This makes it the top choice for engineers, Designer, and creators who need exact precision. But finding the right online resin printing service can be tricky. With dozens of companies all claiming to offer the best quality and speed, picking the right one for your project can feel like guessing.
That’s where we help. We’ve looked past the marketing claims to give you a clear, fact-based comparison of the best companies in the business. We ordered the same test part from each service and judged them on what really matters: how easy they are to use, print quality, how fast they work, and overall value. This guide will help you confidently pick the perfect partner for your needs, whether you’re making a detailed miniature or a working engineering prototype. We’ll review Craftcloud, PCBWay, JLCPCB, Formbahnen, and Xometry.
What Is Resin Printing?
To make the best choice, it helps to understand how the technology works. Resin printing, officially called vat photopolymerization, builds objects layer by layer from liquid plastic resin. A light source hardens specific areas of the resin against a build plate, which slowly lifts the model out of the liquid tank. The result is a completely solid object with amazing detail.
How Resin Printing Works
While the basic idea is the same, there are three main ways to harden the resin. The technology a service uses affects speed, kosten, and how detailed the final print will be.
- SLA (Stereolithikromographie): The original method. It uses a precise laser to trace each layer’s pattern onto the resin. This gives outstanding accuracy but can be slower for large or solid parts.
- DLP (Digitale Lichtverarbeitung): This technology uses a digital light projector to flash an entire layer’s image at once. It’s much faster than SLA for full layers, making it great for production.
- MSLA (Masked Stereolithography): The most common technology today. It uses a powerful UV LED array that shines through an LCD screen, which acts as a mask to create the layer’s pattern. MSLA offers an excellent balance of high speed, great detail, and lower operating costs.
Key Service Benefits
Why use a resin printing service instead of buying your own machine? For professionals and serious hobbyists, the benefits often outweigh the cost and learning curve of owning equipment.
- Amazing Detail and Smooth Surfaces: Services use professional machines set up for incredibly fine detail – so klein wie 25-50 Mikrometer. This creates parts with almost invisible layer lines, perfect for display models, jewelry masters, and miniatures.
- Hohe Genauigkeit: For engineers creating parts that need to fit together perfectly or precise mechanical components, the exact measurements of professionally printed resin parts are critical. Services guarantee a level of precision that can be hard to achieve on home printers.
- Special Materials: Getting access to many different materials is a huge advantage. You can order parts in tough, engineering-grade resins, flexible resins, castable wax for jewelry, or even safe dental resins without needing to buy and store them yourself.
- No Mess: Owning a resin printer involves a messy process. You have to handle toxic chemicals, manage fumes with proper ventilation, and do multiple cleaning and curing steps. A service handles all of this for you, delivering a finished part ready to use.

Price vs. Precision Analysis
Choosing a service isn’t just about finding the lowest price. It’s about finding the best value for your specific project. Overpaying for precision you don’t need is wasteful, but under-investing in quality for a critical part can be even more costly.
What Affects Print Cost?
Several factors contribute to the final price of a resin-printed part. Understanding them helps you optimize your design for cost-effectiveness.
- Part Volume & Bounding Box: This is the primary cost driver. The more resin your part uses (Volumen) and the more space it takes up in the printer (bounding box), the more it will cost.
- Harztyp: Standard resins are the most affordable, with prices often ranging from $0.50 Zu $2.00 für cm³. Specialized materials like tough, castable, or high-temperature resins can be significantly more expensive due to their advanced properties.
- Auflösung & Schichthöhe: While higher resolution (Z.B., 25 microns vs. 50 Mikrometer) doesn’t always directly increase the price on instant quoters, it can increase print time, which may be factored into the cost by some services.
- Nachbearbeitung: The labor involved in removing supports, Waschen, and curing the part is built into the service’s price. Complex parts with intricate supports require more manual labor, increasing the cost.
The Value Matrix
To help you make the right choice, we’ve developed a simple framework. Identify which category your project falls into to quickly narrow down the best type of service.
- For Quick, Testing Prototypes: Your priority is speed and low cost. You need to get a physical part in your hands quickly to check form and fit, and you plan to make changes. The surface finish is not critical. In this category, services like PCBWay and JLCPCB excel. Their rapid turnaround and aggressive pricing allow you to print multiple design versions without breaking your budget.
- Für Anzeigemodelle & Miniatures: Hier, your priority is maximum precision and a flawless surface finish. You are creating an aesthetic object where every detail matters. Layer lines and support marks are unacceptable. For these projects, look for services that specialize in high-resolution printing. Shapeways is a top contender, delivering a final product that’s ready for display or painting. You can also find specialized, high-quality suppliers through Craftcloud.
- For Functional/Mechanical Parts: In diesem Fall, material properties and dimensional accuracy are most important. You’re building a part that needs to withstand stress, fit perfectly with other components, or possess specific characteristics like heat resistance. The service’s industrial credibility matters. Xometry is the clear choice here, with its focus on engineering-grade materials, enge Toleranzen, and quality certifications.
- For General All-Rounders: Your project needs a good balance of quality, Geschwindigkeit, und Kosten. It’s not a rough prototype, but it’s also not a high-end final product. You want a great-looking part without paying extra. This is where a marketplace like Craftcloud shines. It allows you to sort through various suppliers to find the perfect sweet spot that meets your project’s unique balance of needs.
Turnaround Times & Versand
When planning your project, it’s crucial to understand the entire timeline, from the moment you upload your file to when the part is in your hands. “Turnaround time” is not the same as “delivery time.”
Production Lead Times
Instant printing is a myth. Even for a small part, the professional production process takes time. A typical lead time of 1-5 business days is standard and includes several steps:
1. File Check: An engineer or automated system reviews your model for printability.
2. Print Queue: Your part is scheduled and placed in a queue with other orders.
3. Drucken: The actual printing process, which can take several hours depending on part height.
4. Nachbearbeitung: This is the most labor-intensive stage. The part is washed in a solvent to remove excess liquid resin, supports are carefully removed, and the part is cured in a UV chamber to achieve its final strength and stability.
Shipping Speeds and Costs
After production is complete, shipping time is added to the total timeline. Most services offer a choice between economy and express shipping. An economy option from an international supplier might take 5-10 Tage, while a domestic express option could arrive overnight.
For our benchmark part, the estimated total delivery times were:
- PCBWay (Express): 2 days production + 3 days shipping = ~5 days total
- JLCPCB (Wirtschaft): 3 days production + 7 days shipping = ~10 days total
- Craftcloud (Ausgewogen): 4 days production + 4 days shipping = ~8 days total
- Xometrie (Standard): 5 days production + 2 days shipping = ~7 days total
- Formbahnen (Standard): 6 days production + 3 days shipping = ~9 days total
Always factor in both production and shipping time when you have a firm deadline.
Preparing Your 3D Model
The quality of your final print starts with the quality of your digital file. By following a few best practices before you upload, you can prevent print failures, Kosten senken, and achieve a better result.
Pre-Upload Checklist
We recommend running through this checklist before submitting any model to a resin printing service.
- Ensure a Watertight (Manifold) Modell: Your 3D mesh must be a completely sealed, solid object. Any holes or non-manifold geometry will confuse the slicing software and cause print failures. Most 3D modeling software has tools to check for and repair these issues.
- Check Minimum Wall Thickness: Resin parts can be fragile if walls are too thin. They can break during printing or post-processing. A safe minimum wall thickness for most standard resins is between 0.8mm and 1.0mm. For delicate features, try to stay above 0.5mm.
- Hollow Your Model & Add Drain Holes: This is the single best way to save money on resin prints. Hollowing a large model dramatically reduces its volume, and therefore its cost. If you hollow a model, you must add at least two drain holes (minimum 2-3mm diameter). This allows trapped liquid resin to escape and prevents pressure buildup that could crack the part during curing. Place holes in inconspicuous areas, like the underside of the base.
- Unterstützung: Let the Service Handle It (Normalerweise): Placing supports for resin printing is an art form. It requires expertise to orient the part correctly and place supports that provide stability without damaging fine details. Für 99% of users, it is best to upload your model without supports and let the service’s experts handle it. They are responsible for a successful print. Advanced users may pre-support models for very specific needs, but it’s generally not recommended.
- Choose the Right File Format: The STL file is the universal standard, but it’s an old format. If the service accepts it, we recommend using 3MF. The 3MF format is more modern and can contain more information, including units, Farbe, und Materialien, reducing the chance of errors. If 3MF is not an option, a high-resolution STL is the perfect backup.
Making Your Final Choice
By now, you should have a clear picture of the resin printing service landscape. Der “am besten” service is entirely dependent on your project’s goals. By aligning your needs with the right provider, you can guarantee a successful outcome.
