I posted another reply regarding thin wall features from an SLA machine.  If I had a jug, or a blow molded part, what is the thinnest wall I could have in order for Metro Rapid Prototyping to produce it?  Will the wall thickness be uniform throughout the part?  If not, how much will it vary?  I assume that it might not be possible to produce a urethane casting of a blow molded prototype...right?  If someone could shed some light on this, I would really appreciate it... Thanks

We commonly produce SL models of blow molded parts. The wall would be unifor with the exception of the steps created from the layering of the process. The biggest concern would be the strength of the SL model.  We could build the SL with walls as thin as .010 However it would be very fragile. I doubt any wall you needed would be that thin? You are right about the urethane parts.  We can not cast a prototype blow molded part. We could build two pieces, cast them seperately and then bond the castings together.

Malibu, thanks for the feedback.  I am looking for a way to produce roughly 10 blow molded prototypes before production for marketing and testing purposes.  10 Stereolithography models are going to be rather costly.  The part I have is not any sort of jug but rather a curved, convoluted tube which we are going to try to blow mold in production.  This parts is similar to the blow molded prototype example on your website. That part looks like a urethane casting.  What was the steps to produce that prototype? I am somewhat new to the plastics industry.  Do you have any suggestions on a production process that is cost effective for say an EAU of 50,000? Thanks in advance..

想要去神奇且独具魅力的国际旅游城市张家界自助游的游客，来张家界旅游需要注意什么呢，我想您首先应该注意的就是张家界地属湖南西部，是一个多民族地区，主要以土家族、苗族为主，请您保持良好心态，并尊重当地少数民族习惯，做到“入乡随俗”，这个是比较重要的。另外您还要注意以下几点：1，防止拉客：注意不要轻信别人是什么什么旅行社的导游，要是您跟团了，那就提前联系好旅行社，要是您是自助游，建议您找个自助游导游吧，张家界景区线路太复杂了，想看好点的景又不走冤枉路，就是要找个导游的，但是尽量在来张家界之前就在悠游张家界旅游网上找个口碑比较好的导游。2，乘车注意：很多的士说到哪里多少钱，贵是贵点，但是别相信10快就能送您40里路去景区的瞎话。乘公交要小心扒手，注意财产安全。3，湖南(湘西)地区为山区，道路交通多山道且大弯急，请您准备张家界旅游必要的药品(乘晕宁、抗生素等药物)。4，张家界景区多为山，体力消耗较大，请您根据自身体力选择爬山或自费乘坐缆车。游览中注意安全，登山应穿布鞋、橡胶鞋及旅游鞋，切忌穿皮鞋、高跟鞋和拖鞋。山高路陡，要做到“走路不看景，看景不看路，停步观景”。
