RP wax model
RP means “rapid prototyping”. Rapid prototyping is the best method of creating accurate a high resolution rp wax model directly from 3D cad data. We will create the cad file for you based on your simple sketch with basic measurements or even a fully detailed mechanical drawing. By using RP technology for making a rp wax model jewelry, toys and other highly detailed rp wax models will have fast, precise and cost effective rp wax models made. The models can be used for quickly making design changes and approvals or the rp models can go directly into the casting process.
Whether you will supply us with a fully detailed design or a simple sketch we will bring it into full 3-D life for you or your customer.
There are three main rapid prototype rp machines available suitable for jewelry, toy, medical and other applications requiring high rapid prototype model detail. We have made direct rapid prototype rp machine comparison using the identical cad file and has the following conclusion:
3D Systems makes a machine which is an attractively cased rapid prototype (rp) machine, simple to set up and use. The 3D System machine delivers very good quality and has excellent build speed. However the system has two major problems, the machine dependability is moderate and not all resin models will directly cast. Then a liquid mold must be made of each model. Not only does the mold process take a full day to cure but you loose a generation of quality. You still must cut the mold open and make a wax copy.
The Envision Perfactory rp machine uses an upgradeable dlp platform that is small, sleek and quite. The rapid prototype model quality is also very good. The perfactory resin models must have supports and rapid prototype rp model areas without perfect support structures are subject to warping and distortion. After the model is complete it must be cured and all the supports need to be removed.As with the above technology a liquid mold can be made. The mold process is time consuming and defeats the benefits of the machine growing fast models.
Solidscape makes the s350, s370, s390, s300, T76+, pro and max2 rapid prototype (rp) model machines. The build times are much slower than the above rp machines and the models are more fragile. But the Solidscape machines delivers the best rapid prototype model detail and surface finish. Most importantly the Solidscape series of machines build wax models that directly cast. There is no need for supports or model curing, which is great. The rp wax models are of the highest detail level. There is no need for a mold prior to casting. If you are like me I want to take a job and deliver the finished product.
The Solidscape series of rp wax machines are best we have used.
Adjustable Z-axis build layer: from 0.0005 inches (0.013 mm) to 0.0030 inches (0.076 mm)
Achievable accuracy: ± 0.001 inches (0.025 mm) per inch across the X, Y and Z dimensions
Surface finish: 32-63 micro-inches (RMS)
Minimum Feature Size: 0.010 inches (0.254 mm)
Calibrated Configurations for 0.0005, 0.0010, 0.0015, 0.0020, and 0.0030 inches build layer thickness
Maximum build envelope: 12 x 6 x 8.5 inches (30.48 x 15.24 x 21.59 cm)
Uses a non-toxic thermoplastic build material featuring excellent casting qualities (fast melt out, no ash or residue, negligible thermal expansion); highly suitable for direct investment casting and works with a variety of mold-making processes.
It is the most accurate, highest resolution rp machine currently available which can be within +/-0.05mm.
Ideal for parts with very fine feature such as jewelry, toys, medical implements, eyewear, etc.
Super fine layer thickness (0.013mm) is achievable.
