is because the author is designed aiming at a kind of lenticular lens, and fixed dimensions, to use another lenticular lens. This figure is not universal, even change some lens, may also, if the size again, then no more.
