Q: Will I will be in touch with technical people ?
A: Definitely. This is one main advantages our customers enjoy: they are not talking to sales people only speaking english, but with people who understand technical and manufacturing issue, your market requirement and the commercial aspect.
Q: What about payment ?
A: You perform your payment online directly by booking your part with the booking process. You can pay via T/T , Paypal, Payoneer, or Skrill and it has to be done prior service.
Q: Do you own factory of prototyping
A: We are not owning 100% yet a factory of prototyping but we have direct interest in some of them via equity owning, in this way it ensure that we have control on some of them.
Q: How do you control my IP
A: All manufacturer which we work with are under NDA made from our chinese entity to their chinese entity. Those legal document are made in chinese and under the chinese law. We are using a chinese lawyer company to make sure those agreement are respected.
Q: What shoudl designer care of when desiging parts for prototype ?
A:There are many point a designer shoudl pay attention during designing parts:
Minimum and Maximum Size
As a rule, the typical minimum size for SLA prototyping is 0.2inches, while the maximum is 9.84inches. But there are variables to think about when planning size features. Those variables include wall thickness, featured function, interface, fittings with other parts as well.
Stair Stepping and Faceting
Faceting and stair stepping happens on each SLA model because they are built by overlapping layers. If the layers are further apart, you will notice heavier stepping on your models. On the contrary, if the layers are closer together, the stair stepping will be reduced and not be noticeable.
Another factor that affects the surface finishing of a SLA model is faceting, which is controlled by the output settings on your CAD software. If you export a coarse setting, the part will tend to have many triangles over the surface. However if you export a fine setting, the part will appear to have fine surface. The key is to find the balance that will take into consideration both features and part size to generate the best SLA prototyping model.
Hollow parts are decided by two factors. One, the limits of your partner producers’ capability. Two, your budget. Not all manufacturers can process highly accurate hollow or mesh parts. So before you get down to designing, you might as well take to your intended partner. Planning a hollow would be a good way to reduce the cost of a appearance model because cavity means lower material consumption, in turn lower material costs. So you have options on solid and hollow according to your fund and practical use of the prototype.
Points, Edges, Threads, Flat Surface and Cambered Surface
On occasion parts are designed with special small features like points, edges, threads and irregular surfaces. In theory, the final part should be in total coincidence with its digital model. But in practice, most SLA prototyping companies are not precise enough to build those special features because they tend to round off the small features into an integrated point or unit. That is especially true for thread design. We advise that you do not include threads in the design unless they are a course and on large diameters. It is also advisable to use taps or dies to create and thread features because those features will be much more functional than if they were designed into the CAD file.
Q: What are prototype used for ?
A prototype is also called a model or a mock-up. Some of you may ask what are prototypes used for or what’s the function of prototypes? So far, prototypes are generally used in the following five ways.
First, for market interest. During the market research phase, a mere photo or drawing is not enough to intrigue consumers. Having prototypes presented to users would be a perfect precise market interest barometer.
Second, for invest interest. Investors will also want to see a tactile product prior to investment. A great prototype shows that you are working with a reputable product design and manufacturing firm and gives investors more confidence in your market projections and manufacturing costs, thus enhancing your chances of receiving investment.
Third, to test design and function. It is commonplace that designs look great on paper but prototypes go awry. So we recommend you hire a team of rigorous, pro-challenge designers and engineers and equally importantly, an unit of first-class prototype makers. Those two powers will make sure you get the best confirmed design and prototype.
Fourth, to avoid manufacturing pitfall. The common pitfalls in manufacturing are costly design negligence or mistakes, manufacturing delays even processing difficulties. You anticipate the product will work out smoothly, but the fact is not. It’s paramount to run your prototype through market interest, product design, product safety and functionality tests before you decide to mass produce the product. Otherwise the cost can be deadly heavy.
Fifth, to test material pros and cons. Creating prototypes using different materials give you a better picture of different costs, user experience, performance index of your product.
Q: how many parts can you do with one silicone mold
A: The answer to this question is highly dependent on part geometry and choice of material, but typically you can expect a single rubber mold to yield about 25 parts.
Q: What tolerances can you hold?
A: Typical tolerances on our SLA models are about +/- 0.005″. For parts over 5″ we can hold around +/- 0.001″ to 0.0015″ per inch. Part geometry and build orientation can also have an effect on tolerances.
For prototype parts, general tolerance is +/-0.1mm. We can achieve +/-0.05mm or even higher tolerance if it is needed. For precision machining parts, CNC milling (+/-0.05mm), CNC turning (+/-0.02mm), grinding and EDM (+/-0.005mm)
Q: Which format file should I send to you for prototyping
A: Normally, rapid prototyping companies need 3D data format as: .igs, .stp, .stl, .x_t.
We prefer STP / STEP or IGS.
Q: What is advantages and disadvantages of Rapid Prototyping?
Significant advantages of rapid prototyping include reduction of project cost and risk.
Generally, one or more prototypes are developed in the process of development in a series of incremental and iterative steps. Every prototype that is manufactured is based on the previous designs’ performance and it is a corrective process through which the past design defects or problems are corrected. The product is readied for production when the prototype is refined as per requirements and meets all the design goals like manufacturability, robustness and functionality.
Q: If I have no CAD file of my item and still would like to perform a prototype, what should I do ?
A: If you have no CAD file but have a physical item, then the CAD file have to be reconstructed. You can use the service of one of our partner to perform this conversion of real item into CAD file and then come back to us for rapid prototyping with the CAD file for prototyping processing.
Q: Who are yours customers ?
A: We have customers fromall over the world and from different size. It goes from the small entrepreneur or hobbyist willing to make an enclosure for its PCB board to the multinational developping some electronic device for nuclear industry.
