Industrial 3D printing.

The price depends on size, material volume, geometry, quantity, and finish. At Proto&Go! you upload the 3D model, specify your requirements, and receive a quote within 24 hours.

At Proto&Go! 3D printed parts are manufactured from 5 working days after order confirmation. The lead time depends on the design, quantity, and finish, and is confirmed in the quote. Shipping is added to the manufacturing lead time.

Yes. Proto&Go! manufactures via 3D printing from a single unit, without the need for molds or tooling. You can order a sample to verify the design before producing more parts.

It can be cost-effective because Multi Jet Fusion does not require manufacturing a mold. The cost depends on geometry, material, and finish. It is advisable to compare the quote for the run with other processes; quantity alone does not determine the most economical option.

Consider hollowing out solid areas, reducing material where it does not support loads, and requesting only the necessary finishes. Cavities must allow for powder removal. Savings are verified when quoting the design; lightening a part does not guarantee a proportional price reduction.

Multi Jet Fusion, or MJF, is an HP technology that manufactures parts layer by layer from polymer powder. It applies agents and heat to fuse the design areas. The part is then cooled and excess powder is removed.

They do not require added supports: unfused powder supports the part during printing. Once finished, this powder is removed. Cavities and channels must have access points to allow cleaning.

It is a technology that hardens liquid resin with a UV laser, layer by layer. The part comes out smooth and finely detailed, but it is printed on supports that are removed by hand and it gets a final cure. At Proto&Go! we offer it in white, black, and clear resin.

If the part is functional, MJF: it withstands loads, impacts and temperature. If it is aesthetic, SLA: it comes out smooth, takes paint and can be clear, but the resin deforms at 45–50 °C. The material selector settles it in two steps.

MJF 3D printing lets you manufacture complex geometries without a mold, in polyamides, polypropylene, or flexible TPA. CNC machining offers more metal and engineering plastic options and allows tighter fits. Choose based on the material, loads, tolerances, and finish the prototype needs.

3D printing allows you to manufacture and modify housings without creating a mold. Vacuum casting allows you to obtain polyurethane copies with various hardness levels, colors, and finishes. Compare both options based on quantity, material, and final appearance on the vacuum casting page.

Eight, in two technologies. With HP Multi Jet Fusion, for functional parts: PA12, PA11, PA12 GB, PP, and flexible TPA. With SLA, for appearance prototypes: white, black, and clear resin.

PA12 is suitable for rigid parts such as housings, supports, and assembly fixtures. TPA allows you to manufacture parts that compress or flex, such as bellows, protectors, and grips. The choice depends on the required rigidity, loads, and deformation.

PA12 is stiffer and more economical: it is the starting point. PA11 stretches up to 50% before breaking, versus 20% for PA12, so it handles impacts, clips, and hinges better. If the part has to flex, PA11.

It is PA12 with 40% glass beads. It is 40% stiffer, warps less, and at 1.82 MPa withstands 114 °C before deforming, versus 95 °C for PA12. It stretches only 10%: it is not suitable for clips or hinges. It works well for tooling, gauges, and brackets near heat.

90A indicates the nominal Shore A hardness of the TPA. The flexibility of the part also depends on the wall thickness and geometry: a thin wall flexes more than a block of the same material. To verify the feel and deformation, it is advisable to validate a sample.

MJF parts, yes, if the material and design meet the conditions of use: PA12 and PA11 in housings and fixtures, PP in contact with chemicals, TPA in flexible elements. SLA resin parts are for prototypes and models: they deform at 45–50 °C. Before manufacturing the run, check loads, temperature, wear, and chemicals.

PA12, PA11, and PA12 GB, in natural gray or black dyed; dyeing changes the color and keeps the texture. PP and TPA, natural gray only: PP cannot be dyed. In SLA, white and black resin can be painted (black is already dyed throughout), and clear resin is always delivered polished.

Yes, in clear SLA resin. It is always delivered with clear polish, included in the price: without it, the part remains translucent. Interior cavities that cannot be polished remain translucent. MJF materials are opaque.

In MJF, the build chamber measures 380 × 284 × 380 mm, with a recommended usable area of 356 × 280 × 356 mm. In SLA it depends on the resin: white up to 1,650 × 760 × 580 mm, clear 780 × 780 × 540 mm, and black 580 × 580 × 380 mm. See the build dimensions; larger parts are studied divided into sections.

The Proto&Go! reference for MJF is ±0.3 mm for dimensions up to 100 mm and ±0.3% above that. On a 200 mm dimension, that equals ±0.6 mm. In SLA it is ±0.2 mm or ±0.2%. If an area must fit with another part, specify the required tolerance so it can be reviewed before manufacturing.

For small PA12 walls, 1–1.5 mm is a starting point. Increase the thickness or add ribs if they are tall, long, or load-bearing. It is not a universal minimum: the design is reviewed based on geometry and application.

Yes, but it requires accessible exits to remove internal powder. For a simple PA12 housing, this guide references 2–3 mm walls and two opposite exits of Ø5 mm or more. A closed cavity retains powder and does not remain empty.

For simple holes in PA12, Ø2 mm is a recommended reference. Long or complex ducts may require a larger diameter or cleaning access. If the hole must fit a pin, specify the tolerance and consider subsequent drilling or reaming.

Yes, by modeling the full thread profile. Large threads resolve better than small ones; for M6 and smaller, consider inserts or subsequent threading. Specify metric and pitch and check the assembly with a sample before producing the run.

Yes. Inserts allow the use of metal threads in parts that are repeatedly screwed. Dimension the housing according to the insert datasheet, leave sufficient material around it, and ensure access for installation. Specify the reference and position when requesting the quote.

Yes, by incorporating it into the 3D model. As a reference, use letters of at least 2.5 mm height, strokes of 0.5 mm or more, and 1 mm relief or engraving. Small details must be checked against the final finish, as cleaning can soften their edges.

You can request them on the Proto&Go! platform, part of the i-mas group. Upload a file per part and specify material, finish, and quantity. An engineer reviews the design and you receive a quote within 24 hours. We ship parts to Spain and the rest of Europe.

Proto&Go! accepts STL and STEP for 3D printing, in addition to SLDPRT, X_T, X_B, IPT, CATPART, PRT, SAT, and 3DM. Upload a file per part. The STL format is supported for 3D printing; for other processes, a compatible CAD format is required.

To quote and manufacture, a 3D model is required. If you only have a drawing or a sketch, consult the i-mas engineering team to evaluate creating the model before requesting manufacturing.

The 3D file is the basis for reviewing the part. Attach a PDF if you need to specify specific tolerances, threads, inserts, or requirements not described by the model. Also specify material, quantity, and finish when requesting the quote.
